Hello! My music isn't playing there. Oh yeah, dude, I have been jamming to some Ashni. Holy—how's it going? Holy—let me catch up on the chat. Arino here, I got to re-nagle my UI. I put my stream to explicit mode, so now I can say—really loud. Um, I don't know, we swear enough on this stream that I was fine putting it to explicit. All right, let me check up. Scura, what up? Showered and fresh shirts. Where is the C? Oh—um, I have a candle nearby right now. I kind of have walled myself in a corner here, so we'll maybe grab one when it gets darker. I'm getting warm, getting hot. Maybe I don't need my fuzzy slippers on. Maybe that's the problem. Um, hey Des, how's it going today? Ping PC load letter from Sirius. Sergio, oh yeah, we'll be loading some letters today. Meta Construct, thank you so much for the 12 months—one whole year! Oh man, guys, have any of you tried to emulate a kernel module in an emulator similar to what Gamoo developed on stream? I don't know, you're asking chat. Chat is the real responsible monolith here. Is this meme stream? Oh yeah, only memes. This is—this is only memes here. Um, cute stream, hell yeah! Oh man, classic htop aesthetic. Oh yeah, let me get the—here we go. There we go! All right, get that agop aesthetic. We should make an agop CPU usage starting—ah, stream starting soon. Yeah, I need to do some like channel points things, so remind me when I catch up on chat. I got something I have to announce or something like that. Um, let's get rudat printer. What printer are we hacking? Well, chat's going to decide, isn't that fun? Chat gets control when Goo is today. Fu Jam, not all bald people are the same! Okay, ah, oh come on here, I was wanting to go to sleep. Yeah, no sleep for you. Um, I like the screen with—I like the screen with a view of all the screens. Oh yeah, isn't that a good thing? It's recursive; eventually, the pixels just run out. Historic superb owl! Oh yeah, today's the Super Bowl. Cool, can't wait to tune into that one. Is sports? I hope they put the ball into the net. It's gonna be good. Um, ah, Zerotic was taken. Thank you so much for the four months of support! Hell yeah, still no music. Oh yeah, you can't hear the music. Although technically, technically I think Twitch has made it a little bit easier to stream music where you stream the music, but you don't record it or put it to the VODs. I need to figure that out at some point in time. Hey, Dev Angels, how's it going? Who's this old man? Is that R1 pre-stream? Oh no, we're ranked three in the US right now. I don't know, the rank one and two spots are pretty, pretty—you know, they're a couple Sigma out, so it's going to be hard to catch them. I think I can, but it's going to be hard. Like, they're just playing in much different raids and healing. Ultimately, you can't heal people who aren't taking damage. Damage! So sometimes the strategies and the way that certain groups play makes it easier to get better healing. So whatever. Um, those headphones sound really nice. Great choice! Yeah, these are fantastic. If you want a nice comfy pair of headphones that you can wear all day and are light—and they're open ear. Open ear is bad because other people can hear what you're hearing, but they're good if you don't listen to things super loud and you want to be able to actually hear what's going around. Uh, around you, like if you want to hear if someone's knocking or something like that. So, all right, Serial Photo G, thank you so much for the Twitch Prime! I just sent an employer a rejection letter. Dear employer—sorry, dear prospective employer—you. No, I love turning down offers, to be honest. I mean, I don't know if you're turning down an offer or like rejecting them for some other thing, but I hope it was good and healthy for you. Um, let's see. Do you agree that Windows 10 sucks? I mean, I personally really like the NT kernel. I think it's a fantastic kernel, and I think it's beautiful, and I think it's really well written and some of the best code in the world. I don't know if I like the Windows userland. Um, it can be bodied. Um, are you not interested in the big sports event? I don't give two— to be honest. Socially, I love watching football. Like, uh, and not football, but football—American football. Uh, I think it's really fun to just—it's an excuse to get drunk, let's be honest. Like all holidays and all social events, it's an excuse to get drunk or do whatever you like to do when you're social. If that's, you know, just get together with friends and hang out and make food and eat a bunch of dessert and whatever the— you do, or who cares. Um, it's an excuse to hang out, and after a year of COVID, I literally would do anything for an excuse to—hang out. I don't care if it's something I don't like doing; I would do it. Um, hell yeah! Will we be going off a firmware so we at home can play along? So ask that when I catch up on chat again. Um, chck shell. Oh yeah, we need to have like a Twitch Plays command injection. Dance W Park, thank you so much for the Twitch Prime! Hell yeah! Strawberry Hacker, thank you so much for the five months of support! Paul Gino, OBS has an option for Twitch VOD audio now. I'm curious if that is an OBS thing or a Twitch thing because I don't see anything like that, but I'm also on Linux, which means I might get features like that a bit later. Um, but I will maybe figure that out. That would be absolute POG because internally I record my microphone, my desktop audio, and my voice chat. So I kind of have a mixer here, and I have a couple audio sources. I actually have like in-game audio, desktop, everything else, music, and like voice chat, as well as my microphone. And then, uh, yeah, like all of these things I basically have stored as different audio streams in the recorded file. So in post, I can add and remove something. So things that you have never heard on stream, like my desktop audio, are still being recorded if I do want to for some reason add them back in in post, uh, in a video or a VOD or something like that. Um, so, uh, I do that locally, but I haven't seen an option for sending that upstream. I don't know; I haven't really looked around too much. So we need more screen clickbait! Oh hell yeah! Um, hi there! Was—hi there! Already exposed your task for today? Yeah, we're going to be hacking a printer, and we'll go into that a little bit more as I catch up on chat that keeps posting messages, so I never catch up. Um, thank you so much, Zerotic was taken, for the 500 Bitties! Just throw 500 Bitties. Anyone get that reference? I've been binge-watching that streamer as well. Um, sometimes the stratus to scam get damaged on—I—my stats—me—hey, Moose Mounted Mage, how are you doing today? Hope your day is wonderful. Glad to see you yesterday and pone some noobs; you know that was pretty good. Um, do you plan new fuzzing streams? Uh, maybe similar to 10 years Android end day from where old Colel would be neat. That's kind of what we're doing today. Well, not necessarily fuzzing, but hacking. Um, honestly, I've been thinking a little bit about it. I think I might try to do more like short-term hacking things on stream than long-term dev projects. I would really like to do fuzz on stream, but there are some days where I just don't feel like streaming, but I also still need fuzz, and I'm in this really hard predicament where I want to develop it to add features that I need, but I want to do it when I stream. And sometimes the time when I need the features does not line up with when I can stream or when I feel like streaming. Um, so I might try to do more just random things where the entire project is disjoint from anything that I would potentially bottleneck on in real life. Um, that's kind of a plan, I think. Also, they just engage more people; they're just more fun. Like this printer hacking—oh God, it might not be fun. Uh, it should be fun, I'm kidding. It's going to be a blast! T, oh thank you so much for the three months of support! And Zerotic was taken, thank you so much for gifting a tier one sub, Arino! Um, hell yeah! Good cheers! Dropped you a bunch of interesting links on Discord. Check out the last monster 6502. I feel like I've heard of that. I feel like I've heard of that. Um, I will have to check that. Oh yes, I have seen this! It's where they made—yeah, um, unless this is a completely new or recent thing, this is like a 6502 that's implemented with discrete logic on a board, isn't it? Yeah, yeah, they like literally just put all the transistors on a PCB. Yeah, this thing is so cool! It's just a bunch of MOSFETs on a board. If people haven't seen, here is the link, Arino. Um, let's see. Uh, I from Microsoft think the kernel is great. Please, Papa, send me more money! Um, how did you learn to do programming? I just kind of did random projects that I thought were fun. Uh, obviously, I had a couple good mentors growing up, but I just always found it interesting. I actually started off with 3D modeling first, which kind of just got me on the computer a lot. And then from there, learning just like basic was a pretty natural progression. How does one see the NT kernel with a big enough microscope? Uh, are there any plans—uh, when you C—when you will continue fuzzing? I don't know; I kind of hit on that a second ago. I'm not 100% sure. Um, wasn't an offer; they gave me a code test. Their framework was C++ in Java style—everything was virtual object orientation with at least four files of coupling. My favorite! Why are you using Gentoo? Because it builds everything from source, which means I have a little bit more control over the system, which I really like. From OBS Studio 21.6—uh, I don't know what version of OBS I have, to be honest. OBS version I have 26.1. Yeah, 26.1. Okay, maybe it's been in there a while. Shower stream when? Uh, Moose Mounted Mage, you're going to have to subscribe to my OnlyFans for that content. Um, OBS settings output Twitch VOD track. Oh yeah, I do see that. Okay, cool! Yeah, um, that actually will be really easy for me to set up, so I will look into doing that. I don't know what the restrictions are for streaming. I don't know if I have to use like the Twitch music program thing. I think that is Windows only, but yeah, I should be able to split that up. Um, so yeah, hopefully that's something I can do. How did you learn how to hack? I just was really interested in breaking things. I learned a lot of like low-level programming, assembly, and C pretty early, and it was a pretty natural progression from there. But I never—I never learned how to hack. I learned how computers work, and then I kind of derived how to hack from that, which is not normal. I would say it's pretty common for a lot of the very skilled hackers, but for like the new wave of hackers kind of getting into things, there's just so many resources on how to do it now that you can kind of learn in a more traditional sense. Although I don't necessarily encourage that because hacking is, in my opinion—uh, maybe not web hacking; I can't really speak to that too much—but at least for low-level hacking, like binary security stuff that I do, hacking is literally just about adopting. And adopting is typically about understanding how things fundamentally work such that you don't have to read a guide or read a tutorial on something. How something works, you just can infer how something works by understanding how the underlying thing works. Right? If like we've looked at other architectures on stream that I have never written assembly for, but I can still read the assembly because I just know how processors are designed and what features they have. Obviously, there are certain aspects that I would have to look up in a reference, but I can for the most part understand what's going on even when I come across weird instructions because I know that some architectures have these weird instructions like different fences or like relaxed orderings that lead to weird instructions or suffixes, and I can typically infer what those things are. So I would say hacking, it's really important about kind of figuring that out. Um, I might have given you the bad language. I don't know where I got my potty mouth from, but I've had it since I was in elementary school, and my parents did not really swear. Uh, my dad would like get mad and swear at like football games, but like there was not that much swearing. I didn't really swear on my parents until I moved out. Um, way more fun than the Super Bowl! I like everyone has their—everyone has their way. OnlyCode.com, is that a real thing? Let me see. Oh no, it's not a thing. Name not resolved. Does that mean it's up for grabs or just no one is hosting anything on it? Started learning Rust. I'm using the Rust book in rust-lang.org. Is it a good start? It's a fantastic start! That's actually the only reference I've ever read for the Rust language. I've never read anything else on how to write Rust. Um, plenty of non-copyrighted music too if you want some background tunes. Unfortunately, it doesn't work like that. Uh, the tunes are not copyrighted, which means streamers and YouTubers and people use them as part of their videos or streams, and then those videos get copyrighted because their content that's being produced, and then the songs end up getting picked up as copyrighted even though the songs are not. Um, it's just such a fuzzy system that it's—I don't care if it's non-copyright or not. I'm okay with streaming music because there's a lot more like wishy-washy gray area there, but in terms of things getting recorded, I'm just still way too skeptical. Um, the main name that's not up for grabs is registered by Alibaba. Arm printers, crap! Anyways, hi, yeah, fairies! Um, how to post a link? Oh yeah, I actually turned off link posting. Only mods can post links. Uh, that's just kind of heightened security. Like, we've had people posting hack links before in the past, and while we have a pretty smart audience here, there's still a non-zero risk, right? So I just, you know, it reduces clutter, and I actually lock down a couple things on Twitch. There are things that you might notice, like the mature viewing stuff that I kind of went through, and I selected things that I'm like, do most chatters need this? If the answer is no, I turned a lot of things off. So, um, hell yeah! I'm not super picky about links, but it's just not necessary for most comms in my opinion. Um, have you worked on Rust SE before or planned to do so in the future? Not really. Um, I just suck at working with groups. I suck at working on group projects, and I suck at working on team things, and I just at this point kind of avoid it because it's just not something that I often enjoy. Unfortunately, like I just—I like the ability to have mood swings and just—disappear from society for a month like I kind of did in like the last month. Um, and sometimes it's really hard to work on teams when you want to just be able to disappear like that. So, yeah, I don't know. Um, still remember this lame malware sent by some skiddy several months ago? Yeah, that was actually a great moment! That was so—fun! All right, chat, I think I am all caught up on chat. Sorry if I missed any donations or subs or anything. Actually, let me make sure I can see donations because I don't have that open. It's on my Streamlabs. Um, let me do this—log in with Twitch. Um, I always miss donations, and I feel bad, but, uh, you know, H Chad has learned to deal with the neglect. Looks like I have caught everything, although some of the weird—okay, yeah, huh. All right, anyways, uh, we should be good there. As technically a ghost for six or seven months doing mostly doing nothing? Mostly, yeah, yeah, I know that feel. Sometimes it just feels good. Ah, all right, announcement time! Oh— I mean, I was going to try and keep this thing a secret, but I can't—I can't keep secrets when chat is just twisting my arm. But about 20 minutes before stream, I YOLO bought a camera, so we're hopefully going to get a better camera quality going on the stream, which is going to be really fun! So, uh, not only is it just going to be a nicer camera—uh, so this camera is more for taking photos, which means the HDMI output is more for like hooking it up to a TV so you can like look at photos with like a group of people, but not actually get any quality. So the basically the software side of this camera is pretty ass. Like the back end to the HDMI, it's just like—I think it, yeah, I think it only can do 1080p 30 FPS. Uh, the encoding is dog— the like bit rate that I can get out of that HDMI is really bad. Um, so unfortunately, the camera quality that you see obviously on stream, it's a worse quality than what I see, but like even recorded locally with lossless storage, the quality is so much worse than what the camera actually is capable of doing. Unfortunately, it's just—this is not meant to stream live HDMI feeds. So I bought a, um, I bought an A7S Mark III, which is pretty much the best non-ridiculous camera that you can possibly get for video. Like, obviously, people are going to be like, "No, no, that's not true! This is ah blah!" It has unbelievable video quality and low light quality. I paired it with a very low light friendly lens. I got a—I got a fixed—uh, whatever the—I got a fixed lens, f1.4, so it should have remarkably good, uh, like low light quality, which means that at night when we do night streams—which is pretty much only—I can probably turn off the lights in here, and we can get like a pretty good video quality with kind of a night, you know, screen glow aesthetic, which I can't do with this camera because things just get too washed out. Um, I also will be able to use an autofocus on that camera where this autofocus, uh, pulses way too much that I have it off, and I'm—you're on a fixed focus right now, which kind of sucks if I want to do more dynamic things with the camera. So, um, yeah, basically that the camera that I'm getting can do 4K 120 FPS. Uh, obviously to my computer, it's only going to be 1080p 60, but it is, first of all, a mirrorless camera, which is kind of a negative for photos, but it is a positive in my opinion for video because it means the photo and the video and the processing and HDMI all coming from the same place, right? Like, I know that's kind of weird, but sometimes these mirrored cameras have like a lower quality when you are, you know, using this live view mode, right? When I'm not actually— Um, I don't know, it's—it's—but it's going to be a big improvement. F1.4, you'll be able to see Martians from here if you aim it right! I mean, uh, I don't know if you're meaning, but it doesn't deal with the zoom. It's just the—it's just the aperture. Basically, f1.4 means that the aperture opens more, so you'll basically find that the, um, you'll find that on cameras, the fixed lenses where you can't zoom, you can't change the zoom like I can on this one, which you can barely see that I'm doing it, but basically the extra mechanicals that you need typically make more bulky area around the camera, which means the aperture cannot open as wide, right? Or you can't have as big of an aperture. Um, and basically the bigger the aperture, the more light gets led in it. Also means the blurrier the image is because if you think about it, if you have a pinhole aperture like this tiny, tiny just a speck, the only light that can really come in is light that is coming in almost directly at the camera. So if you think as photons as just random rays, it basically has to come head-on to go through that aperture, which means at a smaller aperture, you get a better like depth of field because you are getting a more like consistent image. If that makes—it's kind of weird, but basically with a larger aperture, you can get more— photons hitting the sensor, which means you can get better lower light recording. It's a really—like I'm not a camera person, but that's basically what it is. So the new lens that I have will not be able to zoom, which means that I will just have to physically move the camera if I want to get closer or further away, but it means that the camera has less moving internals and just less internals in general, which means you typically end up with a little bit crisper and better of an image, right? It's basically, you know, a master of one, jack of none sort of thing. So I'm super excited about that! All right, have a good stream! I expect to see a VOD. It's a little late here; work early tomorrow. We got to catch up sometime. I did a stream with 5K concurrent views—holy [__]! That is amazing! Hell yeah! I hope that felt fantastic, and I hope you do more of those in the future. So yeah, have some good sleep. Thank you for the 100 Bitties, and I will talk to you soon. Um, feels like the difference in crispiness is pretty low nowadays. Yeah, really, the main reason I want it is just that low light condition. The A7S Mark III just has really good low light in general; like, it is a great low light sensor, which means I really wanted to emphasize one of the biggest qualities of this camera by getting a lens that also had really good low light conditions. Obviously, I'll just get more lenses as I need them, but at least for streaming, where I'm not really zooming or moving the camera at all, I think it's better to get a fixed lens in this case. Um, you're basically talking about the lens irregularities adding up to a decreased image quality. Yeah, exactly! It doesn't matter too much, but yeah, the biggest quality improvement is not actually going to be anything related to sensor or lens or the camera; it's literally just the HDMI output is designed to output to HDMI, right? It is designed for that camera that you output HDMI to an external capture device, and that's how you do serious movie filming. Like, when you're filming a shot for a movie, you output the video over HDMI and record it on an external device. And that means that, unlike this camera, where HDMI is kind of an afterthought so you can view things on a bigger screen when you're doing preliminary deletion and checking of images, this HDMI is literally better than the camera. The HDMI actually outputs a better quality than what the camera can internally record because over HDMI, it can do raw streaming, where it basically streams the raw sensor data. Um, so I'm not actually going to be able to record that because I'm not getting an external recorder. I will maybe eventually, and the capture card in my computer and my stream are only 1080p, so I'll turn it down to 1080p60 anyways. But yeah, serious movies use HDMI! Oh yeah, for sure! Um, yeah, like the A7S Mark III will commonly be used as a B-roll camera on real movies and as an A-roll camera on like not the biggest [__] movies, but big movies, right? Like, serious, serious YouTube videos—it is a really, really good camera. It is basically the best camera that you can get without going to like RED or Blackmagic level quality. So, all right, let's see here. If you want to burn money, yeah, I would say the camera that I got, the A7S Mark III, is probably about as close as you can get to extremely good quality without getting that—it is already on an exponential curve, right? Like, you can get a really good 4K 60, like on a YouTube video, indistinguishable quality from a $5,000 camera. You can get that for like $1,000 or $2,000. So I have gone a little bit above and beyond to a camera that is a little bit better than probably what is really discernible in a camera, but there are just some nice features—mainly like the low light conditions that are really nice. So I'm already in the exponential curve. So what else? But yeah, that's the new news. No, I'm also gonna go sleep. Yeah, get some good sleeps! Thank you for stopping by. But yeah, the A7S III can record 750 megabits bitrate locally, so it can do something called intraframe video. And basically, intraframe video, unlike most video formats that use some of the fact that most frames are pretty comparable and thus do have differential compression between the frames, right? Like right now, this background right here, when it's getting encoded to you, this is probably not actually being re-encoded except for keyframes. But intraframe basically means that each frame is compressed independently, and it basically means that every frame is a keyframe. And you'll find that when I have an option to get something that has precision and something that doesn't have precision, I will always pay into the exponential curve to get precision because it's just fun; it's fascinating to me. So yeah, photography is 90% lighting, though. You should think about that a bit. That's the one reason why I wanted this low light camera because it will allow me to have a more natural setup where I will be able to record things a little bit more how they appear in reality without setting up very heavy fake studio lighting. Um, because I like that organic, natural feel. Of course, I know how to make good video; I know how to set up lighting, and ultimately for streaming, I prefer the more realistic thing. I also don't like having lights [__] blasting in my eyes to get a good video. Yeah, the A7S Mark II is like $3,500, and then the lens is like $1,500. It was like five grand for the lens and the camera, which is pretty expensive. Like, it is a serious camera, but I also appreciate things like that. So yeah, the next tier for like a bigger improvement are like 8K cameras and [__] where you're pushing the $20K plus to like $50K boundary. So is the new camera just for Twitch? No, it's not. Um, what was your first camera? Well, this is a D5300, which is like my first real DSLR-style camera. I mean, I had like a handheld pocket camera in, I don't know, middle school or high school or something, kind of before you had cameras on phones where you just needed a little pocket camera. It's just like a $200 Sony camera or something. Um, yeah, RED camera for streaming? Yeah, I don't know. I'm not a camera person; I want to make that very clear. I'm not a camera person. This camera is way out of my league of skill, although I haven't been too intimidated by the skill required to use cameras. I'm not saying photography is easy because that requires having a good eye for situations and things that deserve photos and picking the right lenses. But in terms of mechanically getting a good image out of a camera, like basically playing with all the mechanics, regardless of the beautifulness of what you're doing or the color correction or things like that, like the post-processing to make good images and videos, just the raw capturing how it looks in real life better, I've really never had a problem with that. Um, but yeah, all right, chat. I think it is time. I think it is time to clean up my desk. Chat, you ready? You ready to clean? Oh, [__]! I might have to—I don't know what I'm going to do about my microphone here. I can either go get a lapel mic, or I can turn up the gain for this, and we might have a little bit shittier mic quality. Um, I need to do work over there, which you can't see over there, but I'm not gonna be able to stick the mic in my face. So, um, yeah, I didn't even think about that. Well, yeah, sucks to suck, chat. Sorry! All right, chat, so you have to make a decision now. Um, so the decision that chat has to make right now—I got to make sure I don't have anything too revealing on my other desk, and I do not. So chat, chat, chat, chat—more specifically, mods—I think I do have mods here. Um, we're going to make a poll here. Um, do we want to hack this Canon MX—a Canon Pixma MX 492? That is option number one. Option number one! Or do you want to hack—and the microphone's going to be [__]. I'm sorry! We can also hack a—this is an Epson something, Home XP 440. Oh, there's an Expression Home XP 440. There's your other option, the Epson. Look shittier, I think. These are all pretty much comparable price or [__]. I almost tripped! Or a Brother [__] Code JW J485DW. So those are the three options that we can hack. Um, I've never actually written an exploit or hacked any of these devices, but I have disassembled them, as I was showing a friend basically how to take apart devices and stuff. But I don't think that's really going to spoil anything here because the second we actually do stuff—oh yeah, I didn't—yeah, we're taking these apart to get the firmware. We're not going to actually download the firmware; we're going to desolder the chips and read the firmware. Um, not because we necessarily have to, but because we can. It's more interesting; it's more fun. And [__] you! Um, yeah, so we're going to actually be taking these apart and then desoldering the—we're going to identify whatever is storing the firmware, we're going to desolder them, and then we're going to dump the firmware as it is on the flash, which means that we will actually be looking at the firmware for the device that we have, not a specific version or some [__] online. I'm not going to update these; I'm just going to [__] get the firmware that's literally on them. So even if they got backdoored when they got shipped to me, we'll have the implant. So that is what we're going to be doing. Um, all right, yeah, current poll. It looks like we do have a poll. Sweet! Thank you! So yeah, everyone vote in the poll. There is some amount of time left—looks like maybe two minutes or something. No, JTAG, I actually have never done JTAG in my life. Um, so yeah, we will not be doing a JTAG. I don't have a JTAG reader. I mean, maybe we'll do JTAG if we buy a JTAG reader and continue the series, but we will not be doing that today. Um, but what will basically be on the menu today will be desoldering the chip, basically showing how that's done, reading the firmware off the chip, showing how that's done, and then probably decrypting or doing whatever we need to do to actually view the firmware, which will require some reverse engineering, which we'll do in Ghidra. Um, and then once we have the decrypted firmware—or probably more specifically, not decrypted but decompressed—the firmware is very likely decompressed on all of these devices, so we will decompress it such that we can see strings and we can view code. Once we have done that, we're going to basically do what I consider finding an oracle, which is typically connecting to some random network service on these devices and finding a unique string, whether it's like a version string or like, you know, "Brother printer service 4.0" is like a message that you get when you netcat into a different port. Um, and what we will do is look for that oracle in the code, and we'll basically try to find—once we have dumped the firmware, we're going to try to find a correlation between things that we do to these devices and the code itself. Basically, we're going to try to find where the code is that is responsible for handling certain commands. Once we have done that, we'll maybe try and find an exploit. Um, if we cannot trivially find an exploit, then we'll probably take them apart again, implant them, basically by figuring out the compression and decompression, and basically decompress it, implant it by maybe removing a length check or literally by injecting code that gives us arbitrary code execution, putting the chip back in, and then using that implant to image the running device such that we can then fuzz it. And while that is cheating to get code execution, it's not cheating if you used it as a research tool in the same way I would do that to an iPhone. If I can take apart an iPhone and implant it physically using tweezers and a soldering iron, and that allows me to then get access to arbitrary code execution that lets me look deeper for real bugs, that's a totally valid strategy. And that's the strategy that I use for most devices. Um, I will basically always try to get code execution on a device in one or two days, and basically I will look for an exploit for maybe eight hours. And if I can trivially get code execution in one of these devices, then I will just use an exploit. But if an exploit is going to take a couple of days to find, then I will just implant it using literally everything that I have at my hands because I don't care. Um, it is a totally valid way of going about doing things. Do you expect an exploit in less than 12 hours? Honestly, hard to say. From my experience, some printers just have very little attack surface. They'll pretty much—they're always going to have like printing attack surface, which is normally like PostScript or some complex file format. And unfortunately, those are usually relatively hard to find bugs in because they are massive. It's like finding a bug in Adobe Reader by just opening up—even though it's riddled with bugs, it doesn't mean that it's easy to find a bug because there is so much [__] code. Um, but sometimes these devices will have shitty services that are just custom services for like random network interactions, and sometimes those are really easy to find bugs in. We could also maybe try and find USB bugs in these where we can plug into the USB port on them and we can look for a USB exploitable bug, maybe a USB stack bug, which are typically a lot easier to find than network bugs because network things—I think we will find that all of these devices probably use a commercial off-the-shelf, probably closed-source printing engine, right? You know, one of these companies will go and they'll purchase an embedded web server that's designed for printers, and they will use that. And while those often are shittily written, it also means that there is some level of standardization, which often leads to these bugs getting fixed relatively quickly. Um, just because it's the servers that are used in these—like the software components, these are pretty universal, and the more universal something is, the harder it is to find low-hanging fruit because typically if you find a bug in a Brother printer and a Canon printer and they both use the same web server, it doesn't matter which one you started looking at; you will find the same bugs, and thus you'll get reports from either of the companies, if that makes sense. PLL result: Canon 52, Brother 35, Epson 8. All right, we'll be doing the Canon, which I think is the most expensive, the largest, and most complex out of the bunch. So I'm all down for that! It's not cheating if you can later exploit devices that you don't physically alter. Yes, absolutely! Um, physically altering devices is really important. I think it's something that is pretty underutilized for a lot of hackers. So all right, let's [__] go! I guess we're going to do the Canon printer. Um, all right, I have to set up my desk, and here's what I'm going to do. I'm going to turn up the gain for my microphone, and I'm going to put the microphone kind of just in this area. Um, it's going to probably be worse quality, and if it's really bad, we can switch to a lapel mic, which I can switch over to pretty easily. I just have to go grab it wherever it is. Um, but I would like more freedom here, so I think you need to refill your whiskey. Yeah, I do! All right, so test, test, test, test, test, test, test, test. How is that? So that—okay, that was better than I expected! So, um, I don't think I'm clipping anymore, although I am probably louder than I was before, actually, although I'm going to be facing this way, so I can't actually look at my gain without talking into the microphone. But I think that's pretty good. Um, it's going to be a lot more echoey, right? Is the gain too high? Like, am I clipping? If I get too loud, just let me know. It's remarkably good! Yeah, the—it's pretty far away. Like, so this is basically where I'll be sitting, so I actually can't look at the gain, so you'll have to tell me right now. Um, this is basically picking up like echoes, but this will allow me to just not look at my screen. So hopefully this works. Is that fine? It's fine? Okay! Um, is it fuzzy or shitty quality? Because if it is, then I can go to a lapel mic, which will get pops when I move my shirt. So this is like better in some ways than worse in others, if that makes sense. Uh, the mic is in the way. That's fine; the camera is in a temporary spot. Uh, okay, so I'm going to pull up Twitch on my phone such that I can see Twitch on chat and interact with you [__]. Um, where is Twitch? Twitch, Twitch, Twitch. So this will allow me to interact with the stream because I interact a lot. In fact, when I'm not at my computer, I'm probably going to interact more with chat. Uh, this is gonna be kind of funny. Oh man, Code M just started streaming! Hell yeah! Um, okay, my own stream and then Dash stream manager and then welcome to the chat room. Okay, I need the first person to post something in chat. Okay, light mode Twitch! Hell yeah! Okay, um, so the first thing that we need to do is basically set up our hardware environment, and I'm going to keep looking at the camera in a weird way, and I'm going to fix that. So I also don't know if you hear me when I'm over here. I'm just going to say stuff, but I'm going to assume it's something [__]. Um, so sorry! Sucks to suck! Um, yeah, and then that HDMI cable is very short. Yikes! That HDMI cable is very short, which is unfortunate. Um, yeah, so I can either—I'm just going to move my computer closer. You know, that is a viable strategy, and then I can get this a little further. I actually just ordered a couple of extra-long HDMI cables. I actually don't have my camera hooked up to the battery backup. All right, I think that's going to be okayish. Um, I can actually just move the desk closer if I need to. All right, okay, so um, I can hear you over there! Oh hell yeah! All right, so the first thing we're going to do is just move all of these phones. Um, okay, those Birkenstocks! Hell yeah, they are [__]! I like walled myself off. Um, is that all the fun? Oh, I missed one! Rip! Okay, uh, what else do I not need here? Now that all these phones are gone, I can move all of these charging cables. Um, let's see, we won't need that; we won't need this, and we'll just move pretty much everything else here. It's just a bunch of random electronics components and a lot of dust over to the corner. Okay, all right! Oh, there is a lot of dust! Yikes! Yikes! Remember, chat, always clean your work surfaces! You want to get that nice clean look! Look at that! That is a productive work environment! And then we move all of this [__] back over, which also brings over all the dust again. And then we clean this up. Oh, look at this! Cleaning, cleaning! I don't know what just rolled off the table, but it was probably important! All right, oh, look at that! Look at that! That's good enough! Clean, clean! That is straight gorgeous! Huh, what do we get? Oh, is that a 470 fad cap? Yes, it is! Micro fad, not actual farad; that would be ridiculous! Um, yeah, how's lighting? Lighting looks acceptable! I really wish I had a longer HDMI cable, but I actually don't think I have one. That might be my longest HDMI cable. [__] How do I mitigate this problem? How do I mitigate this problem? get a close-up of that QR code for you. If anyone wants to scan it, feel free! Alright, so we have a couple of interesting components here. This is clearly the main processor of the board, and it looks like we have some other connectors that are labeled. We have the **power**, **line feed**, and **carriage return**—which is pretty cool! Now, let's see what else we can find on this board. We have a few more connectors here, and it looks like we have some capacitors and resistors scattered around. This is a pretty standard layout for a printer board, but it’s always interesting to see how they’ve organized everything. Oh, and look at this! We have a little chip here. Let’s see if we can get a closer look at that. It looks like it might be a memory chip or something similar. Alright, let’s see if we can get some more light on this. The more light, the better! Okay, that looks good. Now, let’s focus in on that chip. It’s a little hard to read, but it looks like it has some kind of identification number on it. I’ll have to look that up later to see what it actually does. Now, let’s move over to this side of the board. We have some more connectors here, and it looks like we have a few more components. This is where the ink cartridges would connect, I believe. Alright, so we’ve got a good look at the main components of the board. Now, let’s see if we can find the flash memory chip that stores the firmware. That’s going to be our next target! Oh, and look at this! We have a little LED indicator here. This is probably used to show the status of the printer. It’s always nice to see those little details. Alright, let’s keep searching for that flash memory chip. It should be around here somewhere. Oh, and I see it! It’s right here! Let’s get a closer look at that. Alright, so this is definitely the flash memory chip. We’re going to need to desolder this to read the firmware off of it. Okay, so now that we’ve identified the chip, let’s get our tools ready for desoldering. We’ll need a soldering iron, some solder wick, and maybe some flux to make the process easier. Alright, chat, are you ready for some desoldering action? Let’s do this! First, we’ll heat up the soldering iron and get it nice and hot. Then, we’ll apply some flux to the pins of the chip to help the solder flow. Once the solder is melted, we’ll use the solder wick to soak up the excess solder. This should allow us to lift the chip off the board without damaging it. Alright, let’s get started! *Heating up the soldering iron...* Okay, it’s getting hot! Now, let’s apply some flux to the pins of the chip. *Applying flux...* Alright, now let’s melt the solder. *Melting solder...* And now, let’s use the solder wick to soak it up. *Using solder wick...* Alright, we’ve got the solder off! Now, let’s see if we can lift the chip off the board. *Gently lifting the chip...* And there we go! We’ve successfully desoldered the flash memory chip! Now, let’s get this chip ready for reading. We’ll need to connect it to our programmer to dump the firmware. Alright, chat, this is where the fun begins! Let’s see what kind of secrets this printer is hiding in its firmware! *Setting up the programmer...* Okay, we’re all set up! Now, let’s connect the chip to the programmer and see if we can read the firmware. *Connecting the chip...* Alright, let’s start the read process! *Starting to read the firmware...* And... we’re in! We’re reading the firmware now! Alright, chat, this is exciting! Let’s see what we can find in this firmware. *Reading the firmware...* Okay, we’ve got the firmware dumped! Now, let’s take a look at the contents. *Opening the firmware file...* Alright, here we go! Let’s see what we have in here. *Scanning through the firmware...* Oh, look at this! We have some interesting strings here. It looks like we have some network configuration settings and maybe some error messages. Alright, let’s keep digging! *Continuing to explore the firmware...* Oh, and look at this! We have some functions that look like they might handle print jobs. This could be where we find some vulnerabilities! Alright, chat, let’s keep exploring and see what we can find! Uh, okay, trying to get the best contrast for y'all. How's that look? Not bad, not bad, not bad. Is it not QR H? It's good enough. Has to be proprietary in-house indexing; doesn't scan anything. Rip, dude, rip the dream! Okay, so we got the ADF—I don't know what that is—we got the CIS FB, and we got the panel. So this is probably the control; like, this is probably the actual H EDF. This line is—this a line feed encoder? Is that like for indexing where the heads are? We got an NCU, an eject—don't know what that's for—and a WAN, so the wireless L here. Interesting, that is an eight-pin job. I wonder what that is talking over. I wonder if that's like an SDIO interface that they use there. Alright, so looking at it vertically, it doesn't really work too well, but this is a USB port, so it's a Foxconn component here. We've got a USB Type B connector, we've got a crystal oscillator there that's going to be running the whole system, and I guess I actually don't know how to read crystals. 24 JF4 M17 E—uh, is that a 24.7 or—oh no, this is a 24 MHz crystal, isn't it? Yeah, so what's fun about this is we should be able to—like, look! Yeah, you can see how that was etched in there. Isn't that cool? You can kind of see how the—how it was punched in there. You can see all the little dots of like the dot matrix punch printing of that onto the middle case. Isn't that kind of fun? Pew pew indeed! Okay, looking at other things, so those are all the connectors. This right here, um, this is very obviously a serial-based—this is a serial-based flash chip. So we've got a Winbond 2501 128 FVSC 1713. So 1713 is probably the date code. I don't know if that's the 13th week of 2017 or the 17th week of 2013, but it's probably the 13th week of 2017. I'm going to see if I can clean that off with a little bit of slobber. There we go, there we go, and that'll dry up. Okay, so we have—sometimes it's easier to read these when you actually zoom out more. Let me change the angles here. Um, there's actually a chip on the chip, so yeah, two 250 128 FV. I'm guessing this is a 128 megabit flash chip right here. So this is going to be an 8-pin serial. Looks like my friend did the soldering on that one. Yeah, wow! Okay, yeah, cool! So, uh, wow, that is hanging in there by a [__] thread. Has already been desoldered, this one has. Yeah, I did this as like a soldering chip practice thing with a friend. Ooh, ooh, yeah, that's fine. Not a big deal. Okay, so basically, if you've never done this stuff before, this is actually the chip that is going to contain the firmware. And the only reason that we know this is if we look at all of the chips. So before we do anything else, if we look at all of the chips on here, we have this, which is a Micron SEM M17 D9R ZH. This, just due to the form factor, right? It's kind of ridiculous, but due to the form factor, this is very obvious RAM. This is obviously like DRAM or some form of RAM. If we flip this over, we can kind of see—yeah, so here are going to be the VAs to that. I don't know how many pins are actually in use on here. I also don't know if this is a multi-layer board. I'm going to assume this board is not multi-layer, but it's hard to say. Anyway, this is obviously the DRAM, so that's one of the chips on the board. And there's this big chip, and basically the squarest most chip is always the processor. That's not actually the case, but this is definitely the processor on here. So I don't know if there's any information on here. I don't see any branding, so I'm guessing that they have branded—they probably purchased the chip and then they brand it off of someone. If anyone wants to look up these codes to try to find what this is, so the data sheet for the flash W25 Q18 FV—yeah, that probably is. Let me just make sure. Uh, 128 FV S0—oh, is it SC? FV—oh yeah, so basically you—in that data sheet, we can pull up that data sheet in a second. That SC or S0 or whatever that is, that's probably a designation about the speed. Probably S0 is like speed zero. Now, these numbers are sometimes pretty random, but the data sheet will likely reference specifically how to read these codes. And that's a cool thing about data sheets. Then the main processor, we have the DRAM on here, and then we have one more chip here, an A412 T731. I don't know what a TI 731 is. I don't actually know if that's a Texas Instruments, but I'm going to assume that this is probably a chip that just magically handles—you know what this is, right next to the CIS FB and the panel. And some of those wires are going to the panel. I'm trying to trace those out really quickly. I would imagine that this is probably an LCD controller; that would be my guess. So it's hard to say, but yeah, I don't know if anyone can find information on that TI 731. And then this right here is just a felt pad. There's actually nothing under here, so this is probably for a—you know, different model. They use the same board, so you can see there's a lot of unpopulated stuff around here. And this is just a felt pad; it literally is nothing. Got some power supply things here, so basically the power comes in here, right here, PWR. And then we have a couple more standard components. These are probably just going to be dividing down voltages to different voltages that we need. But everything else on here—there are very few discrete components on here, just a couple filtering caps and pull-up/pull-down resistors. And other than that, it's literally the flash chip, the CPU, the DRAM chip. This was probably an LCD controller or something of that type. If someone can find info, and of course we have an oscillator on here. There is nothing on the other side of the board at all, so I'm not even going to show you that other than some passives. But yeah, that's it. And the reason why it's so obvious that this is the CPU is 'cause it's the biggest thing. This is DRAM just due to the shape, and it's Micron, and this is the flash because it is an 8-pin small little thing, which is—flash chips are typically like that. And the 128 is a designation of the storage size, which is something that you can often infer from chips like that. So yeah, that's basically what we have there. There's really nothing else on this board. It's actually really boring. So TI 731, 8-bit LED binary counter, huh? So yeah, I would imagine that is actually being used for the display then. That's my guess, at least. Alright, so what we're going to do is we're going to desolder this chip. So we're just going to lift this chip off really [__] easily. We're just going to use a heat gun, which I will—if you remind me, I will show you after we get off the microscope view. But we're going to finish this up on the microscope. Ah, I [__] up that tape 'cause I jerked the camera, and I [__] it up more. Sucks to suck! Okay, getting stuff on my desk that have been on it, moving it to a spot so I don't [__] things up. Bad moving these so I don't lose the screws. Plugging this in. Okay, so, um, as I crawl through everything again. Alright, let's see if that tape resticks. Oh, it did! Oh, glorious! Alright, so I'm going to turn on my hot air gun, and I like how that's making all of my lights kind of flicker in here. That's sketch! Okay, um, so we're going to use a hot air gun to remove this chip, which will allow us to melt kind of all the solder. We just want to avoid melting this connector; that's really the only thing that we are concerned about is melting that one connector there. So all we're going to do—I'm going to go find a pliers, which I have on my desk, I'm pretty sure. Yeah, I've got a small little pair of pliers. Tweezers would make more sense here, but I actually don't own a good pair of tweezers, so I'm just going to use pliers here. And these are probably not the pliers that you're expecting to come in here, but those look pretty good. So all that matters is that I can get a decent amount of grab on here, and I just want to grab it lightly such that I can hold the board up. And hopefully, when I melt that solder, the chip will just fall off. So I'm waiting for my hot air gun to warm up a bit more, but basically, the goal is to just use the weight of the board, which is like an ounce, and use that to just drop the chip off once that melts. So I'm not actually really squeezing these pliers; I'm just trying to grab it a little bit here. Okay, um, at least that feels pretty hot. I don't know if it is at full temperature yet. We're going to come in here. I'm actually going to turn down the airflow. We're going to go to like six liters per minute of air through here. Okay, and there—okay, looks like we are able to melt solder. So it's hard to say if that one side has already been melted. It might be hard to get both sides at the same time here. I don't know if that's fully melting on that side, and unfortunately, I have to actually bring the gun a really long way. Come on! I think it lifted off that side, and there we go! The chip is off! Okay, beautiful! We can turn off that, and there's no collateral damage on the board. So that's it! So now we have this chip, and so that is the actual flash chip here, and we're going to read the firmware off of this. Yeah, that's it! [__] hacker man! Putting it on is the hard part! Putting it on is definitely the [__] hard part. I actually just have really shitty flux, and if you've ever done soldering with shitty flux, you'll know that, yeah, it makes things [__] hard. Okay, so what we're going to do is [__] [__] [__] [__] [__] [__] going for an adventure today, chat! And then eventually, once I have more cameras—sorry for bumping the microphone—yeah, this is kind of the setup that you didn't really get to see. We had kind of the microscope set up here, and you were down here, and that chip hasn't moved, so the chip is down here. But yeah, I had the bright lights on and then the hot air gun, which you can't really see. I have a hot air gun here, and so this is the wand that you saw poking in there, and it just basically blows hot air onto whatever you want hot enough to melt solder or whatever. I had that on heat setting five; it's a little bit hot, but I was trying to just do it quick. I wasn't too worried about damaging anything; it's not the most delicate piece of technology. So now that all of that's there, what we need to do is actually dump the firmware off of this. And to dump the firmware off of this—and I move the camera and [__] everything up—we are going to grab a reader that I have. So in here, I have a bunch of miscellaneous things, but let's not lose that chip. Let's just put it somewhere safe, like there. So I have a bunch of different readers. So basically, you can buy these off eBay. They're [__] like, I don't know, 100 bucks. This is a TL8662 Plus. If you just go onto eBay and you buy the most fully featured [__] set of components, I actually have two of them. That's basically what I have here. So that's all I have, and it comes with—if you buy, you can buy just the programmer, but if you don't buy the programmer, you'll get a bunch of these adapters, which are used to basically hold various chips. So the one that we're most interested in is very likely going to be this one because it is an 8-pin connector, and it's really hard without having—it's really hard to focus this. Sorry, chat! But basically, it's got like eight little pins in there, and we should be able to just socket the chip. So we'll see what we can do, and hopefully, I will—we'll try to get a better way to focus. But all we're going to do is grab that chip; we are going to align pin zero with the correct position, which honestly, this is going to be pretty hard to show on stream just 'cause these are just such small pieces. Align the chip and drop it in here, and then it's really important—really important—to make sure that the pins actually are being grabbed by the little grabby boys and make sure there's decent contact. If there's not good contact, then you'll have a problem. But basically, what I have done is I have socketed that chip in there. So now the chip is kind of grabbed in there. So those are like spring-loaded pins, and when you push down on this, basically the pins kind of retract, and you put it in there, and then the pins go back in. And on the back side, there's just this standard DIP-style packaging. So yeah, let me get my autofocus kind of working better here. Um, let's see. Oh yeah, okay! So all we're going to do is just whack this in the programmer, which is kind of the same process. Um, we're—well, we're just putting—oops! Put the other daughter board in there and socket it in this programmer. And at this point, as long as all of the pins are touching and we don't have like a piece of solder that's causing one of the pins to not connect up correctly or like push it off of the pads, we should be good. So we're just going to go find a USB cable for this, and we'll go over to the computer. So where would I have a USB cable? Um, oh man, I've got USB 3B cables. Printers might come with a cable. Yeah, printers don't come with [__] anymore. Luckily, it looks like I have one in this box. I probably came with the programmer, to be honest. Okay, so now what we can do is we can go back to the computer and, um, blimp blimp blimp. Sorry for touching the microphone. Um, how the [__]—how did I—how did I have that in there? There we go! There, something like that. Okay, okay! So now what we have to do is we have to find the software that we have to run for this. And let me point the camera up—not that up. That looks like a good amount of up. That looks like the pretty—that looks like the normal camera position. It's not too bad. And then we'll just get my focusing—oh, [__]! It's really hard to—there we go! Should be focused now. Alright, so what we can do is take a look at—let's get this program working. Um, so to do this, we're going to go get a Windows 7 VM running. And the reason we're going to get a Windows 7 VM running is because with basically all USB peripherals, the software always works better on Windows 7. Alright, let me—I'm going to temporarily do this. It's just a black screen; that's intended. Um, okay, okay! Where's my phone? There it is! Come on, come on! Alright, so we're going to grab Windows 7 here. Um, actually, I probably at one point had a Windows 7 VM, but not right now. Okay, Windows 7! Let's go! Windows 7 with Service Pack One! Ooh, yeah! Windows 7 Professional! Yeah, that looks good! Holy [__]! Why is that such a slow download? Six minutes? That is a scam! That is a scam! Eight—oh my God! Five minutes? Oh my God! Come on! Oh, it's speeding up! It's speeding up! The TCP window is adopting! Alright, chat, we're going to have to make bets on whether or not this firmware is going to be compressed or encrypted or whatever. Basically, if we run strings on this binary, will it have information in it? Okay, compressed, plain text, uh-oh! Or an XML? Thank you so much for the Twitch Prime! Hell yeah! Seven seconds left! Four, three—there we go! Two cores is fine; 40 gigs is fine. Internet access is fine. Honestly, maybe I don't want internet access on this. We don't have any other cards set up. Whatever! Let's go! Let's go! We'll get Vert I/O drivers here too. We're going to get this all nice and fancy. Alright, let me see if I missed anything. Bunch of follows! Thank you so much for all of those follows, everyone! Hell yeah! Oh, what's our prediction? Oh, compressed versus uncompressed! Oh, some big bets! Some big bets! I'm going to search for the firmware on here, so we're going to look—or not the firmware for this [__]—uh, TL8662 Plus. Yeah, there is actually a website on here. Um, www.xecu.com. Yeah, that's about what I expected. Oh, wait! Oh [__]! Yeah, okay! Oh, they have a new one! So this is what we have. We have the TL8662 Plus, and it can do all of these things! Look at all these things it can do! Oh, let's see if the English site works. Um, yeah, pin detection, 1.8 volts, NAND flash, MCU support, NOR flash, multi-programming, a bunch of different things. Status looks like in production, so this is basically still the thing that you get. So we want to get the TL—the just the programmer software here, and we'll just download this onto Linux, and then we'll copy it into the VM. So let's get—uh, is this the latest version? I'm just going to imagine it. Wait, 75, 2021, 128. This was updated literally like [__] a week ago! Hell yeah! Um, oh no, it doesn't look like we're making progress. Oh, we did it! Oh yeah! Okay, sweet! Um, uh, Win 7! Okay, easy chat, easy! Oh, I'm not sharing the screen! XD! XD! Got you, chat! Pranked you! Ha! Alright, it's fine! Yeah, we literally navigated a site in Chinese, but we did it! Okay, so we'll shut down this VM. Okay, now that we shut down this VM, we're going to switch over this to a—this—and we'll boot this. Okay, in before full secure boot chain! Ah, let's get an ex to doubt in chat! Uh-oh, we have to be Windows 8 or higher! Oh, what about this one? We can use this one though! Oh no, I don't think the software works on Windows 10, to be honest. the address and see what we can find. *Jumping to the address...* Alright, so this is definitely an interesting area.

This could be crucial for understanding how the device manages security settings. *Continuing to dig deeper...* Okay, we have some more functions here Alright, let's break this down step by step. 1. **Entry Point Analysis**: - It seems like you're trying to identify the entry point of the firmware. You mentioned addresses like `26FB` and `46FF3`, which appear to be garbage or not valid entry points. - You also noted that the instructions seem to be in ARM, and you were toggling between big-endian and little-endian formats. 2. **Instruction Set**: - You were analyzing the instructions and trying to determine if they were valid ARM instructions. It looks like you settled on using ARMv5T in little-endian mode, which seems to yield better results. 3. **Memory Mapping**: - You created a memory map for the firmware, specifying regions for flash and RAM. You identified the RAM size as 128 MIB, which is crucial for understanding how the firmware operates. 4. **Decompression Routine**: - You suspect that there is a decompression routine in the firmware. You noted that certain sections of code are likely responsible for initializing the processor and handling memory operations, including copying data from flash to RAM. 5. **Co-Processor Initialization**: - The repeated references to co-processor initialization suggest that the firmware is setting up various hardware components before executing the main application code. 6. **Function Naming**: - You started naming functions based on their operations, such as `initialize_copro` and `dram_timing_programming`, which is a good practice for keeping track of what each part of the code does. 7. **Branching and Execution Flow**: - You observed that the code branches to different addresses, which is typical in firmware where different routines are executed based on the state of the device. 8. **Cache Flushing**: - You speculated that certain operations might involve flushing caches, especially before jumping to the main application code. This is a common practice to ensure that the latest data is used. 9. **Final Thoughts**: - It seems like you're on the right track with your analysis. The combination of identifying entry points, understanding memory layout, and analyzing instruction flow will help you uncover the functionality of the firmware. 10. **Next Steps**: - Continue to explore the identified functions and their interactions. Look for patterns that might indicate vulnerabilities or areas of interest for further exploitation. Keep up the good work, and let’s see what else you can uncover in this firmware! Alright, so what we're going to do is we're going to perform a memory copy. To do this, we'll go into Canon from dumps. The first copy will be from RAM. The block size is 1, and the count is equal to the subtraction of these two addresses. Let me calculate that: `python hex(0x3A1234 - 0x207F0)` gives us `0x114964`. Now, we need to determine whether to use skip or offset; I always forget. The offset is `0x207F0`, and the size is `0x13314`. So, this should basically be the data that we see at `0x3A`—sorry, at `0xF000D2DE9` and so on, copied all the way down to `0x3A74`. Now, we should be able to load that into memory. To do that, we will split this region and say that the new block starts at `0x3A1234`. This is where it's going to be copied, so this is the first copy. Next, we will split this and say that the start address of this is at `0x3A3A74`. Now, we should have RAM from `0x39FFF`, which is good, and then `0x3A374` gives us more RAM, which is read-write-execute (RWX). Now, we will add the file bytes. We'll add to program RAM the first copy of the raw binary, and this will be at `0x3A1234`. We will label this as the first copy. I don't know what this is yet, but we'll figure it out. Then, we should hopefully be able to reanalyze and pick that up, so we can now see that what we're copying to is actually initialized, which is fine. This is now going to branch to here. This is technically code now. Let's disassemble it. The instruction `0xF02D9` is obviously doing a memory copy from R2 into P of R2. So, what we need to do is emulate this. Is this an address? No, this project is not accurate. What the heck? That's so confusing. Let's load this as ARMv8 and give it all the features. We're going to load this to `0x3A1234`. Here we go; there's definitely code in there. It wants to jump to this address. Is it just my processor mode? Can I change that? I don't know if I trust it, to be honest. Let's just say ARMv8 little-endian. You son of a gun! Get out of here! Alright, it's definitely not ARMv8, but we're just saying it is. Let's load it at flash. I told you the last time was not the last time we'd do this; we'd come back for this again, and I was right once again. No surprise there that I was right. Non-writable, then we are going to import this. Add this to `0x3A1234`. Some copy this. Okay, bam! Memory map. Yeah, it's technically writable, and then we are going to add something from RAM. The length is `0x3A1234`, rewritable and executable. We're going to add something that starts at `0x38A3A74`, and the length is `0x800000 - 0x3A3A74`. Hex that. This is RWX. More RAM. Okay, and then that's going until the end of RAM starting end. Those look good. Permissions look fine. Then we have to add, whoops, we'll say volatile. Okay, those look pretty good. Bam, bam, bam! Here we go! Disassemble this, and let's start doing some analysis. Let's go, mate! But just not in thumb mode. I checked the thumb mode on the other database, but whatever. Alright, so this is the copy, and then we branch. Oh baby, this is different! It just resolves that we branch to here. It's a smart cookie that branches to here. Okay, yep, it just basically slurped it all up. So here we are now; this is in RAM. Assume T-mode is 1. Yep, that looks good. T-mode is 1, and then this is—oh my God, this is what we were looking at before, and we said this looks like decompression. Is this going to be their decompression? This is advanced. Oh boy! Yeah, this looks like decompression for sure. Here's a reference to a string: "unknown compression method." Definitely compression! Okay, and this takes arguments. What are the arguments here? Setting—passing something to the stack that sets up parameters. It's probably like a `memzero` or something. Yeah, it's a `B0`, baby! That, my friends, is a `B0`. This is going to be the—what is this? This is the size. This is the size of whatever it is. Maybe it's going to `B0` out this. Oh yeah, look at that! Oh my—oh my God! No! Is that on the stack? Oh baby! Oh, wow! Look at that stack! Holy cow! Yeah, that's definitely `B0`. This is a—this is `B0`. Yay! We did it! Okay, alright. What is this? Is this going to be `memset`? No, it's not. What the heck? What the heck? Is this `malloc`? This is `malloc`. Oh my God, is this a heap? Oh baby, that's a heap! This is a—sorry, why is that not retyping it? Oh whoops! Uh, void star star. Then this is going to be element size, and this is a number of elements. There we go! So this is a—this is a 16-byte aligned allocator with a custom heap. Yay! Look at that! Isn't that cool? So we take the heap, we get the heap pointer, we get the number of elements, we multiply it by the element size, we then get the address of the heap, we add `0x10`, we mask it off so it's 16-byte aligned, and then we return that. Right? You're going to return that, right? Yeah, you're going to return that. Yeah, you're going to return that. Yeah, you're going to return that. Yeah, you're going to return that. Yeah, you're going to return that. Yeah, you're going to return that. Yeah, you're going to return that. Yeah, you're going to return that. Yeah, you're going to return that.

Yeah, you're going to return that. Yeah, you're going to return that. Yeah, you're going to return that. Yeah, you're going to return that. Yeah, you're going to return that. I think, um, maybe it's not necessarily `M Copy`. Uh, `Prem 3`, if it's equal to one, then we do some ORing stuff. Okay, um, yeah, this is definitely some like compression helper. It's not `me copy`. Yeah, yeah, okay, um, I don't like the use of like kind of these magical pointers. Um, what's this? Takes a lot more args. Oh, what is this? [__] man, whoa, no, no, no, no, no way, dude! The [__] is that? What is this, like Dynamic dispatch? [__] That's [__] dumb. Um, literal and Lang set code length, invalid L and length code. Um, before plain zip, this is honestly like pretty complex. Um, like I'm basically trying to figure out if this is intentionally obfuscated or not. Let's see, let's grab one of these magical constants right here. Let's grab this. Let's Google it. H, that's a bit manipulation. Okay, um, like this stuff all makes sense. This looks like standard decompression stuff. It's where there's like the [__] Dynamic dispatch that is very strange to me. Um, this is basically just hackers Delight here. Case one, if case zero, maybe we're just case zero. Um, let's see, where's that coming for? Uh, P of R3, 331, which is coming off PRAM 7. Um, and I can't believe it supports like multiple different decompression formats. This seems like so [__] overkill for a like little embedded device. Obviously, they just like bought this code and used it. It's probably some like OS that just provides this [__] or some like common bootloader. Unless this thing's like running [__] Linux and we're literally reversing grub right now. But `Prem 1`, uh, let's look at what this Dynamic dispatch looks like. Um, let's create a structure here, and we want to see, uh, `Prim 3`. Yeah, `Prim 3` is like a function pointer. Let's see. Uh, oops, let's see if `pram 3` is a function pointer. P of R3, a null P, R3. Sometimes it's null, sometimes it's one. Uh, 370 there else this. Um, we can technically hit either of those cases. I, R has to be zero, which means we have to go through this case, which means P R is going to actually get set on one of these. It'll get set either to four or to one, and then this `pram three`. Oh, this condition has to happen. `Prim one`, uh, 24 hex. Um, yeah, maybe it's Z. I don't know; that'd be fun. Uh, 24, 24, `pram` on 24. I don't think it's ZB though, to be honest. Um, if it is ZB, it's in some scuffed ass encoding mode. Alright, we want 24 hex off of this. 24 hex. Um, this is currently, we're just going to say this is, uh, size T8. Uh, this say 24 hex, I think. So divided by four, uh, is nine. Let's make this even bigger. Let's go to, uh, let's go to 10. Hopefully, that doesn't [__] anything up. Now we're looking at what sets nine on that, and it is this early Alec. Wait, no, this return is just an empty return. The strings point to inflate. Oh yeah, maybe it's just literally use it in, in which case we can, uh, decompress it pretty easily. Um, but yeah, so we have an early allocator here. So we basically are, we're passing in things here. We're passing in an early allocator. We're passing in a function. This is probably the error function that that's what this is. This is the error function that's being passed to, uh, whatever the compression algorithm is. Um, if you haven't noticed, I'm trying to pretend like we don't know what this decompression algorithm is. Uh, once we, if, if we like comprehensively understand what the decompression ELO is, then we'll just [__] use deflate or whatever. Um, but I'm approaching this as if this is unknown, right? Did he binwalk it? We did, but our goal is not to binwalk it, right? That's not really a valid—it's, I mean, it's a good skill, but it's not a hard skill to have, right? But yeah, these are basically, this is just going to dispatch to the air handler function, and then the error handling function just returns out. Um, so, um, searching con always helps. Yes, I'm familiar, but that's not what we're trying to do. We would have had this decompressed like five hours ago if, if—well, four hours ago if, uh, we were just trying to decompress it. But the goal is to, uh, basically reverse out of bootloader that is unknown. Um, okay, so this looks good. Val window SI is here, and then this will probably, if we see more Dynamic dispatch, it is probably to that object. So this probably is taking an extra paramet, uh, one of these ones that like can fail or something. I'm actually, we're going to do our, uh, we're going to do our analysis with, um, uh, where is it? Uh, decompiler parameter ID. Come on, okay. Um, there we go. And okay, so now we should have a little bit better, uh, setups here for these calls. I don't—is that actually taking all zeros to all args? Yeah, it's literally just passing zero to all args. Interesting. Okay, cool. Um, oh yeah, so this is like probably decompress window or something like that. Nifty, nifty, nifty, nifty. PV4, okay, nine, blah, blah, blah, bunch of pointers. The [__] are these? Oh, those are curious. Valid block type. Yeah, these are interesting. Seven Z five, huh? Okay, alright. Um, well, that load up a four D. These are basically mem copies, I guess. That's a zero. That's fill with FS, I guess. Those are REM sets, actually. And then this function, 77. Okay, okay. So these have the call to 24. Um, which means `Prem one` is going to be like the, basically the, uh, what is that? Local 34, that's `pram one`. Yep, that's like the global like decompression structure or whatever. Um, so what we can do is I'm trying to see how hard it would be to lift this into C. Um, this one looks a little bit rough. This is a pretty complex, um, decompression. Definitely not what I was expecting. I was expecting something a lot simpler. Uh, we know that those calls to code are knops, but we might need to type some of these things a bit more. Um, yeah, let's make these things a little bit stronger on types. So `undefine saving the stack H`. What is an undefined two? Is that two bytes? Let's see when it accesses that. Is it a two by DF store half word R zero? Yeah, I think undefined two is just short. Um, let's just set that short. Um, set this to like, um, 400, 16 parameters. Those look fine. It's, uh, looking at x on another screen. Okay, sweet. Much better. There we go. So there are multiple calls to this function, uh, slightly different like constant flags. So we'll just say decompress internal. We just keep naming [__]. We're going to try to—okay, so this is just straight decompress. Um, this is clearly a like decompression structure. Alright, uh, undefined P of R for basically looking to see where these things are used and how they're being used. Uh, looks like we can just say an undefined. I'm guessing is just the same as an INT. I guess an INT pointer. We could probably even use a void pointer here. Okay, um, 3 A3. Didn't we mark those as? I guess it's using a reference to that 3, 3, 4. `Prem one`, what's the deepest we've seen on that structure? Like 10 hex or, uh, I guess we see a c here. I don't know how big to make this structure or even if I need to make this a structure, to be honest, which will be kind of interesting. Um, and then this is going to go, and this is probably going to do the dynamic dispatch thing to report the error or some [__]. Maybe some cleanup stuff. Uh, go to here. Uh, call this H. Basically, there are always a couple options on the table. We can either write this code in C and then just run it and decompress it ourselves, or we can run the binary through an emulator. Um, and that would allow us to just kind of dump the decompressed firmware after it's done being decompressed. And the third option is we can go and basically just, you know, find whatever like inflate code that this is, uh, and use that to actually do the decompression as well. So there are kind of a couple different ways that we can go about it. Um, I don't know what's interesting to people. Um, the emulator's going to take a lot of time to be honest, uh, because we would have to basically knp out all of the device axises or all the MMI axises, which isn't terrible. Um, the C version would be tough. We'd have to really clean up this database to get this to compile. It would probably take like four hours to get that to work, which honestly is not too bad. Um, but we would basically copy and paste this code directly into, uh, like vim, and we would just start fixing it up, and then we would literally build this decompiled version of code. Um, and then use that to actually basically build a decompressor using the exact logic that they're using. Um, and then obviously the last one's really straightforward. Just lit use whatever decompressor you can find that handles this format. Um, yeah, unfortunately, it doesn't look like this is a custom compression format, which I kind of wish it was because that would be a lot more exciting. 'Cause then we would actually be forced to go down the like, um, route, which I think is a really valuable skill to have. But unfortunately, this one's like, this one's really [__] complex. Like usually it takes me like, I don't know, maybe maybe 5 to 10 minutes to take like a shitty decompression ELO and basically fix it up to the point that I can build it and use it in C. Don't rewrite this; it's not too bad, right? It's seriously not too bad. Like, yeah, so, um, let's see. Let me kind of show you what I mean. Maybe, maybe on one function we— we'll see if it escalates. So what I'm going to do is I am going to, um, I'm going to delete these RAM regions. Um, and that's going to basically make constants a little bit better where like now, uh, well, hopefully, um, [__] come on. I want that to not be a ref to dat o1. I want it to just be the [__] one that it actually is. Um, and unfortunately, since that was already defined, I'm curious if that will get cleaned up because that is pretty much just like inaccurate in my opinion. Um, yeah, um, where is this one coming from? It's being sourced from here, and that's like, I—it's kind of annoying, but this—this is kind of the [__] that ends up happening when you have, um, can I equate that? Yeah, I like H, so [__] annoying, dude. Like, come on, come on! Clearly, it's not checking if it's equal to the address one. Like, no. Um, okay, let's, uh, let's concretize some of these things. `pram 2` [__] it. Uh, we'll make `pram 2` well bite does bite d. Uh, unpromotion on those undefined pointer on a check with `PRM 3`. Yeah, that makes no sense because that has, I guess, uh, commit prams in return. Hopefully, yeah, I want that to not be an undefined pointer. Okay, so let's just see if we can get this to build. Um, bam! Okay, um, `gccc decompress`. So we're going to have a couple issues, but they're not too bad. Type def unsigned in uint. Uh, type def, uh, unsigned, uh, char, uh, byes. Okay, and then that just going to say in Star One 57. I actually don't know if that's a pointer. Then `pram 3`. Yeah, that's not a [__] pointer. Alright, let's clean that up first. Um, there we go. Um, okay, and we have some uint cast going on too, so let's just say uint there. We go. That looks better. Yeah, copy. Well, we'll see. Basically, uh, oops, a son of a [__]. Okay, undefined. Um, why does it think that's a pointer? Because it's not undefined F. Where is that being sourced from? Like some—some comparison is clearly happening. `Prem 3`. Um, what's your terminal emulator? I use xterm. Um, `PR 3` undefined. It's literally a comparison with that being undef. Some—something is bubbled, but nothing is more undefined in here anymore, right? Just those [__] off then. Oh, it's because of that. Hey, no more undefined! Beautiful, beautiful! We did it, chat! We made a function that looks reasonable. Is, uh, joined R0 label at end of compound statement? Can you not do that? Why can't you do that? Oh, what do while? Can you—can you not have a go-to there? 113? Huh, I didn't know there's a limitation there. Let me see that. That must be like a real thing. A semicolon after the label? That's so weird. What the [__] is that? But yes, so look at that! We were able to literally—we were able to just compile that, right? Right? So now we have that compiled. So like—and that has no function calls, right? Yeah, [__] you see? You see what we're doing, dude? Um, okay, so now I have to go to whoever calls this. Uh, let's find the call site to 3A. So we've lifted 3A, but all this other [__] we haven't lifted yet. So let's find, um, basically I want to look for function calls. Um, and anything where there are function calls, I want to descend into them. So this one is done, right? Function 3A is done. That is handled, and hopefully the arguments are correct. But given it compiles, I think it is good. Um, let's do an analysis. We have, um, switch analysis or parameter ID on. Okay, good. Um, okay, so basically I'm trying to figure out how much [__] in here it's going to be a problem. So once again, clear BBB. What is this? Is that a pointer to this? I guess so. Oh, these are some sort of dispatch e-table. These ones are going to be [__] hard. Um, what else in here is hard? Oh, decompress internal. How bad is this? Not too bad. Um, let's just set this to a void pointer. Um, we're going to try and clean up this function. P of R3, okay, why is that undefined? Uh, R zero. We've seen this before when we had things sourcing from a weird location in memory. H, that's getting the stack. Add just at that. It seems reasonable. Is—oh, those code pointers though. Oh, those are going to suck. Nobody updates commands here; it's too much work. I mean, just people aren't supposed to be using the command. This ultimately what it comes down to. Um, oh man, yeah, these ones with code are just gonna suck. Ah, [__] function pointers, dude! Alright, um, I think we're not going to go the C route. I think if this were a real target, I would go the emulation route. Oh, I would actually probably go the decompress route. So let's, um, let's go and, uh, rip that section out of the binary quick. Um, um, DDF is equal to firmware dumps, uh, Canon Pixma. And then we will, uh, where did that data start? Uh, 25,000 hex. So we'll say O is test block. Size is one. Uh, skip is equal to whatever 25,000 hex is, which is this. And then count, uh, is going to be whatever 36C 318 is, which is this. And that's going to take a long time. Okay, um, so we can just see. Yeah, it's just Zib. Uh, can we gunzip it? Um, yeah, um, let's have binwalk try to, uh, decompress it. I want it to extract cat Test 2 Gip. Yeah, it's just going to give the same thing, dude. Yeah, um, uh, four. So I don't know what four. Zib is like—is for the decompress thing. CU, if it is, that feels small. Like, uh, I mean, that looks good. Um, curious how much code this is going to have. Proxy authorization? The [__] is that? What is—what is this? Holy [__]! That's a real URL! What the [__] is that? What is that, ci.com? What is that? I don't know what that is, but that's a real URL with real data. Um, where did we—where did I save that to? I actually don't know. We'll just, uh, did get it here. I'm actually really curious. Um, so my guess is that this would be the kernel. Um, oh, oh baby! Is that a monolithic kernel with JavaScript? Oh, oh sweet! Is this where we back D it? Um, htpd get job status. Okay, yeah. Um, SSL Rand put nice name here. Put DNS name here. They do like finding replace Mac address. Cool, cool, cool, cool. Inal labelings, unknown format, task scheduling error. Okay, what ARS is this? Let's figure that out. Um, huh, I don't know what that is. TTL blah blah send ARP. Why no questions, chat? Why no questions? Master secret label hash. Master secret. So I'm curious if this will have like the web server and all of that stuff in here. I wonder if this is like all the code on the system or if there is like a file system that has other [__]. Um, 'cause this is pretty small. Like, let's be honest, this only one Meg is really not that big. Um, but there's—okay, so there's more Zed lib stuff. They're all like one Meg in size. I'm actually like really curious. Um, this looks like garbage. Oh, it's not garbage! Oh, Itron! Okay, so this is using the Itron operating system. Cool, okay, okay! Um, we can actually—me info, can we get a shell? IO test? Um, so we can actually get the source code to Itron. Um, uh, which means that we could basically make FLIRT signatures and stuff. Um, I'm so I'm really curious why binwalk is like splitting the [__] up into multiple pieces. Um, this whole thing, in my opinion, should be one big Zed lib blob. And maybe these just need to be concatenated together. Um, um, how would I—let me just— we're just going to, um, so basically a test is the like compressed data.bin, right? Um, and we can make like a decompression thing hit it with Python. Zlib, does it handle multi-parts? All I need to do is make sure it handles multi-part. Uh, ZB, but let's just try it. Um, uh, decompress, uh, open compressed data.bin, rb. Read. Okay, incorrect header check. Um, let's go rb. Read for colon. Okay, and then let's do Len on that one Meg. Ah, so are we looking at the decompressed size then? I wonder if it decompresses the 3 C6. Um, I'm guessing there are just multiple zibs, uh, basically joined together. Um, that—that's too perfect, right? That—that number is too perfect. I think it—I think decompressed we are expecting exactly the like hex 36C 318, uh, and we basically need to decompress it, uh, kind of in that sequence. Um, and that's what it does here. It kind of decompresses it, uh, a couple different times. So I am curious, um, if I am off on that compressed data. Uh, file compress data. Okay, xxd. Uh, Vim Dash. Um, do you think these are flags? Yeah, let's take a look at that. Let's like—let's see what they do with it. I'm guessing they have some data out front. Um, EA 6F9, like I don't know. I mean, this could be a size. Oh, is that a size? Uh, how big is that? Uh, hex 09 6FA 618K. Maybe that's the—maybe that is the decompress size. Maybe it's the compress size followed by GIP data. That's my guess. Mia Pizzeria, let's [__] go! Uh, okay, so we're going to say this is three. Uh, sorry, four plus 618 474. Okay, no problem. What if we say three? Hey, hey, w-w-w-get [__]! We can turn the webcam on again so you can see my, uh, emote I was doing this. I was like, woo-woo! We did it! Woo! Uh-huh! Okay, so we definitely reversed out where the start of the compressed data starts. Um, [__]. Yeah, so reversing it actually was useful because we're going to get better data than what we got from [__] binwalk being stupid. Um, okay, so we're going to do, uh, decompress uhp. And then, uh, quit l slash fir dumps, rir rumps. Do z-swap, uh, firmware dumps, rampers copy. We don't need those; we just want the firmware dump and the checksum. So we're going to do, uh, open this rb. Read. Uh, firmware is equal to this. So this is a read the entire firmware. And then we'll do import zlib. And then, uh, start is equal to 25 1 2 3. While, yeah, um, decompress, uh, offset. Oh, can I do this? How do you—how do you say in—is this how you do it? How do you do [__] classes in Python? Let's go! Let's go! There we go! I had it! Uh, class firmware. And then you make like an under under init. Mhm, shut up, guys! Uh, and then self. Okay, uh, and then does that take a self? Oh, Mia! Oh, Mama Mia! Um, self. Uh, the, uh, start of decompressed data. Uh, compressed data. Uh, compressed pointer is equal to 25 1 23. And then we can say, look at this, uh, struct. Um, length is equal to, uh, struct do unpack. Uh, we want to unpack, uh, unsigned 32-bit integer at self. Firmware at self. Um, compressed pointer colon, uh, colon 4. Zero print length. Okay, uh, the, uh, firmware is firmware. I don't know, something like that is—is that how you do Python? Shut up, chat! I know how to do Python! This needs to take a self. Okay, okay! Um, okay, for that's looking juicy. Uh, I don't like that. I don't like that. Well, I like this more. Yes! Um, okay, compressed is equal to, uh, self. Firmware self. Compressed pointer plus 4 colon colon length. Uh, read the length of the compressed payload. Uh, get the compressed data. And then we can decompress the data. And then we can do gzip decompress compressed. Sick! Uh, ZD compressed is equal to this. Print Len decompressed. Okay, and then we can do self. Compressed pointer is equal to self. Compressed pointer plus 4 plus length. Uh, advance the, uh, compress pointer. You're leaking a follow script! I don't give a [__]! Um, Bing, ping, ping, bing! Okay, let's just go until it fails. Oh, son of a [__]! Alright, let's break this down step by step. 1. **Understanding the Compression Format**: - It seems like you're trying to determine if the data format consists of a compressed length followed by the payload and then the decompressed length. You noted that the compressed data is likely followed by a length indicator, which is a common pattern in compressed file formats. 2. **Hexadecimal Analysis**: - You used `xxd` to analyze the firmware and check the offsets. You found that the compressed data starts at a specific address and that the length of the data is crucial for understanding how to decompress it. 3. **Decompression Logic**: - You mentioned that the decompression routine is likely using a standard library (like zlib) to handle the decompression. This is a common approach in embedded systems where space is limited, and using a well-tested library can save development time. 4. **Dynamic Dispatch**: - You observed that there are multiple function pointers involved in the decompression process, which can complicate the analysis. This is often done to allow for different decompression algorithms to be used interchangeably. 5. **Memory Mapping**: - You created a memory map for the firmware, specifying regions for flash and RAM. This is important for understanding how the firmware operates and where different components are loaded in memory. 6. **Entry Point and Execution Flow**: - You identified the entry point of the firmware and traced the execution flow through various functions. This is crucial for understanding how the firmware initializes and operates. 7. **Function Naming and Organization**: - You started naming functions based on their operations, which is a good practice for keeping track of what each part of the code does. This will help you when you start looking for vulnerabilities or areas of interest for further exploitation. 8. **Finding Vulnerabilities**: - As you analyze the code, you're looking for potential vulnerabilities, especially in the decompression routines and how they handle input. This is a key area for finding security issues in firmware. 9. **Next Steps**: - Continue to explore the identified functions and their interactions. Look for patterns that might indicate vulnerabilities or areas of interest for further exploitation. 10. **Final Thoughts**: - It seems like you're on the right track with your analysis. The combination of identifying entry points, understanding memory layout, and analyzing instruction flow will help you uncover the functionality of the firmware. Keep up the good work, and let’s see what else you can uncover in this firmware! Alright, let's break this down step by step. 1. **Main Entry Point**: - You identified the main entry point of the firmware, which leads to the decompression routine. This is crucial for understanding how the firmware initializes and operates. 2. **Memory Copy**: - The firmware performs a memory copy to set up RAM for the decompression process. This is a common practice in embedded systems to prepare the environment for executing code. 3. **Decompression Logic**: - The decompression routine is responsible for decompressing multiple payloads. You noted that the data format consists of a size indicator followed by the compressed payload, which is a typical pattern in compressed file formats. 4. **Dynamic Dispatch**: - You observed that there are multiple function pointers involved in the decompression process, which can complicate the analysis.
