Introduction to Firmware Reversing

[@tomdoughty1577]

You know what I loved about this video compared to others? You were quick and straight to the point. Brilliant video, thank you!

[@shaunclubberlang2887]

I agree. Excellent video

[@avramitra]

Exactly!

[@WoWAuctionsnet]

Yeah, explaining too.

[@rodricbr]

thats not the point, the thing is to understand what it does and its functions

[@sinistergeek]

Exactly

[@tonygambacorta651]

Wow! I was wondering what all the YT notifications were about...then opened /r/reverseengineering and saw my video. Many thanks to everyone for the kind words- definitely inspired me to start cranking out content again. And sorry about that bad blog link that was in the description- fixed.

[@YuGoCheff]

You're such a great teacher Tony! More content would be awesome :)

[@helgesverre]

Would love some more videos :)

[@danielleal7999]

Hey Tony, I liked your video a lot and so I subscribed your channel. I'm currently working on a translation project and we need to reverse engineer and translate a firmware file, the extension is quite weird ".fw". Do you think you can have a look and give me a quick hint on what I can use to extract or edit this file? Here's the link: drive.google.com/open?id=1rF26ql5oewQYBgl1HL98FK0brspiW_Xu

Mate your the fucking bomb. I’m showing my employers how “out of date” their new shit is and how exploitable it is.

[@AllanAquinoVieira]

YT has just recommend this video, and this is by far one of the best tutorials that I have seen. Straight to the point, not wasting time explaining the basics at a nice place and eloquently narrated. Please post some more interesting videos, even if explaining the basics. YT needs more content like yours.

[@miigon9117]

The thing that’s great about his video is that he not only tells you how to do it but also tells you the thinking process, while still keeping the video short and straightforward. He’s a great educator. I hope my teachers are all like him.

[@miigon9117]

2 videos and 10k subs already, that’s the prove.

[@miigon9117]

Wow near 40k subs already!

[@dienadel30]

"The quieter you become, the more you are able hear" love that quote. Great video !

[@cryptographics9647]

Loved the enthusiasm despite you probably having done this a million times. inspiring

[@tocraft573]

This guy is an absolute genius, the video layout, explanation, its all too good to be true

[@davidking2490]

Your conversational tone with the computer makes it very easy to understand. Thanks for enlightening us!

[@LuckyST]

you are one of the best teachers and explainers I've ever seen online. Your pace is excellent, and your pauses for in depth explanations are just when and where they should be! Please continue making videos! this channel is pure gold ! I got here by accident... and had no intention of reversing firmware and UART hacking, but now I want to!

[@bencesarosi7718]

This is top quality material, really. Even though I'm familiar with 99% of what is presented here, I literally enjoyed every single second of it. Thanks for your time!

[@ruhnet]

Agreed

[@AWriterWandering]

Only two videos on this channel, but both of them are absolutely awesome.

[@LaneLarson]

Great video! I used it to reverse firmware for an NVR years ago, and I've come back to watch it several times again recently.

[@johnsmithking]

Your positive way of talking is a thrill to listen. You’ve made my day 🙏

[@damienclark7163]

I finally found a place on my level! I'm just learning this stuff. I'm building and working on esp devices with mqtt. Now burning chips. My normal profession for 23yrs is low volt work like access cctv etc. I subbed right away. Amazing teacher!

[@ForcefighterX2]

Best video of expert IT knowledge I have ever seen in my 20 years of being a software engineer.

[@PhoebusG]

Can't believe you only have two videos... get cracking, you're awesome!! Also an idea, maybe a twitch channel for live stuff. You can then edit highlights to youtube :)

[@platronic]

youtube recommendations makes me cry because there's no new videos from this channel

[@evanlord2280]

ya same hello

[@stevrgrs]

Bro. How do you only have two videos and nothing new. You’re great at teaching and explaining stuff ! :)

[@chillappreciator885]

Two years later Google decided to recommend this video) Great job Goo)0)

[@jonjimihendrix]

I learned more in this 11 minutes than I have in years of tutorials

[@micmacha]

This is the best KZbin channel I've bumped into in a long freakin' time. Thanks for doing this!

[@caritas3015]

Just caught your site by chance and super glad I did. Fantastic communication skills, you are hands down the best narrator I have ever heard for this genre. Usually, those "in the known" are, well, just dry and nerdy and have zero vocal skills. Love the banter the delivery, that coupled with the obvious mad electronic and programming skills you are a phenom in my book. I subscribed in the first minute. Keep them coming and I will look for your patreon info next. Thanks

[@isaackay5887]

*_By far...my most favorite reverse-eng. tutorial_*

[@webwolfy7310]

Wow, I can't tell you how immensely useful this has been! I have like two sheets worth of notes here :).

[@SimpleLangSolution]

It is a common tradition to come back to this video once or twice per year.

[@manuyel4845]

Hope he comes back with new videos someday

[@moardub]

Dang where can I find more content like this? The presentation style and learning experience from this are top notch!

[@damienclark7163]

Share this on the right channels man. I so want more. You teach well in comparison like network chuck

[@michaeljburt]

This is an absolutely brilliant demonstration. I learned about 20 very useful and interesting things there.

[@AutomaticGamess]

@Tony Gambacorta, could you make a video explaining how to re-pack the file-system back into the firmware after making changes to it?

[@needausernameJesus]

Tony, I only see two videos? are you going to do more? I really liked this and inspired me to do this project. Hopefully you have more videos and I looked in the wrong library. All the best. Just subbed

[@S0L4RE]

Please make more of these videos!! I love how straightforward and to the point they are!

[@1malditoPerro]

I wish you would have found time to keep the videos coming. That would've been been great.

[@pepe-perez]

man you should be a really good trainer, the flow of how you teach is the best.: iintro/overview - steps - ending/recap.

[@WistrelChianti]

+1 for the academic sandwich. Superbly explained and great style. Very interesting video

[@HackingIsDope]

just one word WOW, it was really beginner friendly and to the point!!!!

[@bluegizmo1983]

You should be making more videos like this. Very informative and to the point!

[@MrNightowl1980]

Love this video and the way you explained it. I followed along and opened a new world for me. Thanks so much!!

[@teddysoft]

YT said this video was right down my alley, and heck yeah 👍! Did learn a few new things! Best regards Ted

[@kvykimo]

youtubes algorhitm recommending a 2 year old video to everyone again

[@dexterlazer5854]

because it's great

[@joshsitter-konishi2324]

Yeah, I was thinking the same thing but I still do this with my Kali for work so still rather relevant even some of the tools are a little different. Still gave him a thumbs up. Looked if he had more content and was sad that there wasn't.

[@ytcer]

Is that a problem? I came here voluntarily cos the other vid was wicked.

[@anteconfig5391]

That's nothing. I've been recommended 6-8 year old videos a couple of times already.

[@v.gedace1519]

Why not? And: The YT algo figured out that the video content is still relevant. ;-)

[@AbdelrahmanRashed]

I learned more in this video than my entire life on firmwares :D

[@adrian3k]

Great peace of information, new in fun with extracting firmware to check some configuration I need in my project :D

[@socat9311]

With consistent uploading you would be in million views easily. Really good stuff mate

[@dmytromykhalko4001]

It's just an amazing video! Very thanks to the author for sharing his knowledge, it's super useful and clear. Really appreciate your work!

[@adamarzo559]

Awesome video. Hope you come back and make another one, you are very informative with how you explain!

[@michaelmoore830]

What an excellent video. I would buy an online course from this guy in an instant. Good pacing. No nonsense.

[@maxneumann]

The way you are explaining is just amazing

[@Sunomis]

Great content! I'm shocked that there's only one of those. All the more precious I guess ?

[@ricseeds4835]

This channel needs more videos

[@BoZmD]

Love the summary at the end! Nice.

[@sevendesign1805]

Please come back with more content! MORE PLEASE!

[@Dabbo07]

A really well presented and put together video. Not something I'll ever do myself, but it was interesting to watch.

[@slano8850]

Thanks to KZbin algorithms,I’ve learnt something incredible today. Great video man

[@newrind]

I hope this is just a start.. Looking forward to see more videos! Thanks

[@evidencemonday5948]

Awesome video. Please can we have more of this where we can use ida or ghidra to analyse the services running on the firmware?

[@SimpleLangSolution]

I miss you Tony. Please come back.

[@imperia777]

I was going to insta subscribe, but saw you have only one video. Bring up more content. This tutorial was excellent

[@oussamathedjfreeman]

Great video, thank you! You will kick it on YT because your style is easy going and your easy to follow among with. Seems suggested video is pushing it so hopefully it's the first of many 👍

[@kenerik]

Oh.. we need more of this stuff... 🔥🔥🔥

[@akhileshb_]

Dude seriously make more these please.

[@AxelWerner]

This is one of the most beautiful tutorial videos ive ever seen!!! from zero to hero in 11 mins (feels like just 2mins). and the fun thing is, i do have the exact same cam and model ^-^ double fun to learn more about it by looking into its code. - btw: did i see a shellscript building a linux passwd file (user accounts/maybe passwords) from NV RAM content ?! VERY interesting!!! PLEASE!!! MORE!!!

[@thetiredtechie2704]

Short and sweet - looking forward to more!

[@shifter65]

This video sounds like its part of a larger series... Is the rest available somewhere else?

[@sevendesign1805]

Seriously, his KZbin account only has two videos. One from 2 years ago and one from 2 weeks ago. His content is superb but, unfortunately, inconsistent.

[@johnson554671]

You're smart and good with Linux! Thanks for your tutorial.

[@fernanmateos]

Fantastic couple of videos, man. I am subscribing in case you decide to do some mire at any moment in the future.

[@nowave7]

With the latest firmware, the unlzma of a kernel.lzma image reports corrupt data. file also reports a different original binary file: DCS-932L_B1_v2.18.01.bin: u-boot legacy uImage, and the structure is, according to binwalk also different, with uImage at the address of 0x0. Also tried the original version that was used an example here, but the same thing happnes. Any thoughts?

[@chidaruma_]

Quality content!

[@tacolover619]

What happened to (Host) Tony Gambacorta?

[@demianxldc]

hi, you can repack that .. to customfirmware?

[@PyPylia]

Most likely, watch this video he does a similar thing and it should be roughly the same process for both: kzbin.info/www/bejne/noebiGelYrKoaNE

[@fh404]

@@PyPylia some devices however check for a cryptographic signature when flashing a user defined binary. Which goes just against everything Linux and GPL is all about :(
