Intro to Hardware Reversing: Finding a UART and getting a shell

This video is part of the Figurable project, which is geared toward people who are curious about IoT security and looking for that first bite of the apple.

If you're interested in hardware but haven't had a chance to play with any yet, this one's for you. In this "hello world"-level reversing project we're checking out a UART (serial port) and using it to access a shell on a *very* soft target. If you decide to try it on your own you'll find an equipment list, walkthrough references, and some troubleshooting ideas at the link below.

The rare 'triple crown' of educators: Intelligent, good at explaining, and interesting to listen to. Props.

Dam I was excited to watch all the videos but I just realized that there is only 2 of em. Please make more videos I love them :)

My bro released one of the most cool videos out there and just vanished😭

6:11 Serial ports usually default to the high level when not transmitting and pull the line low to send the start bit (0) after which it jumps up and down to representing the zeros and ones being sent. While transmitting data, on average the line is usually somewhere around half VCC since on average you'll probably be sending about as many zeros as ones. Therefore you should expect to get 3.3 V on idle around 1-2 V while transmitting. That's with a multimeter (or other slow voltmeter), on an oscilloscope you would see the actual data being sent of course.

Please don’t make us wait another two years lol

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.

[ohnoitisnt]

Thank you for listening to your new wave of viewers. You have a knack for videomaking and this is a hella cool topic thats massively underrepresented here on youtube. Keep this thing going!

[MyNameIssaSimon]

The youtube alg is in your favor, did you reverse engineer that too? 😬😂

[iw]

Imagine dropping 2 banger videos, 2 years apart, and then disappearing for 4 years lmao

[annix]

Tony! There are only two videos here?! I refuse to believe that you have this level of skill as a teacher / producer of tutorial videos out of nowhere. Please, PLEASE, if you have some back catalogue of videos that you’ve produced for work/school?

I am 100% certain that I speak for every sentient life form across the known and unknown universe when I say :

TONY.
GIVE. US. MORE!

I don’t care if it’s a video showing us how to bend a paper clip to look like a bunny. Teach me to clean a soldering iron by licking it. Show me how you organise zip-ties. ANYTHING, TONY. PLEASE!

I should thank you for the FCC thing you thought us. Thanks

Im an electrical engineer by education and a software developer by trade, and this video is a beautiful rainbow connecting them both. Can't wait to mess around with some of this stuff

[Linux.Learner]

SPEECHLESS. PURE JEWEL. It takes great curiosity, comprehension and an intelligence to cram up the most difficult of the contents into as much less of a time and length as possible - with added wittyness. THIS MAN IS A TRUE GENIUS. A man holding the capability to spark the same into others. BRAVO! BRAVO! BRAVO!

You should definitely make more of these. No doubt they're time consuming but you seem to have a knack for it and a voice people want to listen to. There's also not a too many people making content specialised in electronics on YouTube at the moment. Given the response you've had so far I'd say It's quite a good opportunity you've got here not to mention a nice way to earn a bit of cash on the side.

Hey, just checked your channel and im disappointed its not a gold mine of more content just like this. Im a senior electrical engineer going for a masters in elec/computer engineering and this type of stuff I wanna learn to do its incredibly interesting and hope to see more in the future. Great stuff honestly

[LyddonGareth]

I rarely comment on videos, disappointed there aren't more. Easy to follow, perfect pace. ty

[frankdurso]

This was really good. I'd really love see more content like this!

[dgramop]

I once found a serial connection on a chinese smartwatch. Ended up getting a boot prompt for the mediatek chip that was on it

[benjelum]

hands down some of the most incredibly approachable, beginner friendly, and informative content I've ever seen on the subject!

wish you were still making videos :)

[raspberrynode]

If your goal is to put up a video every 2 years I assume I speak for most and say 'no problem we'll wait'... but you're a bit over due -) nice work
