Intro to Hardware Reversing: Finding a UART and getting a shell
885,107
Published 2019-11-04
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 :)
-
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.

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.

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!

Bro, i was watching it WITHOUT SKIPPING, it was so cool and interesting! Sadly, there are only 2 videos on your channel. Make another one, it's really cool. Pure jewel.

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

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!

This is one of the most informative videos I have ever seen in my life. So much info packed into such a brief video. This guy should be teaching IT professors how to explain things.
-
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
-
Doing my yearly attendance to this wonderfully made video. Please come back.
-
You made learning this fun and entertaining. A professor once told me that a true sign of intelligence is the ability for a human to make a complicated task sound easy and enjoyable to enable another human to learn the topic covered.

"we're not disarming a nuke", combined with some hours watched on louis rossman and the current ongoings in eastern Europe, and the algorithm does its work and here we are. great video, thanks :)
-
I rarely comment on videos, disappointed there aren't more. Easy to follow, perfect pace. ty
-
I learned more from 2 videos and 20 something minutes than I have done in years from other sources 👍🏻
-
You sir are a good teacher of the uninitiated. Being able to bridge the gap from uninitiated students to intermediate learners in fields like IT/Network Inf is crucial! Make more videos please!
-
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 :)
-
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
-
Such cool stuff. I’ve been so scared of hardware as I’ve been a software guy for so long. It’s neat to get my feet wet watching these and soon to play. Thx.

Please continue to make more videos if possible for you. You stand out as one of the clearest communicators I've ever heard from in Cybersec
