Drone Hacking Part 1: Dumping Firmware and Bruteforcing ECC
- nerdsniper 9mo agoWhat a beautiful write-up! This is such a lovely resource for anyone who ever has the curiosity of "I'm interested in getting a firmware dump".
- purplehat_ 9mo agoFor anyone else who got a little too excited at the title, ECC here is error correction codes, not elliptic curve crypto. Very cool writeup, thanks for digging into all those data sheets and sharing it with us! I feel like the hands-on electronics stuff has always been a little bit inaccessible to me, but posts like these always make me a little more excited to start doing little projects myself. So thanks for posting.

- eimrine 9mo agoWhat a laugher, of course it is not like that. Especially funny sounds the return to base function. Multi-frequency communication, a lot of retranslators making you to be able to fly inside of caves, refusing to use Starlink in the areas having a bleeding-edge anti-starlink antennas deployed. Or just receiving Netflix-grade picture from the optical cable while reducing to zero anything emitting radio-signals.
- aenis 9mo agoFantastic and inspiring write up, big thanks! Here is to hoping someone will do something similar for DRM'ed BOSCH ebike motors.
- stavros 9mo agoBe the change you want to see in the world.
- mschuster91 9mo ago> Here is to hoping someone will do something similar for DRM'ed BOSCH ebike motors. Please not. Bike thieves are already annoying as they are (a ring in the rural city I live in managed to steal over 400 k€ worth of bikes in a matter of months, in my case they only stole the control unit), and so are people modding their bikes to run (way) faster than the legal limit, leading to more and more calls for them being banned off of normal bike tracks.

- gessha 9mo agoIs people stealing bikes and parts a technological problem or a people problem?
- Palomides 9mo agoyou could compare with apple locking down iphones and parts, which I understand significantly reduced theft
- IshKebab 9mo agoI seriously doubt any kind of DRM is going to dissuade bike thieves. It hasn't really worked for phones has it?

- mschuster91 9mo agoAnd as usual... something that looks like it uses Linux, but has absolutely zero Google search results on how to obtain the GPL sources. We desperately need some large ass legal fund that takes the GPL violators to court.
- smokel 9mo agoIf they use unmodified Linux, then they only have to provide (a link to) the source code to that kernel on request. No source code is required for proprietary add-ons, unless they are kernel modifications. The GPL also does not state that the source code should be easy to find. In the early days, one had to write a letter, send it by mail, in hopes of getting a tape or CD-ROM with the source code. For which you then had to pay as well.
- wuschel 9mo agoWhat could be the potential risk of not being compliant to the software license at hand e.g. let us say we would sue a GPL violator?
- ofrzeta 9mo agoThere have been several trials, all of them won, I think https://gpl-violations.org/about/ https://gpl-violations.org/about/
- MPSimmons 9mo agoDamn, I really enjoyed reading this. Great writeup!
- vachina 9mo agoNow do DJI next
- Neywiny 9mo agoGreat work. Seems like a typo when covering inversion. They claim parity(0) = 0 but still use the equation with != from before. It's nice to see that they, like me, subscribe to "an hour of experimenting can save 5 minutes of reading the documentation." Of course what people often fail to realize is that until you've found the answer, you often don't realize what the documentation was saying, such as the 16-bit thing. Management may ask "was that not in the manual?" But it's more nebulous than that.
- gessha 9mo agoI bet you that one hour was full of excitement, where’s the fun in reading the documentation :P Another great to look at it is possibly as a TDD approach vs analyzing the problem at a deeper level.
- dextrous 9mo agoThanks very much for this awesome write up! It’s detailed labor-of-love work like this that helps others (like me!) make great jumps in learning. So appreciated.
- syntaxing 9mo agoFun read! How long does the script take to run? I’m curious if you would have noticed any performance increase if you wrote it in C++.
- duttybear 9mo agoBruteforcing ecc is the Services may subject to the contrary. My vision of brutforcing is droning below sea levels, .
