I don’t have particular experience with firmware hacking but how would you achieve persistence with just a simple malloc/bad malloc replacement? What if user decides to reflash the ROM during runtime? I imagine persistence would require emulating the entire firmware update process.
In order to emulate the firmware update process, you would need to reverse engineer a large portion of the binary, right? This is where LLMs would be helpful.

- DethNinja 4y agoThat is exactly what I’m saying, a specialised LLM can reverse engineer and analyse the entire firmware / firmware update process faster than a human and thus automatically implement malware for all kinds of devices without access to source code.
- l33t233372 4y agoNot to be a dick, but I don’t believe you. Show me, if you can. Edit: if you mean that theoretically this may one day be possible for a LLM to automatically hook functions and introduce persistent malware, then, not being a future teller myself, I would likely agree with you. But that’s not interesting because you can say that about essentially anything.
