angr VS frontier-silicon-firmwares

That's awesome! That's exactly how modern decompilers deal with a special type of goto occurrence. They reduce gotos (or completely eliminate them) by introducing a `while(true)` loop, followed by corresponding `continue` and `breaks`... we all, of course, know that `while(true)` did not exist in the source, but it's a nice hack!

We even do this in the angr decompiler, found here: https://github.com/angr/angr/blob/8e48d001e18a913ecd4ed2e995...

One would hope browser and OS vendors would use AI to remediate vulnerabilities but vast majority of software vendors won't ever use it.

Also, automated vulnerability finding is very much real and already used today. This isn't something that has just become viable via LLMs, but I guess LLMs can enhance it:

BAP (https://github.com/binaryanalysisplatform/bap), angr (https://angr.io/) and others already do what you're asking for as more purpose-built solutions for dynamic analysis. Angr specifically in python.

As /u/hkei noted, it's actually quite difficult to do in general, and usually requires some kind of heuristic. For example, see https://github.com/dyninst/dyninst/blob/v12.1.0/dyninstAPI/src/image.C#L476. Full disclosure, I am a Dyninst developer. There is also the python-based angr that might be more amenable to a one-off solution.

I think there's a lot of promise in automation that's been spun off from the CTF community. Angr and Binary Ninja are both very much spinoffs from contest hacking, and are pretty great for helping a skilled hacker find flaws in software.

angr uses z3.

Supposedly, the DoD has used angr for some use cases.

Hi I had look at the update.py script mentioned from https://github.com/cweiske/frontier-silicon-firmwares It works on the basis you have the .bin files in the same folder as the python script and decodes from the file name, the in Product, model and version number. If you don't have the files it does nothing. I don't have the files and when attempting to query the update server you need a previous version. I tried the following https://update.wifiradiofrontier.com/ns/FindUpdate.aspx?mac=305990119F32&customisation=ns-mmi-FS5332-0000-0007&version=1.0.40-30-30 But this returned an error or no page. Thinking the update query server is down. I then went and wrote a little python loop hitting the file server, which I found by some tricks, And incrementing ns-mmi-FS5332-0000-0007_1.3.18-43.ota.bin to ns-mmi-FS5332-0000-0007_1.3.18-44.ota.bin to ns-mmi-FS5332-0000-0007_1.3.18-45.ota.bin Until I hit 2.0.00-00 I did a loop from 100000 or 1.0.00-00 until 200000 or 2.0.00-00 Found the following bin files to download
