angr VS qiling

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:

Check out angr [1], a symbolic execution engine, and claripy [2], its frontend to SMT solvers like z3.

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 - Platform-agnostic binary analysis framework.

angr uses z3.

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

Try using angr to automate bug finding

Sounds more like r/ReverseEngineering. If what you want to do is some dynamic analysis or just play around, maybe try using qiling, it's built on top of unicorn and is made by the same authors. It will take care of loading the file for you.

https://github.com/qilingframework/qiling Is probably what you are looking for

It is s binary emulation framework, which you can use to emulate different binaries for different architectures. On top of that you can use Qiling APIs to debug the emulation process, hook syscalls, etc. It's like Unicorn + Qemu + Frida. More info here: https://github.com/qilingframework/qiling

qiling is built on unicorn directly. qiling focuses on emulating binaries (read: emulating a single program and not an OS). It uses the binary blob work to load binaries and their associated shared objects. It then hooks the OS calls and presents an interface to the program as though it has interacted with an OS. see here

We started this project since 2019 Nov, currently they are around 70+ developers and 2,200++ stars in our Github page (https://github.com/qilingframework/qiling)
