hyperswitch VS angr

Similarly there is https://hyperswitch.io/ open source written in Rust.

Lago is written in Ruby.

I found few others opens source billing systems written in Java.

Anyone knows anything written in nodeJS?

🚨 BTW we are hiring for several roles, apply here.

Ultimately, we believe that payments should be a basic utility like water or air. This is important because the payment ecosystem is full of closed systems and walled gardens. It is also extremely diverse (as it should be). In order to enable this diversity, payments need a trusted unifier like Linux. The road to commoditize payments will not be easy and we are looking for engineers that can make it happen. If this vision resonates with you, consider applying for Hyperswitch and we’d love to work with you! 🌟🔧🌈

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 uses z3.

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