Show HN: Hexora – detection and analysis of malicious Python scripts

3 points

9 months ago

I made a new library to detect malicious and harmful behaviour in Python scripts. It uses static analysis with semantic modeling. Even when the code is pretty obfuscated, it can still detect it.

For example, it can infer that

    getattr(sys.modules["built"+"ins"], "".join(reversed(["al","ev"])))("1+1")

Is basically:

    eval("1+1").

Currently, I'm testing it on public files where some of them implement malicious behavior, as well as past malicious packages on PyPI.

You can see some of the detection examples here: https://github.com/rushter/hexora/blob/main/docs/examples.md

I'd love to hear your feedback and ideas on how to improve this and identify missing rules.
