Probably one of the best things about AI/LLMs is the democratization of reverse engineering and analysis of payloads like this. It’s a very esoteric skill to learn by hand and not very immediately rewarding out of intellectual curiosity most times. You can definitely get pointed in the right direction easily, now, though!

In this case, this has nothing to do with reverse engineering, it's basic system administration.

See how the AI points you in the "right" direction:

  What likely happened:
  The exec(base64.b64decode('...')) pattern is not malware — it's how Python tooling (including Claude Code's Bash tool) passes code snippets to python -c while avoiding shell escaping issues.

  Exfiltrates data to https://models.litellm.cloud/ encrypted with RSA

Having said this, uploading a binary to Claude for analysis is a different story.

I’ve entertained myself with CTF walkthroughs on YouTube before and had been meaning to try it out. But yeah I feel it falls under the same category as lock picking, fun to LARP, unlikely to stumble across in my day job.
