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.

Any base64 string passed to python via cmdline should be considered as HIGHLY suspicious, by default. Or anything executed from /tmp, /var/tmp, /dev/shm.

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

if @op would have had Lulu or LittleSnitch installed, they would probably have noticed (and blocked) suspicious outbound connections from unexpected binaries.

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