Summary
Malicious code in researchpoc (PyPI)
Details

-= Per source details. Do not edit below this line.=-

Source: kam193 (20a5e6f7ec432b0c41646f696c530fb5e46e034477a23d448de1ac3f18172bec)

Package mentions being a research PoC, probably for dependency confusion, but the code is obfuscated making verification of the claim impossible.

Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers.

Campaign: GENERIC-questionable-pentest

Reasons (based on the campaign):

  • exfiltration-env-variables

  • exfiltration-generic

  • The package overrides the install command in setup.py to execute malicious code during installation.

  • typosquatting
