Summary
Malicious code in benign-lib (PyPI)
Details

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

Source: kam193 (09477b048d84611002417894ccb3265d246be0156b096a8b47776960d45e9d3d)

Package hides an executable inside, and starts it when imported. The sandbox analysis shows only starting a calculator, which suggests it's a research attempt without a big harm.

Category: PROBABLY_PENTEST - Packages looking like typical pentest packages, but also anything that looks like testing, exploring pre-prepared kits, research & co, with clearly low-harm possibilities.

Campaign: 2025-10-benign-lib

Reasons (based on the campaign):

  • malware

  • obfuscation
