On installation or importing, the package attempts to exfiltrate some basic information, e.g. /etc/passwd

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: 2025-06-atlasctf

Reasons (based on the campaign):

  • exfiltration-generic

  • The package contains code to exfiltrate basic data from the system, like IP or username. It has a limited risk.

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