Source: kam193 (05bfc8616802c80804de7998c57d6b1f62deff849f9d3545b0775edfcd0de264)

Installing the package or importing the module exfiltrates basic information about the host, and the package has no other purpose.


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: GENERIC-standard-pypi-install-pentest

Reasons (based on the campaign):

  • 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.
