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.

Source: ossf-package-analysis (e440f8eb662e7ce167b261bb84b822226ee7bfc8348cbcf3db8e8a65d4dd7825)

The OpenSSF Package Analysis project identified 'packagemurder' @ 23.99.0 (pypi) as malicious.

It is considered malicious because:

  • The package communicates with a domain associated with malicious activity.

  • The package executes one or more commands associated with malicious behavior.
