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 (7a632d46c9cda2dc51b4f8dabb8860c8bed1f5c0250dc785770b881f6b88c4d6)

The OpenSSF Package Analysis project identified 'subdomainer' @ 1.0.0 (pypi) as malicious.

It is considered malicious because:

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