Source: kam193 (999886fcc5bada14ab742719f34eef0d929a1319b6011060b7e13e1598c292f0)

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 (6d8ae54694435d049b0d7f0a1e37c940dd35b30ea4c50f51f1ec3c9d1390f38e)

The OpenSSF Package Analysis project identified 'osopackagepy' @ 10.0.0 (pypi) as malicious.

It is considered malicious because:

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