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 (4d5397bb157f48b8104cfb11a88215fb953c075bb43fdeceed3f1bbec8af96d5)

The OpenSSF Package Analysis project identified 'torchunmix' @ 0.2 (pypi) as malicious.

It is considered malicious because:

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