Details

Source: kam193 (24a23931f60d9a2daf27a6df2eff2f3102cb239f6d058bed6646d208787f0c5b)

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 (1bb9649abbc3c57b35f0f247886a0b50587f752f3cf5707db3a57e85502d40f2)

The OpenSSF Package Analysis project identified 'tabformerlite' @ 99.0.0 (pypi) as malicious.

It is considered malicious because:

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