Source: kam193 (bc1ea66b7bd97f1590f64319f168a1e5ce5f257bf47595de26247cc07a48f80c)

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 (478842d7ed3add19d4538dfb29bfa4bdc5fe0b85bac64d24446a37a5dab9dbcc)

The OpenSSF Package Analysis project identified 'blab111' @ 0.0.1 (pypi) as malicious.

It is considered malicious because:

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