Source: kam193 (bebd39f4de86af5e9634fbfda5f8c97794b597b1066c2fcd32e3a2068569280d)
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 (4335bf56e5be8695fa87d7678b21eb5080d33a35c0c0f6b0278a4555ae5b1f2a)
The OpenSSF Package Analysis project identified 'testing123kk' @ 10.0.5 (pypi) as malicious.
