Source: kam193 (2d88bf5533b182da36c514791c3e6841d83565d4d7f7065a09cdebddc2509453)
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 (de8fcd89ceac4710fb35902553838b859dfcfcee125fb2abea28362019be0ce9)
The OpenSSF Package Analysis project identified 'faker-python' @ 999.0.0 (pypi) as malicious.
It is considered malicious because:
- The package communicates with a domain associated with malicious activity.
