Summary
Malicious code in packed-w3shi (PyPI)
Details

-= Per source details. Do not edit below this line.=-

Source: kam193 (3d670904891ef361ef283e3f218f21b6e3758847277e8bccb0dbecd08b08971a)

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.
