Malicious code in ctftestsowwy (PyPI)
Details

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

Source: kam193 (d6e53c512e63c328ecdc02187c5fe11c5b379e6bf451f936f769219c1787d146)

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.
