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.
