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.

Reasons (based on the campaign):

 - The package overrides the install command in setup.py to execute malicious code during installation.
