Packages that might be part of testing for pentesting / malicious activity / joy, with suspicious activity that does not present any real harm.
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-simple-tests
Reasons (based on the campaign):
- The package overrides the install command in setup.py to execute malicious code during installation.
