The user identifies themselves as a HackerOne user abusing the PyPI for the purpose of a bug bounty program. 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-hackerone-bugbounty Reasons (based on the campaign): - dependency-confusion - The package contains code to exfiltrate basic data from the system, like IP or username. It has a limited risk.
