The user identifies themselves as a HackerOne user abusing the PyPI for the purpose of a bug bounty program.\n\n\n---\n\nCategory: PROBABLY_PENTEST - Packages looking like typical pentest packages, but also anything that looks like testing, exploring pre-prepared kits, research \u0026 co, with clearly low-harm possibilities.\n\n\nCampaign: GENERIC-hackerone-bugbounty\n\n\nReasons (based on the campaign):\n\n\n - dependency-confusion\n\n\n - The package contains code to exfiltrate basic data from the system, like IP or username. It has a limited risk.\n",
