During installation or import, the package exfiltrates basic information in a dependency confusion attempt. 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.
