Source: kam193 (1d66c45b27d4ff7595d8a13a91515450c248dc50a6531199f0254bbd9d6440bb)
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.
