Dependency confusion research package with advanced module-mocking

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: 2025-12-sec-lab-it

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.

  • typosquatting
