Source: kam193 (ab2d45d38003a542b3db3afaf891f8269c46e7ac1c342c06148f8859a03bc00e)

Importing the module exfiltrates basic information using DNS queries. There is no other purpose of the package.


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: 2025-01-just-framework

Reasons (based on the campaign):

  • The package contains code to exfiltrate basic data from the system, like IP or username. It has a limited risk.

  • dependency-confusion
