Source: kam193 (afe91149c788d349c6c0d31487fb417ce5fabc059b447dc4289b1e74f2cd161c)

Research packages targeting typosquatting and dependency confusions, without really harmful behaviour - just calling home through DNS resolver.

Related to 2025-06-stubsout (using the same remote domain), but without dangerous activity

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: 2025-06-diar-ai-basic

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.

  • typosquatting
