Source: kam193 (4aba891520e5d5ae607dd5069c1f70512a339cbfeca374b680328cf1e406d3ad)
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
