The npm package @xsat10/baileys-xsat version 2.0.0 is a fork of the Baileys WhatsApp Web library that contains malicious code. Although some code patterns resemble normal media upload and connectivity checks, the fork's provenance is suspicious due to prior instances of Baileys forks embedding covert side effects using authenticated WhatsApp sessions. The package is considered fully compromising to any computer on which it is installed, potentially allowing an attacker full control. Immediate removal and secret rotation are advised.
