The saturn-baileys npm package (version 1.0.0) is a malicious fork of the Baileys WhatsApp Web library that injects covert subscription actions into the WhatsApp socket layer. Upon connection, it silently subscribes the victim's WhatsApp account to attacker-controlled channels without user consent by issuing authenticated FOLLOW queries. The target channels are obfuscated or dynamically fetched, allowing attackers to change targets post-installation. The malicious code abuses the installer's authenticated session but does not steal credentials, maintain persistence, or execute arbitrary code.
