Description
The xzbails npm package, versions 0.0.3, 0.0.4, and 0.0.5, is part of a large family of malicious forks of the Baileys WhatsApp Web library. These forks inject code that silently subscribes the victim's WhatsApp account to attacker-controlled channels without user consent by issuing authenticated FOLLOW queries using the victim's own session. The target channels are obfuscated or dynamically fetched to evade detection. The malicious code does not steal credentials, maintain persistence, or execute arbitrary remote code.
