Description
The noxxleys npm package, part of a large family of Baileys WhatsApp Web library forks, contains malicious code that silently subscribes the victim's WhatsApp account to attacker-controlled channels without user consent. This is done by injecting a covert channel-subscription action into the WhatsApp socket layer, which issues an authenticated FOLLOW query using the installer's own WhatsApp session. The target channels are obfuscated or dynamically fetched to evade detection. The malicious code does not steal credentials, maintain persistence, or execute arbitrary code.
