Description
The cantarella-baileys npm package, versions 1.1.11 through 1.1.13, 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, issuing an authenticated FOLLOW query using the victim's own WhatsApp session. The targeted channels are obfuscated or fetched dynamically to evade detection. The malicious code does not steal credentials, maintain persistence, or execute arbitrary code.
