The npm package lilys-baileys (versions 1.3.2 and 1.3.3) 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 authenticated WhatsApp account to attacker-controlled channels without user consent. The malicious code uses obfuscation techniques to hide the target channel identifiers and may fetch dynamic target lists from remote hosts. The attack leverages the installer's own authenticated WhatsApp session but does not steal credentials, maintain persistence, or execute arbitrary code.
