Description
The levvleys 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 using the victim's authenticated session. This covert subscription occurs via an injected FOLLOW query after connecting to WhatsApp, with target channels obfuscated or dynamically fetched. The malicious code does not exfiltrate credentials, establish persistence, or execute arbitrary remote code.
