The npm package @bellaxchuu/skyblue version 2.1.2 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 targeted channel identifiers are obfuscated or dynamically fetched at runtime to evade detection. The malicious code abuses the installer's own WhatsApp session to increase subscribers for attacker channels but does not steal credentials, maintain persistence, or execute arbitrary code.
