The npm package @bellaxchuu/privatebails version 1.4.1 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 target channels are obfuscated or dynamically fetched to evade detection. This behavior abuses the victim's own WhatsApp session to increase subscribers for attacker channels but does not steal credentials, maintain persistence, or execute arbitrary code.
