The npm package @bellaxchuu/flowblue version 1.5.7 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, enabling attackers to change targets post-installation. The malicious code abuses the installer's WhatsApp session to increase subscribers for attacker channels but does not steal credentials, maintain persistence, or execute arbitrary remote code.
