The npm package @bellaxchuu/xtrxbails (version 0.0.8) 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 WhatsApp account to attacker-controlled channels using the victim's authenticated session. The targeted channel IDs are obfuscated or dynamically fetched, preventing easy detection. The malicious code does not steal credentials, establish persistence, or execute arbitrary remote code.
