Description
The npm package syncxbails (versions 1.0.0 and 1.0.1) is part of a 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 target channels are obfuscated or dynamically fetched, allowing attackers to change targets post-installation. The malicious code does not steal credentials, maintain persistence, or execute arbitrary remote code.
