The noverojs npm package versions 1.0.1 and 1.0.4 contain malicious code that silently subscribes a victim's WhatsApp account to attacker-controlled channels without user consent. This is achieved by injecting a covert subscription action into the WhatsApp socket layer, which issues an authenticated FOLLOW query using the installer's own WhatsApp session. The target channels are obfuscated or dynamically fetched, allowing attackers to change targets post-installation. The malicious code does not exfiltrate credentials, establish persistence, or execute arbitrary remote code.
