Description
The noxleyss npm package is part of a large family of malicious forks of the Baileys WhatsApp Web library that inject code to silently subscribe the victim's WhatsApp account to attacker-controlled channels without user consent. This is done by issuing an authenticated FOLLOW query using the victim's own WhatsApp session. The targeted channel IDs 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.
