The npm package @lendkzn/xntaabail version 7.0.0 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 fetched dynamically, and the malicious action uses the installer's own WhatsApp session to perform the subscription. This behavior does not involve credential theft, persistence, or arbitrary code execution.
