Description
The npm package monte-md-baileys version 1.0.0 is a malicious fork of the Baileys WhatsApp Web library that silently subscribes the victim's WhatsApp account to attacker-controlled channels without user consent. It achieves this by injecting code that issues an authenticated FOLLOW query using the victim's own WhatsApp session. The targeted channel identifiers are obfuscated or dynamically fetched to evade detection. This behavior does not involve credential theft, persistence, or remote code execution.
