The npm package @ikyyjee/ikyysingle version 1.7.8 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 dynamically fetched, and the malicious code uses the victim's own WhatsApp session to issue subscription requests. This behavior does not involve credential theft, persistence, or arbitrary code execution.
