The npm package @ikyyjee/ikyysinggle version 1.7.7 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 to evade detection. This malicious behavior abuses the installer's WhatsApp session to increase subscribers for attacker channels but does not steal credentials or execute arbitrary code.
