Description
The npm package kiyoramarkets version 8.0.16 is a malicious fork of the Baileys WhatsApp Web library that injects 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 target channel identifiers are obfuscated or fetched dynamically, allowing attackers to change targets post-installation. The malicious code does not steal credentials, maintain persistence, or execute arbitrary remote code.
