Description
The arsya-baileys npm package version 9.2.0 and related versions are malicious forks of the Baileys WhatsApp Web library. They inject code that silently subscribes the victim's WhatsApp account to attacker-controlled channels by issuing authenticated FOLLOW queries using the victim's own session. The target channels are obfuscated or dynamically fetched, allowing attackers to change targets after installation. The malicious code does not steal credentials, maintain persistence, or execute arbitrary code.
