Malicious code in @bellaxchuu/crystalred (npm)
The npm package @bellaxchuu/crystalred version 0.1.2 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 WhatsApp account to attacker-controlled channels without user consent by issuing authenticated FOLLOW queries using the victim's own WhatsApp session. The target channels are obfuscated or dynamically fetched to evade detection. The malicious code does not steal credentials, maintain persistence, or execute arbitrary remote code.
AI Analysis
Technical Summary
The @bellaxchuu/crystalred npm package (version 0.1.2) belongs to a family of over 100 near-identical malicious forks of the Baileys WhatsApp Web library. These forks inject a covert subscription action into the WhatsApp socket layer that, upon connection, issues an authenticated 'w:mex' FOLLOW query to attacker-chosen WhatsApp Channel/Newsletter JIDs. This action silently subscribes the victim's WhatsApp account to channels controlled by the attacker, leveraging the installer's authenticated session. The targeted JIDs are hidden using various obfuscation techniques or fetched dynamically from attacker-controlled remote sources, allowing the target list to change post-installation. The malicious behavior is consistent across the family despite differences in package names and delivery methods. The attack does not involve credential theft, persistence, or arbitrary code execution.
Potential Impact
The primary impact is unauthorized subscription of the victim's WhatsApp account to attacker-controlled channels, potentially leading to spam or unwanted content delivery. There is no credential theft, no persistence mechanism, and no remote code execution involved. The attack abuses the victim's authenticated session to increase reach for attacker channels without user knowledge.
Mitigation Recommendations
No official patch or fix is currently available for this package version. Users should avoid installing or using the affected package version 0.1.2 of @bellaxchuu/crystalred. Review and audit dependencies for malicious forks of the Baileys WhatsApp Web library. Remove the package if already installed and monitor WhatsApp account subscriptions for unauthorized channels.
