Malicious code in @bellaxchuu/velvetry (npm)
The npm package @bellaxchuu/velvetry versions 0.1.3 and 0.1.4 contains malicious code that silently subscribes the victim's WhatsApp account to attacker-controlled channels without user consent. This is done by injecting a covert subscription action into the WhatsApp socket layer, leveraging the installer's authenticated WhatsApp session. The targeted channel IDs are obfuscated or dynamically fetched, allowing attackers to change targets post-installation. The malicious code does not steal credentials, maintain persistence, or execute arbitrary code.
AI Analysis
Technical Summary
The @bellaxchuu/velvetry npm package (versions 0.1.3 and 0.1.4) is part of a large family of malicious forks of the Baileys WhatsApp Web library. These forks inject code that, upon connecting to WhatsApp, issues an authenticated FOLLOW query using the victim's own WhatsApp session to subscribe them to attacker-chosen WhatsApp channels. The targeted channel IDs are hidden using obfuscation techniques or fetched dynamically from attacker-controlled remote sources. This behavior abuses the victim's authenticated session to increase subscribers for attacker channels without exfiltrating credentials or executing arbitrary code.
Potential Impact
Victims unknowingly subscribe their WhatsApp accounts to attacker-controlled channels, potentially exposing them to unwanted content or spam. The attack leverages the victim's authenticated session but does not compromise credentials or enable remote code execution. There is no persistence or direct data exfiltration involved.
Mitigation Recommendations
No official patch or remediation is currently documented. Users should avoid installing or using the affected versions (0.1.3 and 0.1.4) of the @bellaxchuu/velvetry package. Review and verify the integrity of npm packages before installation, especially those related to WhatsApp Web libraries. Monitor for updates or advisories from the package maintainers or npm registry regarding fixes or removals.
