Malicious code in @bellaxchuu/familyxtrx (npm)
The npm package @bellaxchuu/familyxtrx version 0.1.5 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, allowing attackers to change targets post-installation. The malicious code abuses the installer's authenticated session but does not steal credentials, maintain persistence, or execute arbitrary remote code.
AI Analysis
Technical Summary
The @bellaxchuu/familyxtrx package (version 0.1.5) is one of over 100 near-identical malicious forks of the Baileys WhatsApp Web library. These forks modify the WhatsApp socket connection to issue an authenticated 'w:mex' FOLLOW query to attacker-chosen WhatsApp Channel/Newsletter JIDs, subscribing the victim's account to these channels silently. The target JIDs are hidden using obfuscation techniques such as base64 encoding, XOR, or runtime reconstruction, or fetched dynamically from attacker-controlled remote sources. This mechanism leverages the installer's own authenticated WhatsApp session to increase subscribers for attacker channels but does not exfiltrate credentials, establish persistence, or allow remote code execution.
Potential Impact
Victims unknowingly subscribe their WhatsApp accounts to attacker-controlled channels, potentially exposing them to unwanted content or spam. There is no credential theft, persistence, or remote code execution involved. The main impact is unauthorized subscription leveraging the victim's authenticated session.
Mitigation Recommendations
No official patch or remediation is provided. Users should avoid installing or using the affected package version 0.1.5. Since the malicious action depends on the installer's authenticated WhatsApp session, removing or replacing the package with a trusted alternative is recommended. Monitor for suspicious channel subscriptions in WhatsApp and revoke unauthorized channel memberships if possible.
