Malicious code in @sairidev/baileys-new (npm)
The npm package @sairidev/baileys-new version 0.3.21 contains malicious code that silently subscribes the victim's WhatsApp account to attacker-controlled channels without user consent. This is achieved by injecting a covert subscription action into the WhatsApp socket connection, leveraging the installer's authenticated WhatsApp session. The targeted channel identifiers are obfuscated or dynamically fetched, allowing attackers to modify targets post-installation. The malicious code does not steal credentials, maintain persistence, or execute arbitrary remote code.
AI Analysis
Technical Summary
The @sairidev/baileys-new npm package (version 0.3.21) is part of a large family of Baileys WhatsApp Web library forks that inject a covert subscription action into the WhatsApp socket layer. Upon connection, the injected code issues an authenticated 'w:mex' FOLLOW query using the installer's own WhatsApp session to subscribe the victim's account to attacker-chosen WhatsApp Channel/Newsletter JIDs. The target JIDs are obfuscated or dynamically retrieved from attacker-controlled sources, enabling stealthy and flexible targeting. The malicious behavior is limited to channel subscription abuse and does not include credential exfiltration, persistence, or arbitrary code execution.
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 allow remote code execution. There is no indication of persistence or broader system compromise.
Mitigation Recommendations
No official patch or remediation is currently documented for this malicious package version. Users should avoid installing or using @sairidev/baileys-new version 0.3.21 and related forks identified as malicious. Review and verify the integrity of Baileys library packages before installation. Since this is a malicious package distributed via npm, removing the package and revoking any unauthorized WhatsApp channel subscriptions manually is recommended. Monitor official advisories for updates or fixes.
