Description

The diezyclutch-baileys npm package, a fork of the Baileys WhatsApp library, contains malicious code that covertly exfiltrates data. The exfiltration is performed by constructing a network destination URL via obfuscated character codes that decode to an unauthorized external host (https://fiora.nixel.my.id/). This host is not part of the legitimate WhatsApp or Signal protocol traffic and is hardcoded, not configurable by users. The malicious code resides in the message-sending path, which handles session-authenticated data, enabling potential unauthorized data leakage.

Impact

This malicious code can lead to unauthorized exfiltration of sensitive session data from users of the diezyclutch-baileys package version 8.6.78. Since the exfiltration occurs in the message-sending path, it may leak authenticated session information, potentially compromising user privacy and security. There is no indication of active exploitation in the wild at this time.

Defensive guidance

Users should immediately discontinue use of diezyclutch-baileys version 8.6.78 and replace it with the official Baileys library or a trusted alternative. Verify package integrity and source before installation to avoid malicious forks. Monitor for vendor advisories or community updates regarding remediation or removal.

Summary

The diezyclutch-baileys package version 8.6.78 includes deliberately obfuscated code in lib/Socket/messages-send.js that constructs a URL from a decimal character code array. This URL points to https://fiora.nixel.my.id/, an external host unrelated to the official WhatsApp or Signal protocols. The package issues outbound requests to this host during message sending, creating a covert exfiltration channel for session-authenticated data. This behavior indicates malicious intent embedded within the package, compromising confidentiality by sending data to an unauthorized third party.
