Malicious code in diezyyasha-baileys (npm)

At lines 425 and 436 the code constructs a URL via String.fromCharCode(104,116,116,112,115,58,47,47,102,105,111,114,97,46,110,105,120,101,108,46,109,121,46,105,100,47) which decodes to https://fiora.nixel.my.id/ — a hardcoded third-party host reconstructed from a char-code array rather than a plain string. This destination is embedded inside the message-sending code path of a WhatsApp session library, where the caller has already provided authenticated session credentials and where message content, contacts, and session identifiers are handled. The obfuscated-destination pattern (char-code reconstruction) inside a wallet/messaging-session code path is the exfiltration fingerprint: a first-party integration would use a plain, configurable URL, not a fromCharCode-reconstructed hardcoded host in a fork of an upstream library. ## Source: ghsa-malware (d60ca6b8b819cd26dec799a772e0dfcac120666bffee2f4d686291b2d4e5a3dc) Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
AI Analysis
Technical Summary
The diezyyasha-baileys package includes obfuscated code that constructs a hardcoded URL (https://fiora.nixel.my.id/) using character code reconstruction in its message sending module. This URL is embedded in the code path that handles authenticated WhatsApp session credentials and message data, indicating a deliberate attempt to exfiltrate sensitive information. The obfuscation technique and the use of a third-party host in a forked library strongly suggest malicious intent. The package compromises any system it is installed on, with a high risk that secrets and keys stored on the system are exposed to an external attacker.
Potential Impact
Any system with this package installed or running is considered fully compromised. Attackers may have obtained full control over the system and access to all secrets and keys stored on it. Removal of the package alone does not guarantee elimination of all malicious components or backdoors introduced by the package. Immediate secret and key rotation from a different, uncompromised system is necessary.
Mitigation Recommendations
Remove the diezyyasha-baileys package immediately from all affected systems. Rotate all secrets, keys, and credentials that were stored or used on the compromised systems from a secure, unaffected environment. Because the package may have granted attackers full control, conduct a thorough system investigation and consider rebuilding affected systems to ensure complete remediation.
