MAL-2026-13482 Malicious code in diezyclutch-baileys (npm)

diezyclutch-baileys is a fork of the Baileys WhatsApp library. In lib/Socket/messages-send.js the code constructs a network destination from a String.fromCharCode(…) array that decodes to https://fiora.nixel.my.id/ and issues outbound requests to that host from the message-sending path. Reconstructing the destination URL from a decimal char-code array is deliberate obfuscation of the exfil endpoint; the host is not part of Baileys' documented WhatsApp/Signal protocol traffic and is not a caller-configurable option. This is the canonical shape of a covertly injected exfiltration channel in a WhatsApp-session library, whose messages-send path handles session-authenticated data.

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.
