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.
