lib/Socket/messages-send.js contains network destinations reconstructed via String.fromCharCode(...) arrays that decode to https://fiora.nixel.my.id/. The host is assembled from decimal char codes rather than appearing as a plain string literal, which is a deliberate obfuscation pattern used to hide exfiltration or covert-callback endpoints from casual review. The file is part of the WhatsApp/Baileys socket message-send path, where such hidden destinations are consistent with covert use of the caller's session (exfiltrating message/session data or performing actions with the installer's authenticated identity) rather than any documented library behavior. The package is a fork of a legitimate messaging library and no documented purpose justifies a char-code-hidden third-party host inside the message-send pipeline.
