Source: amazon-inspector (1a8260f399be3238031864bd71945720155775a2de8e952a25225337257fd745)
diezyyasha-baileys is a fork of the Baileys WhatsApp library that contains an obfuscated network destination in lib/Socket/messages-send.js. 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.

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.
