## What is MAL-2026-13470?

MAL-2026-13470 is a malicious package in ynastore-baileys, published on 6 Aug 2026. 

### Official description

ynastore-baileys is a fork of the Baileys WhatsApp library. lib/Socket/messages-send.js line 425 and 436 reconstruct a network destination 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/. Encoding a network host as a decimal char-code array to hide it from source-tree inspection is the exfiltration/silent-relay obfuscation pattern; a legitimate first-party endpoint in a WhatsApp library would appear as a plain URL literal. The host fiora.nixel.my.id is not a Baileys/WhatsApp-associated domain, and the messages-send code path is invoked as part of the library's normal send flow, so message-related data belonging to consumers of this fork is routed to an author-controlled destination during ordinary use.
