{"id":"MAL-2026-18828","summary":"Malicious code in @fadeldev/baileys-mod (npm)","details":"@fadeldev/baileys-mod is a fork of the Baileys WhatsApp Web library that silently subscribes the installer's own WhatsApp account to WhatsApp Channels chosen by the publisher. When the socket connects, code in lib/Socket/newsletter.js sends the WhatsApp w:mex FOLLOW query for the channel ID(s) 120363408367338249@newsletter, 120363409508273158@newsletter, 12036340982021544@newsletter (stored as character-code arrays) and a list downloaded at runtime from https://raw.githubusercontent.com/D4mxor/Screaper/refs/heads/main/idChannel.json, using the victim's authenticated session and without telling them.
