{"id":"MAL-2026-18862","summary":"Malicious code in @lubyzzxmods/baileys (npm)","details":"@lubyzzxmods/baileys 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 a list downloaded at runtime from https://raw.githubusercontent.com/lubyzofficial/channel/refs/heads/main/idch.json, using the victim's authenticated session and without telling them.
