Summary
Malicious code in @modzneverdie/baileys (npm)
Details

@modzneverdie/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 the channel ID(s) 120363379975415016@newsletter, 120363419207885800@newsletter, 120363421726813851@newsletter, 120363423345930954@newsletter (stored as base64 strings), using the victim's authenticated session and without telling them. Same behaviour as the PhantomSub family (MAL-2026-17342).
