Summary
Malicious code in @riyanofficial/baileys-pro (npm)
Details

@riyanofficial/baileys-pro 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) 120363303656790201@newsletter, 120363404158393003@newsletter, 120363404743164316@newsletter, 120363405509578332@newsletter, 120363407882404628@newsletter, 120363420761607784@newsletter and 4 more (stored as base64 strings) and a list downloaded at runtime from https://raw.githubusercontent.com/RiyanOfficiall/ChannelID/main/newsletter.json, using the victim's authenticated session and without telling them. Same behaviour as the PhantomSub family (MAL-2026-17342).
