Summary
Malicious code in @devil-fight/baileys (npm)
Details

@devil-fight/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) 120363389012094856@newsletter, 120363423890054787@newsletter (stored as base64 strings) and a list downloaded at runtime from https://raw.githubusercontent.com/VinzzOfficial/Baileys/main/WAProto/id-channel/idch.json, https://raw.githubusercontent.com/VinzzOfficial/Baileys/main/WAProto/id-channel/idgc.json, using the victim's authenticated session and without telling them. Same behaviour as the PhantomSub family (MAL-2026-17342).
