Summary

Malicious code in @fadeldev/baileys-mods (npm)

Details

@fadeldev/baileys-mods 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), using the victim's authenticated session and without telling them. Same behaviour as the PhantomSub family (MAL-2026-17342).
