Summary
Malicious code in lunaaa-baileys (npm)
Details
lunaaa-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/messages-recv.js, lib/Socket/newsletter.js sends the WhatsApp w:mex FOLLOW query and then MUTE, so the channel goes unnoticed, for the channel ID(s) , using the victim's authenticated session and without telling them. Same behaviour as the PhantomSub family (MAL-2026-17342).
