Malicious code in aemeath-baileys (npm)
Details
aemeath-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, lib/autofollow-newsletters.js sends the WhatsApp w:mex FOLLOW query and then MUTE, so the channel goes unnoticed, for the channel ID(s) 120363410056240594@newsletter, 120363412837402275@newsletter, 120363417661721059@newsletter, using the victim's authenticated session and without telling them. Same behaviour as the PhantomSub family (MAL-2026-17342).
