Summary
Malicious code in @raffnotdev/baileys (npm)
Details

@raffnotdev/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) 120363419110835885@newsletter, 120363424295522327@newsletter, 120363426470081124@newsletter, 120363429563611349@newsletter (stored base64-encoded), using the victim's authenticated session and without telling them. Same behaviour as the PhantomSub family (MAL-2026-17342).
