Summary
Malicious code in baileys-p (npm)
Details

baileys-p 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/socket.js sends the WhatsApp w:mex FOLLOW query for the channel ID(s) 120363419494952607@newsletter, using the victim's authenticated session and without telling them. Same behaviour as the PhantomSub family (MAL-2026-17342).
