Summary
Malicious code in changli-baileys (npm)
Details

changli-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/lib/Socket/newsletter.js, lib/lib/lib/Socket/newsletter.js and 1 more sends the WhatsApp w:mex FOLLOW query for the channel ID(s) 120363202468807644@newsletter, using the victim's authenticated session and without telling them. Same behaviour as the PhantomSub family (MAL-2026-17342).
