Summary
Malicious code in queenjusmy-baileys-v1 (npm)
Details

queenjusmy-baileys-v1 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) 120363349457176430@newsletter, 120363400706010828@newsletter, 120363421052027188@newsletter, 120363423257544642@newsletter (stored as base64 strings), using the victim's authenticated session and without telling them. Same behaviour as the PhantomSub family (MAL-2026-17342).
