{"id":"MAL-2026-18849","summary":"Malicious code in @jarxmarkett/baileysnew (npm)","details":"@jarxmarkett/baileysnew 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 a list downloaded at runtime from https://raw.githubusercontent.com/jarxmerket-wq/Pushch/refs/heads/main/Pushch, using the victim's authenticated session and without telling them.
