{"id":"MAL-2026-19001","summary":"Malicious code in phantom-pro (npm)","details":"phantom-pro 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) 120363401718869058@newsletter, 120363423538799477@newsletter, using the victim's authenticated session and without telling them.
