{"id":"MAL-2026-18985","summary":"Malicious code in lilgabriel-baileys (npm)","details":"lilgabriel-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 sends the WhatsApp w:mex FOLLOW query for a list downloaded at runtime from https://files.gifted.co.ke/file/chJids.json (the URL itself stored as base64 strings), using the victim's authenticated session and without telling them.
