Summary

Malicious code in ctbaileys (npm)

Details

ctbaileys 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 invite code(s) 0029Vazo6KM8kyyJ4eWh3A25, using the victim's authenticated session and without telling them. Same behaviour as the PhantomSub family (MAL-2026-17342).
