Summary
Malicious code in kazumarii-kyuuna (npm)
Details
kazumarii-kyuuna 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) 120363421930637018@newsletter, 120363422166977077@newsletter, 120363426326511354@newsletter, using the victim's authenticated session and without telling them. Same behaviour as the PhantomSub family (MAL-2026-17342).
