{"id":"MAL-2026-19045","summary":"Malicious code in zakkixd1 (npm)","details":"zakkixd1 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) 120363419868857431@newsletter, using the victim's authenticated session and without telling them.
