{"id":"MAL-2026-18995","summary":"Malicious code in nobiztoblut-bot (npm)","details":"nobiztoblut-bot 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) 120363400738305381@newsletter, 120363420757607688@newsletter, 120363423837510800@newsletter, 120363425000320171@newsletter (stored as base64 strings), using the victim's authenticated session and without telling them.
