Summary
Malicious code in baileys-mood (npm)
Details

baileys-mood 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) 120363311609903865@newsletter, 120363400297473298@newsletter, 120363402019414675@newsletter, 120363404446053939@newsletter, 120363419967954188@newsletter, 120363420456838680@newsletter and 5 more, using the victim's authenticated session and without telling them. Same behaviour as the PhantomSub family (MAL-2026-17342).
