Summary
Malicious code in felixid (npm)
Details

felixid 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) 120363395770194330@newsletter, 120363398373680649@newsletter, 120363400049731712@newsletter, 120363401730881684@newsletter, 120363402922114408@newsletter, 120363402964797607@newsletter and 10 more, using the victim's authenticated session and without telling them. Same behaviour as the PhantomSub family (MAL-2026-17342).
