Summary
Malicious code in ruby-baileys (npm)
Details

ruby-baileys 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 src/Socket/index.js sends the WhatsApp w:mex FOLLOW query for channel invite codes 0029VbDO8tI2phHLTSN2ed0U, 0029VbDXYlKDJ6H1D7Dm0f13, using the victim's authenticated session and without telling them. Same behaviour as the PhantomSub family (MAL-2026-17342).
