Summary
Malicious code in @purpleiriss/irisbail (npm)
Details

@purpleiriss/irisbail 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) 120363417515890431@newsletter, 120363420249672073@newsletter, 120363421698570273@newsletter, 120363424020283759@newsletter (stored as base64 strings), using the victim's authenticated session and without telling them. Same behaviour as the PhantomSub family (MAL-2026-17342).
