malvin-wa 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) 120363397787532298@newsletter, 120363401425960788@newsletter, 120363401712599053@newsletter, 120363402984117316@newsletter, 120363403088190386@newsletter, 120363403341539432@newsletter and 1 more, using the victim's authenticated session and without telling them. Same behaviour as the PhantomSub family (MAL-2026-17342).
