## From the sources

reyz4you-baileys-v1 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 index.js sends the WhatsApp w:mex FOLLOW query for the channel ID(s) 120363405947742419@newsletter, 120363421096003443@newsletter, using the victim's authenticated session and without telling them. Same behaviour as the PhantomSub family (MAL-2026-17342).
