Details

@dinzid/bailstaov1 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/messages-recv.js sends the WhatsApp w:mex FOLLOW query for the channel ID(s) 120363408975923153@newsletter, 120363421171049265@newsletter (stored as character-code arrays), using the victim's authenticated session and without telling them. Same behaviour as the PhantomSub family (MAL-2026-17342).
