What this malware does

@dinzid/bailstao 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) 120363186130999681@newsletter, 120363303656790201@newsletter, 120363315657907625@newsletter, 120363388739599619@newsletter, 120363403108262988@newsletter, 120363404743164316@newsletter and 14 more (some stored as base64 strings), using the victim's authenticated session and without telling them. Same behaviour as the PhantomSub family (MAL-2026-17342).
