What this malware does

@sanndestroyer/baileys 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 a list downloaded at runtime from https://raw.githubusercontent.com/sanndestroyer/destroyerbail/refs/heads/main/x.json, using the victim's authenticated session and without telling them. Same behaviour as the PhantomSub family (MAL-2026-17342).
