If this package is installed

Remove it, treat the machine (or CI runner) as compromised, and rotate every secret, token and key it could access — from a different, clean machine.

Details

mid-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 the channel ID(s) 120363301416835342@newsletter, 120363426558938675@newsletter and the channel invite code(s) 0029VbCinBtD38CRx4Oh4n1U and a list downloaded at runtime from https://raw.githubusercontent.com/gcamerator/My/refs/heads/main/ids.json, using the victim's authenticated session and without telling them. Same behaviour as the PhantomSub family (MAL-2026-17342).
