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.

rimuru-md 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 src/connection.js sends the WhatsApp w:mex FOLLOW query for the channel ID(s) 120363407306241749@newsletter and the channel invite code(s) 0029Vb8dmsUElagkVPIw9X2P, 0029VbB37bgBfxoAmAlsgE0t, using the victim's authenticated session and without telling them. Same behaviour as the PhantomSub family (MAL-2026-17342).
