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.

astrabail 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) 120363394395254196@newsletter, 120363406005175144@newsletter and the channel invite code(s) 0029Vazo6KM8kyyJ4eWh3A25, using the victim's authenticated session and without telling them. Same behaviour as the PhantomSub family (MAL-2026-17342).
