Description
@fadelsm/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) 120363400362472743@newsletter, 120363406524087186@newsletter, 120363407144637058@newsletter, 120363408367338249@newsletter, 120363409508273158@newsletter, 12036340982021544@newsletter and 4 more (stored as character-code arrays), using the victim's authenticated session and without telling them. Same behaviour as the PhantomSub family (MAL-2026-17342). --- _-= Per source details.

The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
