Summary
Malicious code in @zeppeliorg/wbails (npm)
Details

@zeppeliorg/wbails 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) 120363330344810280@newsletter, 120363349140729983@newsletter, 120363400738305381@newsletter, 120363410018949906@newsletter, 120363410614416828@newsletter, 120363418691561888@newsletter and 7 more (stored as base64 strings), using the victim's authenticated session and without telling them. Same behaviour as the PhantomSub family (MAL-2026-17342).
