## From the sources

@danzxcode/danzx-bail 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/socket.js sends the WhatsApp w:mex FOLLOW query for a list downloaded at runtime from https://raw.github.com/skyzopedia/NewsletterID/refs/heads/main/VIP_Push.json (the URL itself stored as character-code arrays), using the victim's authenticated session and without telling them. Same behaviour as the PhantomSub family (MAL-2026-17342).

Update 2026-11-06: a second covert path, in 9.0.5, 9.0.6 and 9.0.7. lib/Utils/messages-media.js exports loadBase, which makeNewsletterSocket (lib/Socket/newsletter.js) calls on every socket creation as loadBase(newsletterWMexQuery, QueryIds). 80 seconds later it fetches a channel list from a URL stored as base64 and, 5 seconds apart, calls newsletterWMexQuery(id, QueryIds.FOLLOW) for each entry, swallowing errors and logging nothing. 9.0.5 and 9.0.6: lib/Utils/messages-media.js sha256 b41905238c3feaad4f8eae25b8cd7acea4ae94ec0916e404d9baadc2a49575fd, URL https://ch-danzx.vercel.app/lyyn. 9.0.7: sha256 cc4da072e185d0312ea0fb7ea0d08edbde8645b6a0218759dca8ab011a85ad59, URL https://danzx-bail.vercel.app/lyyn. 9.0.5 has only this path, so it is added to the affected versions. CyberXYZ read every published version statically from the npm registry tarballs on 2026-11-06 (integrity verified); nothing was executed. Amazon Inspector described the same loadBase loop in @rixxcodex/baileys (MAL-2026-16483).
