    "summary": "This package is a fork of the Baileys WhatsApp Web library (npm) and belongs to the \"PhantomSub\" family described by OX Security in September 2026: the publisher injected code that, without the installer asking, uses the installer's own authenticated WhatsApp session to subscribe that account to WhatsApp Channels (newsletters) the publisher chose, by sending the WhatsApp `w:mex` FOLLOW query (query_id 7871414976211147) for each target channel JID. `package/lib/Defaults/index.js` lines 78-80 ship the defaults `autoFollowNewsletterOnConnect: true`, `autoFollowNewsletterDelayMs: 90000` and `autoFollowNewsletterJid: \"120363400911374213@newsletter\"`. `package/lib/Socket/newsletter.js` lines 12-30 additionally fetch `https://raw.githubusercontent.com/iyedahruss/all-public-db/refs/heads/main/newsletter.json` at runtime and add every `@newsletter` id in it to the follow list, so the targets can change without a new npm release. `package/lib/Socket/index.js` line 11 calls `triggerAutoFollow` (`newsletter.js` line 484) on every socket; 90 seconds after the connection opens, `runAutoFollow` (line 108) sends a raw `w:mex` IQ with `query_id: QueryIds.FOLLOW` (line 139) for each target, retrying up to three times. On 2026-10-01 the remote list contained `120363418964199743@newsletter`, `120363410316899314@newsletter`, `120363429190136593@newsletter` and `120363429068662026@newsletter` (under the key `saurus`).
