At runtime, newsletter socket code contacts a base64-obscured third-party endpoint and performs hidden WhatsApp queries for returned IDs. - **Trigger:** npm installation; creating a newsletter socket after a 90-second delay - **Impact:** Hijacks imports of @whiskeysockets/baileys and causes unrequested network/account activity. - **Evidence paths:** package.json, scripts/postinstall.js, lib/Socket/newsletter.js, lib/index.js, lib/Utils/messages-media.js - **Review source:** ai\_review - **Reviewed:** 2026-07-22T20:04:46.996Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Dependency substitution plus concealed remote-driven WhatsApp queries - **Attack narrative:** The postinstall script runs without user action, removes consumer node\_modules/@whiskeysockets/baileys, and writes a replacement manifest redirecting that package name to this package. Separately, newsletter initialization decodes and fetches a third-party JID list, then silently sends WhatsApp MEX queries for every returned identifier after a delay. These are not necessary for ordinary import/export compatibility or user-invoked messaging. - **Rationale:** Concrete install-time dependency replacement and concealed runtime network activity establish malicious behavior. The ordinary media helpers do not mitigate those independent attack paths. - **Files touched:** package.json, scripts/postinstall.js, node\_modules/@whiskeysockets/baileys, node\_modules/@whiskeysockets/baileys/package.json, lib/Socket/newsletter.js - **Network endpoints:** https://files.gifted.co.ke/file/chJids.json, s.whatsapp.net ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs postinstall, scripts/postinstall.js deletes and replaces consumer @whiskeysockets/baileys, lib/Socket/newsletter.js fetches hidden files.gifted.co.ke list and queries each JID - **Evidence against:** lib/index.js is a conventional export wrapper, messages-media network and ffmpeg paths are media features ## Public findings ### 1.
