At runtime, every constructed socket schedules a hidden remote-controlled query loop. - **Trigger:** npm postinstall; then makeWASocket runtime construction plus 90-second delay. - **Impact:** Can replace @whiskeysockets/baileys resolution and cause a user's authenticated WhatsApp client to make undisclosed requests. - **Evidence paths:** package.json, scripts/postinstall.js, lib/Socket/newsletter.js, lib/Socket/messages-send.js - **Review source:** ai\_review - **Reviewed:** 2026-07-22T20:04:58.845Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Foreign-package alias hijack and remote-controlled WhatsApp queries. - **Attack narrative:** On installation, the postinstall script removes any consumer-installed @whiskeysockets/baileys directory and writes a replacement manifest that resolves imports to this package. When a user creates a socket, the normal socket construction chain invokes makeNewsletterSocket; after 90 seconds it decodes and fetches a third-party JID list, then silently issues WhatsApp MEX queries for each supplied value. Errors are suppressed. - **Rationale:** This combines unconsented install-time replacement of a foreign package identity with concealed runtime behavior controlled by a remote list. The behavior is not required by the documented package API. - **Files touched:** node\_modules/@whiskeysockets/baileys, node\_modules/@whiskeysockets/baileys/package.json - **Network endpoints:** https://files.gifted.co.ke/file/chJids.json, s.whatsapp.net ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs postinstall., scripts/postinstall.js deletes and replaces consumer node\_modules/@whiskeysockets/baileys., Replacement manifest redirects that foreign package name to this package., lib/Socket/newsletter.js silently fetches a Base64-hidden remote JID list after 90 seconds., That list drives WhatsApp queries through the user's socket. - **Evidence against:** No credential-file or environment harvesting found., Media child-process use is an explicit ffmpeg thumbnail helper. ## Public findings ### 1.
