This changes the connected account’s subscriptions without a caller-selected target. - **Trigger:** A consumer creates a socket and its WhatsApp connection opens. - **Impact:** The connected account is subscribed to a newsletter without an explicit caller request. - **Evidence paths:** package.json, lib/index.js, lib/Socket/index.js, lib/Defaults/index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-18T22:19:01.321Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** A connection event handler calls the newsletter-follow operation with a hard-coded newsletter identifier. - **Attack narrative:** The package’s main entrypoint exports a socket factory whose connection-open handler follows a hard-coded newsletter. The action runs automatically against the connected account and has no caller-selected target or consent guard. - **Rationale:** Source inspection confirms an automatic, publisher-selected account action on connection open. This is concrete behavior that can alter a consumer’s WhatsApp subscriptions without an explicit request. - **Files touched:** package.json, lib/index.js, lib/Socket/index.js, lib/Defaults/index.js - **Network endpoints:** wss://web.whatsapp.com/ws/chat ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package entrypoint exports the socket factory that contains the automatic follow callback., On connection open, the callback follows a fixed newsletter JID without caller-selected input., The follow uses the connected account and runs once per socket., The default connection targets WhatsApp’s WebSocket service. ## Affected versions and remediation This report applies to @hanzofc/baileys@7.2.1. - Avoid installing @hanzofc/baileys@7.2.1.
