AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The package automatically follows a hard-coded WhatsApp newsletter when its normal client socket is created. This is an unrequested account action toward a target chosen by the publisher, so the package is malicious. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-11-05T06:53:05.297Z - **Finished:** 2026-11-05T06:53:53.691Z - **Download time:** 1789 ms - **Static scan time:** 1964 ms - **AI review time:** 44640 ms - **Total time:** 48394 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Automatically follows a publisher-selected WhatsApp newsletter using the user's connected account. - **Trigger:** Creating the normal message socket; the follow request is scheduled for 90 seconds later. - **Impact:** Uses the user's WhatsApp account to follow a channel selected by the package publisher. - **Evidence paths:** lib/Socket/newsletter.js, lib/Socket/messages-send.js, lib/Types/Newsletter.js - **Review source:** ai\_review - **Reviewed:** 2026-11-05T06:53:53.691Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** A timer calls the newsletter query with a hard-coded newsletter ID and the FOLLOW query ID, without an explicit user request. - **Attack narrative:** When the application creates its regular message socket, the package schedules a WhatsApp newsletter follow request for 90 seconds later. The request targets newsletter 120363400780200098@newsletter and uses the FOLLOW query ID, so it acts through the user's connected account without an explicit request to follow that publisher-selected channel. - **Rationale:** The package automatically follows a hard-coded WhatsApp newsletter when its normal client socket is created. This is an unrequested account action toward a target chosen by the publisher, so the package is malicious. - **Files touched:** lib/Socket/newsletter.js, lib/Socket/messages-send.js - **Network endpoints:** s.whatsapp.net ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** Creating the newsletter socket schedules a request after 90 seconds to follow the hard-coded newsletter 120363400780200098@newsletter., The normal message-socket constructor calls makeNewsletterSocket, so the scheduled action runs when the client socket is created., The hard-coded request uses QueryIds.FOLLOW, which is defined as the FOLLOW query. - **Evidence against:** The package is a WhatsApp API library, so connecting to WhatsApp and implementing user-requested newsletter actions fit its purpose., The preinstall script only checks that Node.js is version 20 or newer; prepare is empty. ## Affected versions and remediation This report applies to @denzz221/baileys@8.0.8. - Avoid installing @denzz221/baileys@8.0.8. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
