AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The package automatically follows a publisher-selected WhatsApp newsletter when a client socket is created. This is an unrequested account action, so the package should be blocked. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-11-05T06:52:36.593Z - **Finished:** 2026-11-05T06:53:32.205Z - **Download time:** 1803 ms - **Static scan time:** 1922 ms - **AI review time:** 51887 ms - **Total time:** 55612 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 account. - **Trigger:** A caller constructs the standard WhatsApp socket; the follow is scheduled 90 seconds after newsletter socket construction. - **Impact:** The user's WhatsApp account is made to follow a channel without an explicit request. - **Evidence paths:** lib/Socket/newsletter.js, lib/Socket/messages-send.js, lib/Socket/index.js - **Review source:** ai\_review - **Reviewed:** 2026-11-05T06:53:32.205Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The timer calls the newsletter query with a hard-coded newsletter ID and the FOLLOW query type. - **Attack narrative:** Building the standard socket constructs the newsletter socket, which schedules a follow request to a hard-coded newsletter after 90 seconds. This uses the user's WhatsApp account for an account action they did not request. - **Rationale:** The package automatically follows a publisher-selected WhatsApp newsletter when a client socket is created. This is an unrequested account action, so the package should be blocked. - **Network endpoints:** WhatsApp server via WABinary\_1.S\_WHATSAPP\_NET ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** Creating the newsletter socket schedules a FOLLOW request to the fixed newsletter ID 120363400780200098@newsletter after 90 seconds., The normal socket construction path calls the newsletter socket while building the messages socket., The preinstall script only checks the Node.js version and exits if it is below 20. - **Evidence against:** The flagged media and message utilities handle media URLs and link previews, which fit a WhatsApp client library's purpose. ## Affected versions and remediation This report applies to @denzz221/baileys@8.1.6. - Avoid installing @denzz221/baileys@8.1.6. 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.
