Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The socket constructor triggers authenticated WhatsApp follow actions toward hard-coded targets without user consent. This is malicious account manipulation, even though the install hook only checks the Node.js version. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-30T19:02:04.179Z - **Finished:** 2026-10-30T19:02:55.075Z - **Download time:** 517 ms - **Static scan time:** 1700 ms - **AI review time:** 48677 ms - **Total time:** 50896 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:** Socket construction automatically uses the authenticated WhatsApp account to follow publisher-selected newsletters. - **Trigger:** Calling the package's socket constructor. - **Impact:** The user's account is made to follow newsletters selected by the package publisher. - **Evidence paths:** lib/Socket/index.js, lib/Socket/business.js, lib/Socket/messages-recv.js, lib/Socket/messages-send.js, lib/Socket/username.js, lib/Socket/newsletter.js, lib/Socket/mex.js - **Review source:** ai\_review - **Reviewed:** 2026-10-30T19:02:55.075Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The newsletter socket schedules four WhatsApp newsletter follow mutations to hard-coded IDs without a caller request or consent check. - **Attack narrative:** When a caller constructs the socket, the package builds the newsletter layer, which schedules four follow mutations to hard-coded newsletter IDs within 10 to 25 seconds. The requests use the user's authenticated WhatsApp socket, changing account state toward targets chosen by the publisher without a request to follow them. - **Rationale:** The socket constructor triggers authenticated WhatsApp follow actions toward hard-coded targets without user consent. This is malicious account manipulation, even though the install hook only checks the Node.js version. - **Network endpoints:** web.whatsapp.com ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The public socket builder constructs the business, receive, and message socket layers, which create the username and newsletter sockets., Newsletter socket construction schedules four follow requests to hard-coded newsletter IDs after delays of 10 to 25 seconds, without requiring a follow request from the caller., The follow mutations are sent through the WhatsApp socket query path. - **Evidence against:** The preinstall script only checks the Node.js major version and exits for versions below 20. ## Affected versions and remediation This report applies to @sakataa/baileys@2.0.0. - Avoid installing @sakataa/baileys@2.0.0. 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.
