AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The package performs an unrequested account action by following a hard-coded WhatsApp newsletter whenever a normal socket is created. The preinstall hook only checks the Node version, but that does not affect the runtime account action. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-11-05T06:53:08.784Z - **Finished:** 2026-11-05T06:54:03.810Z - **Download time:** 251 ms - **Static scan time:** 1838 ms - **AI review time:** 52936 ms - **Total time:** 55026 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 consumer creates the normal socket; the follow query runs 90 seconds after newsletter socket construction. - **Impact:** The user’s WhatsApp account follows a newsletter chosen by the package publisher. - **Evidence paths:** lib/Socket/messages-send.js, lib/Socket/newsletter.js - **Review source:** ai\_review - **Reviewed:** 2026-11-05T06:54:03.810Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The timer submits a FOLLOW query for the fixed newsletter ID through the WhatsApp connection, without an explicit follow request from the user. - **Attack narrative:** When a consumer creates the normal socket, the message socket constructs the newsletter socket. That constructor schedules a FOLLOW query 90 seconds later for the hard-coded newsletter 120363400780200098@newsletter. This uses the consumer’s WhatsApp account to follow a publisher-selected target without a user request. - **Rationale:** The package performs an unrequested account action by following a hard-coded WhatsApp newsletter whenever a normal socket is created. The preinstall hook only checks the Node version, but that does not affect the runtime account action. - **Files touched:** lib/Socket/messages-send.js, lib/Socket/newsletter.js - **Network endpoints:** WhatsApp service (S\_WHATSAPP\_NET; @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 message socket constructs the newsletter socket, which starts a timer to send a FOLLOW query for the hard-coded newsletter 120363400780200098@newsletter after 90 seconds., The newsletter query is sent to the WhatsApp service, and the package’s newsletterFollow method uses the same FOLLOW query ID., The preinstall script only checks the Node.js major version and exits for versions below 20. - **Evidence against:** The package is a WhatsApp API library, so communicating with WhatsApp is part of its stated purpose., The preinstall hook does not contact the network or collect host or project data. ## Affected versions and remediation This report applies to @denzz221/baileys@8.0.6. - Avoid installing @denzz221/baileys@8.0.6. 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.
