AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The package silently follows a hard-coded WhatsApp newsletter through the user’s authenticated account during ordinary socket setup. This is an unrequested account action and warrants blocking. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-11-05T06:53:05.855Z - **Finished:** 2026-11-05T06:54:01.016Z - **Download time:** 1289 ms - **Static scan time:** 1884 ms - **AI review time:** 51987 ms - **Total time:** 55161 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:** The package automatically follows a publisher-chosen WhatsApp newsletter when its newsletter socket is constructed. - **Trigger:** Normal message socket construction; the follow is scheduled for 90 seconds later. - **Impact:** The user’s WhatsApp account is made to follow a channel without a request to do so. - **Evidence paths:** lib/Socket/newsletter.js, lib/Socket/messages-send.js - **Review source:** ai\_review - **Reviewed:** 2026-11-05T06:54:01.016Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** A timer calls newsletterWMexQuery with a fixed newsletter ID and the FOLLOW query ID through the authenticated WhatsApp connection. - **Attack narrative:** When the normal message socket is constructed, the package constructs its newsletter socket too. That socket schedules a FOLLOW request 90 seconds later for newsletter 120363400780200098@newsletter. The request uses the account’s authenticated WhatsApp connection and has no user-request check, causing an account action toward a target chosen by the publisher. - **Rationale:** The package silently follows a hard-coded WhatsApp newsletter through the user’s authenticated account during ordinary socket setup. This is an unrequested account action and warrants blocking. - **Files touched:** lib/Socket/newsletter.js, lib/Socket/messages-send.js - **Network endpoints:** WhatsApp service via the authenticated socket ### 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 action for the hard-coded newsletter 120363400780200098@newsletter after 90 seconds., The message socket factory creates the newsletter socket as part of its normal construction path, so the follow is not gated on a user request., The action is sent through the package’s WhatsApp query mechanism using the user’s authenticated socket. - **Evidence against:** The preinstall script runs engine-requirements.js, which checks the Node.js major version and exits on versions below 20., The flagged fixed newsletter ID in dugong.js appears in forwarded-message attribution within handleEvent, which relays an event to the caller-supplied JID. ## Affected versions and remediation This report applies to @denzz221/baileys@8.1.7. - Avoid installing @denzz221/baileys@8.1.7. 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.
