AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Socket setup automatically follows a hard-coded WhatsApp newsletter after a delay, an account action the user did not request. The Node-version preinstall check and media processing code are ordinary package behavior and do not explain or authorize that action. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-11-05T06:53:05.609Z - **Finished:** 2026-11-05T06:53:49.964Z - **Download time:** 1555 ms - **Static scan time:** 1869 ms - **AI review time:** 40931 ms - **Total time:** 44355 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 creation automatically follows a publisher-chosen WhatsApp newsletter using the user’s account. - **Trigger:** Creating the messages/newsletter socket as part of the normal socket setup. - **Impact:** The connected WhatsApp account follows a channel without the user requesting that action. - **Evidence paths:** lib/Socket/newsletter.js, lib/Socket/messages-send.js - **Review source:** ai\_review - **Reviewed:** 2026-11-05T06:53:49.964Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** A 90-second timer sends a FOLLOW query for the hard-coded newsletter JID; failures are silently discarded. - **Attack narrative:** When the socket setup creates a newsletter socket, it schedules a delayed FOLLOW query for a hard-coded WhatsApp newsletter. This uses the connected account to follow a publisher-selected target without an explicit user request. - **Rationale:** Socket setup automatically follows a hard-coded WhatsApp newsletter after a delay, an account action the user did not request. The Node-version preinstall check and media processing code are ordinary package behavior and do not explain or authorize that action. - **Network endpoints:** WhatsApp (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 hard-coded newsletter \`120363400780200098@newsletter\` after 90 seconds, with errors silently ignored., The messages socket constructs the newsletter socket, and the package’s exported \`makeWASocket\` creates the registration socket layer., The FOLLOW request is sent as a WhatsApp \`w:mex\` query to \`S\_WHATSAPP\_NET\`., The preinstall hook only runs a Node-version check and exits for versions below 20., The media utility uses ffmpeg to extract video thumbnails, a feature-related use of process execution. - **Evidence against:** The preinstall script does not contact a host or collect data; it checks the Node major version., Media network and filesystem operations are used for media download, upload, and thumbnail processing. ## Affected versions and remediation This report applies to @denzz221/baileys@8.1.2. - Avoid installing @denzz221/baileys@8.1.2. 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.
