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 channel when its normal socket is created, using the user's account for an action they did not request. The preinstall hook is only a Node.js version check, but it does not mitigate the automatic runtime account action. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-11-05T07:10:06.583Z - **Finished:** 2026-11-05T07:11:31.070Z - **Download time:** 1552 ms - **Static scan time:** 1795 ms - **AI review time:** 81140 ms - **Total time:** 84487 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 channel using the user's connected account. - **Trigger:** Creating the normal socket through the package's runtime API; the action is scheduled for 10 seconds later. - **Impact:** The user's account follows a channel they did not choose or request. - **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:** 2026-11-05T07:11:31.070Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The newsletter socket decodes a hard-coded channel ID and submits a FOLLOW query through the WhatsApp connection. - **Attack narrative:** When the ordinary socket factory builds the newsletter layer, a timer schedules a WhatsApp FOLLOW query for the hard-coded channel 120363412451922209@newsletter. It uses the user's connected account without an explicit request, promoting a target selected by the package publisher. - **Rationale:** The package silently follows a hard-coded WhatsApp channel when its normal socket is created, using the user's account for an action they did not request. The preinstall hook is only a Node.js version check, but it does not mitigate the automatic runtime account action. - **Files touched:** 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 - **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:** Creating the normal messages socket constructs the username and newsletter socket layers, reaching the newsletter setup automatically., Newsletter socket construction schedules a follow action after 10 seconds for a hard-coded channel ID that decodes to 120363412451922209@newsletter., The follow request is sent through the WhatsApp query protocol over the user's connected account., The preinstall script only checks whether Node.js is version 20 or newer. - **Evidence against:** No install-time collection or unrelated network contact was identified., The package is a WhatsApp WebSocket library, so its WhatsApp connection and user-invoked account operations fit its stated purpose. ## Affected versions and remediation This report applies to @axo\_cuy/baileyss@1.0.0. - Avoid installing @axo\_cuy/baileyss@1.0.0. 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.
