AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The default socket construction schedules a follow of a hard-coded WhatsApp newsletter through the user's session, without consent. This is an unrequested account action toward a publisher-selected target and meets the malicious account-action rule. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-11-05T07:09:58.428Z - **Finished:** 2026-11-05T07:11:25.751Z - **Download time:** 2070 ms - **Static scan time:** 1771 ms - **AI review time:** 83481 ms - **Total time:** 87323 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 default WhatsApp socket automatically attempts to follow a publisher-selected newsletter. - **Trigger:** Calling makeWASocket(config) constructs the default socket; the follow is scheduled for 10 seconds later. - **Impact:** The user's authenticated WhatsApp account may be made to follow the selected newsletter without their request. - **Evidence paths:** lib/Socket/index.js, lib/Socket/business.js, lib/Socket/messages-send.js, lib/Socket/username.js, lib/Socket/newsletter.js, lib/Socket/mex.js - **Review source:** ai\_review - **Reviewed:** 2026-11-05T07:11:25.751Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** makeNewsletterSocket decodes a hard-coded newsletter ID and sends it with the FOLLOW query, without a user request or consent check. - **Attack narrative:** When an application creates the package's default WhatsApp socket, the constructor chain reaches makeNewsletterSocket. It schedules a FOLLOW request for a hard-coded newsletter ID after 10 seconds and sends it through the WhatsApp query path. This uses the user's account for an action toward a target selected by the package publisher, without an explicit request. - **Rationale:** The default socket construction schedules a follow of a hard-coded WhatsApp newsletter through the user's session, without consent. This is an unrequested account action toward a publisher-selected target and meets the malicious account-action rule. - **Files touched:** lib/Socket/index.js, lib/Socket/business.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:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package entry point exports makeWASocket, whose default socket construction builds the communities and business layers., That default construction reaches makeMessagesSocket, which creates makeUsernameSocket; makeUsernameSocket creates makeNewsletterSocket., makeNewsletterSocket schedules an unconditional FOLLOW request after 10 seconds for a hard-coded, base64-encoded newsletter ID., The follow is sent through the WhatsApp w:mex query path using the socket query., The preinstall script only rejects Node versions below 20; it does not explain or gate the automatic follow. - **Evidence against:** The package describes itself as a WebSocket library for interacting with WhatsApp, and newsletter-follow functionality fits that purpose when requested by the caller., The package has a preinstall hook, but its script only checks the Node.js version. ## Affected versions and remediation This report applies to @axo\_cuy/baileyss@3.0.1. - Avoid installing @axo\_cuy/baileyss@3.0.1. 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.
