Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The active runtime path performs publisher-selected account actions without user invocation or a consent guard. This is concrete malicious behavior, so publication should be blocked. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-22T03:36:14.661Z - **Finished:** 2026-10-22T03:36:59.375Z - **Download time:** 762 ms - **Static scan time:** 2928 ms - **AI review time:** 41023 ms - **Total time:** 44714 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:** Creating the package’s socket schedules follows of two fixed newsletters on the connected WhatsApp account. - **Trigger:** A consumer creates the exported WhatsApp socket. - **Impact:** The connected account is subscribed to newsletters the consumer did not select. - **Evidence paths:** package.json, lib/index.js, lib/Socket/index.js, lib/Socket/registration.js, lib/Socket/business.js, lib/Socket/messages-recv.js, lib/Socket/messages-send.js, lib/Socket/newsletter.js, lib/Types/Newsletter.js - **Review source:** ai\_review - **Reviewed:** 2026-10-22T03:36:59.375Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The socket setup sends two follow queries for package-selected newsletter IDs after a 90-second delay, with no user action or consent check in this path. - **Attack narrative:** The exported socket factory reaches newsletter socket construction. That constructor schedules two follow operations for fixed newsletter IDs after 90 seconds; the requests use the WhatsApp query path and the package’s follow action identifier. This changes the connected account’s subscriptions without a caller-requested target. - **Rationale:** The active runtime path performs publisher-selected account actions without user invocation or a consent guard. This is concrete malicious behavior, so publication should be blocked. ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** package.json sets lib/index.js as the package entry point., lib/index.js exports the socket factory., The socket factory constructs registration, business, receive, and send layers., The send layer creates the newsletter socket during construction., The newsletter query sends a follow action to WhatsApp with a supplied newsletter ID., Socket construction schedules follows of two fixed newsletter IDs after 90 seconds., The package maps the follow action to its newsletter protocol query ID. ## Affected versions and remediation This report applies to zero2-baileys@3.6.0. - Avoid installing zero2-baileys@3.6.0. 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.
