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 source confirms automatic, publisher-selected account actions when the socket is created. This concrete behavior supports blocking publication regardless of whether the install hook is benign. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-27T11:27:53.763Z - **Finished:** 2026-10-27T11:32:10.643Z - **Download time:** 771 ms - **Static scan time:** 1572 ms - **AI review time:** 254536 ms - **Total time:** 256880 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 construction automatically makes three newsletter follow requests from the authenticated WhatsApp account. - **Trigger:** A consumer creates the package's socket through its exported factory. - **Impact:** The account is made to follow publisher-selected newsletters without the caller requesting those actions. - **Evidence paths:** package.json, lib/index.js, lib/Socket/index.js, lib/Socket/communities.js, lib/Socket/business.js, lib/Socket/messages-recv.js, lib/Socket/messages-send.js, lib/Socket/newsletter.js - **Review source:** ai\_review - **Reviewed:** 2026-10-27T11:32:10.643Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Nested socket constructors reach the newsletter socket, which schedules follow queries for three hardcoded newsletter identifiers. - **Attack narrative:** Creating the exported socket reaches newsletter socket construction through the package's socket layers. That constructor schedules three delayed newsletter queries using the follow action and fixed newsletter identifiers. The queries use the authenticated WhatsApp connection, so consumers can unknowingly cause their accounts to follow those newsletters. - **Rationale:** The source confirms automatic, publisher-selected account actions when the socket is created. This concrete behavior supports blocking publication regardless of whether the install hook is benign. - **Files touched:** package.json, lib/index.js, lib/Socket/index.js, lib/Socket/communities.js, lib/Socket/business.js, lib/Socket/messages-recv.js, lib/Socket/messages-send.js, lib/Socket/newsletter.js ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package entry point exports the socket factory, which reaches newsletter socket construction through its socket layers., Newsletter socket construction schedules three requests using the follow action and hardcoded newsletter identifiers, without a caller request or consent check., Those requests use the WhatsApp newsletter query protocol, making the authenticated account perform publisher-selected follows. - **Evidence against:** The manifest's preinstall command only checks the Node.js version; the confirmed behavior is triggered later when the socket is constructed. ## Affected versions and remediation This report applies to @lsqltmux-code/baileys@8.5.3. - Avoid installing @lsqltmux-code/baileys@8.5.3. 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.
