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 package performs a publisher-chosen WhatsApp account action by default: it follows a hard-coded newsletter when the socket connects. The README discloses the behavior and provides an opt-out, but the package rules classify default account actions toward publisher-selected targets as malicious. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-11-03T12:11:25.554Z - **Finished:** 2026-11-03T12:12:08.508Z - **Download time:** 1518 ms - **Static scan time:** 3867 ms - **AI review time:** 37568 ms - **Total time:** 42954 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 library follows a publisher-selected WhatsApp newsletter using the user's account by default. - **Trigger:** Creating a socket and then reaching the open connection state; the follow occurs after a delay. - **Impact:** The user's WhatsApp account is made to follow the publisher's channel without an explicit request for that account action. - **Evidence paths:** lib/Alex/auto-follow.js, lib/Socket/index.js, lib/Defaults/index.js - **Review source:** ai\_review - **Reviewed:** 2026-11-03T12:12:08.508Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The default socket factory attaches a handler that calls \`newsletterFollow\` for the hard-coded newsletter unless the caller opts out or supplies another target. - **Attack narrative:** When a socket is created, the package attaches an auto-follow handler. Once the WhatsApp connection opens, it follows the hard-coded publisher newsletter after a delay. The README discloses the behavior and offers an opt-out, but the account action still happens by default using the user's credentials toward a publisher-chosen target. - **Rationale:** The package performs a publisher-chosen WhatsApp account action by default: it follows a hard-coded newsletter when the socket connects. The README discloses the behavior and provides an opt-out, but the package rules classify default account actions toward publisher-selected targets as malicious. - **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 default newsletter target is \`120363404367589225@newsletter\`., An unset \`autoFollowNewsletter\` option resolves to the default target., The socket factory attaches the auto-follow handler when creating a socket., After the WhatsApp connection opens, the handler follows the target newsletter. - **Evidence against:** The README discloses that the package auto-follows the publisher's channel and documents how to disable or change it., The preinstall script only checks the Node.js major version and exits on versions below 20. ## Affected versions and remediation This report applies to @alexiddev/baileys@1.0.1. - Avoid installing @alexiddev/baileys@1.0.1. 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.
