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 runtime source establishes an automatic, publisher-selected account action on connection, which is concrete attack behavior under the review policy. The normal WhatsApp destination does not make that unsolicited subscription user-authorized. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-21T12:21:47.355Z - **Finished:** 2026-10-21T12:22:51.425Z - **Download time:** 2542 ms - **Static scan time:** 4291 ms - **AI review time:** 57236 ms - **Total time:** 64070 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 package automatically follows a fixed newsletter on a user’s WhatsApp account after connection. - **Trigger:** A consumer creates a socket and its WhatsApp connection opens. - **Impact:** The user’s account is changed by subscribing to a publisher-selected newsletter without consent to that specific action. - **Evidence paths:** lib/Socket/newsletter.js, lib/Socket/mex.js, lib/Socket/index.js, lib/index.js, lib/Defaults/index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-21T12:22:51.425Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** A connection callback decodes a package-selected newsletter identifier and sends a follow query without a caller-provided target. - **Attack narrative:** Creating a socket leads to an automatic follow request when the WhatsApp connection opens. The callback supplies a fixed, encoded newsletter identifier and sends the follow operation through the authenticated WhatsApp protocol. This changes the consumer’s account by subscribing it to a package-selected newsletter without consent to that action. - **Rationale:** The runtime source establishes an automatic, publisher-selected account action on connection, which is concrete attack behavior under the review policy. The normal WhatsApp destination does not make that unsolicited subscription user-authorized. - **Network endpoints:** wss://web.whatsapp.com/ws/chat ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** When the WhatsApp connection opens, the socket decodes a fixed newsletter identifier and automatically sends a follow request., The request sends the follow operation and its newsletter identifier through the WhatsApp protocol query., The package exports makeWASocket, which constructs the socket layers containing this connection callback., The default socket connects to WhatsApp Web, matching the destination of the account action. - **Evidence against:** The request uses the package’s normal authenticated WhatsApp connection; the inspected code does not show an unrelated recipient or credential transfer. ## Affected versions and remediation This report applies to @elfhkry666/baileys@0.3.26. - Avoid installing @elfhkry666/baileys@0.3.26. 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.
