Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. npm installation imports the entry point and makes an outbound WebSocket connection to WhatsApp. Runtime use automatically enables anti-ban behavior; configured webhooks can transmit alert data. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-09-30T10:34:05.126Z - **Finished:** 2026-09-30T10:35:08.617Z - **Download time:** 260 ms - **Static scan time:** 5849 ms - **AI review time:** 57380 ms - **Total time:** 63491 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:** npm installation imports the entry point and makes an outbound WebSocket connection to WhatsApp. Runtime use automatically enables anti-ban behavior; configured webhooks can transmit alert data. - **Trigger:** Installing the package triggers the self-test; creating a WhatsApp socket triggers the anti-ban wrapper. - **Impact:** Installation contacts WhatsApp without an application call, and runtime behavior may facilitate platform-policy evasion. - **Evidence paths:** package.json, scripts/self-test.js, lib/Socket/index.js, lib/antiban.js - **Review source:** ai\_review - **Reviewed:** 2026-09-30T10:35:08.617Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic install-time connectivity probe and default anti-ban message wrapper. - **Rationale:** The package has real install-time network activity and default anti-ban capability, which are inappropriate for a normal library install. Source inspection found no concrete credential theft, destructive behavior, persistence, or covert hard-coded exfiltration. - **Files touched:** scripts/self-test.js, lib/index.js, lib/Socket/index.js, lib/antiban.js - **Network endpoints:** wss://web.whatsapp.com/ws/chat, https://web.whatsapp.com, https://api.telegram.org ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for block:** Installation automatically runs a self-test that imports the package entry point and opens a WebSocket to WhatsApp., Runtime socket creation enables an aggressive anti-ban wrapper by default, adding message timing and platform-evasion behavior., Webhook delivery can send anti-ban alert data to caller-configured URLs or Telegram. - **Evidence against:** The preinstall hook only enforces the Node.js version., The install-time network target is WhatsApp, consistent with the package's stated WhatsApp Web purpose., No source evidence shows credential harvesting, covert data theft, destructive actions, or self-dependency. ## Affected versions and remediation This report applies to my-baileys@1.0.3. - Avoid installing my-baileys@1.0.3. 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.
