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. Installing the package imports its library and makes an unsolicited WebSocket connection to WhatsApp. At runtime it also enables message pacing and anti-ban behavior by default. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-09-30T10:34:03.841Z - **Finished:** 2026-09-30T10:35:08.617Z - **Download time:** 255 ms - **Static scan time:** 2179 ms - **AI review time:** 62340 ms - **Total time:** 64776 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:** Installing the package imports its library and makes an unsolicited WebSocket connection to WhatsApp. At runtime it also enables message pacing and anti-ban behavior by default. - **Trigger:** npm install, or creation of a WhatsApp socket at runtime. - **Impact:** Installation leaks that the host installed the package to WhatsApp and may fail or delay in restricted environments; runtime behavior changes message sending unless disabled. - **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 socket wrapper. - **Rationale:** The source shows unconsented install-time network activity and a platform-evasion-oriented capability enabled by default, which warrants a warning. It does not show a payload download, secret harvesting, destructive action, or attacker-controlled endpoint. - **Files touched:** scripts/self-test.js, lib/index.js, lib/Socket/index.js, lib/antiban.js - **Network endpoints:** wss://web.whatsapp.com/ws/chat ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for block:** The package runs a preinstall check and a postinstall program automatically., The postinstall program imports the full library and opens a WebSocket to WhatsApp during installation., Runtime socket creation enables an aggressive anti-ban wrapper unless the consumer explicitly disables it., The anti-ban module can send alert data to user-configured webhooks, including Telegram. - **Evidence against:** The preinstall hook only rejects Node versions below 20., The install-time WebSocket target is a fixed WhatsApp host; no credential collection or upload was found., No self-dependency, evaluator, shell execution, or foreign configuration mutation was found., Webhook delivery requires caller-provided configuration. ## Affected versions and remediation This report applies to my-baileys@1.0.5. - Avoid installing my-baileys@1.0.5. 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.
