Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. An explicitly deployed Lambda function downloads and executes JavaScript supplied by the BlitzFrames relay. No automatic package-install attack was identified. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-09-28T11:03:53.349Z - **Finished:** 2026-09-28T11:06:54.056Z - **Download time:** 260 ms - **Static scan time:** 90 ms - **AI review time:** 180356 ms - **Total time:** 180707 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:** An explicitly deployed Lambda function downloads and executes JavaScript supplied by the BlitzFrames relay. No automatic package-install attack was identified. - **Trigger:** The user runs the CLI deployment flow and confirms deployment. - **Impact:** The relay operator can change code executed in the user's deployed Lambda function after deployment. - **Evidence paths:** src/install.mjs, src/index.mjs, src/guided.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-28T11:06:54.056Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The deployment writes a NODE\_OPTIONS import loader that fetches relay content and imports it as JavaScript. - **Rationale:** The behavior is user-invoked and package-aligned, but it installs an opaque remote code loader into a customer Lambda. Static source cannot establish what future relay responses execute. - **Network endpoints:** https://blitzframes.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The package has no install lifecycle hook; it exposes a CLI and library entry point., The loader fetches code from the BlitzFrames relay and dynamically imports the returned text as JavaScript., Deployment copies a Lambda package and sets NODE\_OPTIONS to activate that loader., The guided flow asks for confirmation before deployment. ## Affected versions and remediation This report applies to blitzframes@0.0.3. - Review the evidence and your use of blitzframes@0.0.3 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
