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 explicit deployment installs a runtime loader into an AWS Lambda function. No install-time attack was identified. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-09-28T11:03:29.678Z - **Finished:** 2026-09-28T11:04:28.110Z - **Download time:** 510 ms - **Static scan time:** 79 ms - **AI review time:** 57843 ms - **Total time:** 58432 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 explicit deployment installs a runtime loader into an AWS Lambda function. No install-time attack was identified. - **Trigger:** The user runs the BlitzFrames deployment flow. - **Impact:** The relay operator can change code executed in the user's deployed Lambda function. - **Evidence paths:** src/install.mjs, src/index.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-28T11:04:28.110Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The deployed function receives NODE\_OPTIONS that fetches and dynamically imports relay-provided JavaScript. - **Rationale:** The source establishes a real remote runtime-code loading path, but not a demonstrated malicious payload or covert install-time attack. This warrants a warning for dangerous capability rather than a publication block. - **Network endpoints:** https://blitzframes.com/api/relay.mjs/\ ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The package exposes a CLI and library entrypoint without an automatic lifecycle hook., Its installer value fetches code from the BlitzFrames relay and dynamically imports it as a data URL., Deployment writes that installer value to NODE\_OPTIONS on a copied AWS Lambda function. - **Evidence against:** The remote loader is activated through an explicit deployment command rather than package installation., No source evidence showed credential forwarding to the relay or destructive local behavior. ## Affected versions and remediation This report applies to blitzframes@0.0.1. - Review the evidence and your use of blitzframes@0.0.1 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.
