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 package injects an unpinned remote-code loader into a newly created AWS Lambda function. The retrieved code executes with the copied function configuration and role. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 93.0% - **Started:** 2026-09-27T07:35:47.040Z - **Finished:** 2026-09-27T07:36:48.627Z - **Download time:** 500 ms - **Static scan time:** 142 ms - **AI review time:** 60944 ms - **Total time:** 61587 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 injects an unpinned remote-code loader into a newly created AWS Lambda function. The retrieved code executes with the copied function configuration and role. - **Trigger:** A user invokes the deployment functionality through the CLI or exported API. - **Impact:** The endpoint can change code executed in the customer's Lambda environment, including code with that function's AWS permissions. - **Evidence paths:** src/install.mjs, src/index.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-27T07:36:48.627Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The deployment assigns NODE\_OPTIONS to a data-module loader that fetches, writes, and imports code from blitzframes.com. - **Attack narrative:** On deployment, the package creates a Lambda variant and sets NODE\_OPTIONS to an embedded loader. When that Lambda starts, the loader retrieves JavaScript from a package-controlled endpoint, stores it in the temporary directory, and imports it. There is no integrity pinning or local implementation of that retrieved module. The endpoint can therefore supply code that executes in the Lambda function under the copied role and environment. - **Rationale:** This is an active remote-code execution path in a customer AWS function, not merely a downloadable artifact. Explicit deployment invocation does not constrain the package-controlled endpoint or pin the executed code. - **Files touched:** src/install.mjs, src/index.mjs - **Network endpoints:** https://blitzframes.com/api/relay.mjs/ ### Review decision - **Verdict:** Malicious - **Confidence:** 93.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package builds a loader that fetches a token-addressed remote module, writes it to temporary storage, and imports it at runtime., Deployment copies a Lambda function and sets its NODE\_OPTIONS environment variable to that loader, causing remote code to run in the copied function's context. - **Evidence against:** There is no npm install lifecycle hook; the deployment path is reached through the CLI or exported API., The guided CLI asks before deploying a BlitzFrames function. ## Affected versions and remediation This report applies to blitzframes@0.11.5. - Avoid installing blitzframes@0.11.5. 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.
