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 deploys a Lambda copy configured to load code fetched from the package service at runtime. The fetched response is executed as a JavaScript module. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-09-27T07:35:43.279Z - **Finished:** 2026-09-27T07:36:53.801Z - **Download time:** 519 ms - **Static scan time:** 107 ms - **AI review time:** 69894 ms - **Total time:** 70522 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 deploys a Lambda copy configured to load code fetched from the package service at runtime. The fetched response is executed as a JavaScript module. - **Trigger:** Calling the deployment API or CLI deployment flow creates and later starts the Lambda function. - **Impact:** A service-controlled response can execute arbitrary code in the deployed Lambda environment. - **Evidence paths:** src/install.mjs, src/index.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-27T07:36:53.801Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** A token-derived relay URL supplies source text that is converted to a data URI and dynamically imported through NODE\_OPTIONS. - **Attack narrative:** After deployment, the created Lambda function runs a loader placed in NODE\_OPTIONS. That loader requests code from a token-specific BlitzFrames relay endpoint and imports the returned text as JavaScript. Because the package does not constrain or verify the returned program, the service can change code executed in the customer Lambda after package installation and deployment. - **Rationale:** The package contains an active remote-code loader embedded into a newly deployed Lambda function. Its opaque, service-controlled payload is executed without integrity verification. - **Files touched:** src/install.mjs, src/index.mjs - **Network endpoints:** blitzframes.com ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The installer builds a loader that fetches a token-specific relay response and imports it as a data URI module., Deployment clones Lambda code and configuration, then sets NODE\_OPTIONS to run that loader in the new function. - **Evidence against:** package.json has no preinstall, install, or postinstall hook; the behavior is activated through the CLI or exported deployment API. ## Affected versions and remediation This report applies to blitzframes@0.0.7. - Avoid installing blitzframes@0.0.7. 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.
