No concrete attack behavior was identified. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-10T11:38:00.419Z - **Finished:** 2026-10-10T11:38:22.819Z - **Download time:** 510 ms - **Static scan time:** 40 ms - **AI review time:** 21850 ms - **Total time:** 22400 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:** No attack was identified. The SDK loads its widget from Zerohash CDN hosts and sends failure telemetry to Zerohash collectors as part of its widget-loading flow. - **Trigger:** A consumer calls the SDK rendering or script-loading API in a browser. - **Impact:** The package-aligned behavior supports the widget and reports loading failures; no confirmed malicious impact was found. - **Review source:** ai\_review - **Reviewed:** 2026-10-10T11:38:22.819Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The SDK selects a CDN and collector based on environment and JWT region, loads the widget script, and posts failure telemetry containing browser and page metadata. - **Rationale:** Source inspection found a package with no lifecycle scripts and a browser SDK whose external requests support loading its Zerohash widget and reporting load failures. No concrete attack behavior was identified. - **Files touched:** dist/index.js - **Network endpoints:** https://grafana-faro-collector.dev.0hash.com/collect, https://grafana-faro-collector.cert.zerohash.com/collect, https://grafana-faro-collector.zerohash.com/collect, https://grafana-faro-collector.cert.zerohash.eu/collect, https://grafana-faro-collector.zerohash.eu/collect, https://sdk-cdn.dev.0hash.com, https://sdk-cdn.cert.zerohash.com, https://sdk-cdn.zerohash.com, https://sdk-cdn.cert.zerohash.eu, https://sdk-cdn.zerohash.eu, https://sdk-cdn.gating.0hash.com ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json declares dist/index.js as the import entrypoint and has no lifecycle scripts., dist/index.d.ts exposes SDK configuration types; its API describes a JWT supplied by the caller., dist/index.js selects telemetry collectors by environment and derives regional claims from the supplied JWT., The runtime loads the web component from Zerohash CDN URLs when loadScript runs, and passes the selected collector and JWT into that flow., Telemetry posts load-failure information, including browser user agent and page origin, to configured Zerohash collectors. - **Evidence against:** No package-controlled unrelated endpoint, credential harvesting, or install-time execution was identified. ## Affected versions and remediation This report applies to @zerohash-sdk/crypto-buy-js@1.20.0. - Review the evidence and your use of @zerohash-sdk/crypto-buy-js@1.20.0 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.
