Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — Host and local service information is disclosed to an external receiver. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Matched malicious - **Public report status:** Published - **Threat category:** Data Exfiltration - **Selected version:** 0.1.0 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) Trusted malware advisory MAL-2026-17664 identifies this version as malicious. Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The Wix manifest loads bundles that contact a fixed external webhook. The model gathers host and runtime data, probes localhost services, and sends results to that receiver. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-07T08:02:55.105Z - **Finished:** 2026-10-07T08:03:35.168Z - **Download time:** 1287 ms - **Static scan time:** 17 ms - **AI review time:** 38758 ms - **Total time:** 40063 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 Wix manifest loads bundles that contact a fixed external webhook. The model gathers host and runtime data, probes localhost services, and sends results to that receiver. - **Trigger:** Loading the Wix manifest's model or bootstrap bundles. - **Impact:** Host and local service information is disclosed to an external receiver. - **Evidence paths:** rb\_wixui.thunderbolt.manifest.min.json, dist/poc-model.bundle.min.js, dist/poc-bootstrap.bundle.min.js - **Review source:** ai\_review - **Reviewed:** 2026-10-07T08:03:35.168Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The model collects process and network-interface details, reads local network configuration, scans common localhost ports, and posts results to webhook.site. The bootstrap bundle also sends requests to that host. - **Attack narrative:** When the Wix manifest loads its model and bootstrap bundles, they run requests to a fixed webhook.site receiver. The model gathers runtime and host details, reads local network configuration, and probes common localhost ports before sending collected results. This creates an active host data exfiltration path. - **Rationale:** The manifest activates bundles that collect host and local service information and send data to a fixed external receiver. This is active data exfiltration, so the package is malicious. - **Files touched:** dist/poc-model.bundle.min.js, dist/poc-bootstrap.bundle.min.js - **Network endpoints:** https://webhook.site/69bcd627-1871-4dda-b880-83b37ceac418, http://127.0.0.1 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The referenced model bundle collects runtime and host details, including environment data and network interfaces., The model bundle sends collected results to a fixed webhook.site endpoint., The model reads local host and DNS configuration files., The bootstrap bundle makes requests to the same external receiver., The Wix manifest loads the model bundle and bootstrap bundle. ## Affected versions and remediation This report applies to wix-ssr-thunderbolt-grid-polyfill@0.1.0. - Avoid installing wix-ssr-thunderbolt-grid-polyfill@0.1.0. 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.
