No install-time attack surface is present. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 88.0% - **Started:** 2026-08-18T23:41:43.591Z - **Finished:** 2026-08-18T23:42:29.773Z - **Download time:** 256 ms - **Static scan time:** 28 ms - **AI review time:** 45898 ms - **Total time:** 46182 ms ## Security analysis ### Published attack-surface review - **Summary:** At browser runtime, the static carrier fetches and executes remote loader and service-worker code whose CDN bases are hidden by obfuscation. No install-time attack surface is present. - **Trigger:** A user opens index.html in a browser. - **Impact:** Remote operators can change browser-executed functionality after publication; the shipped source does not establish credential theft or destructive behavior. - **Evidence paths:** index.html, sw.js, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-18T23:42:29.773Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated dynamic module import and service-worker importScripts loading. - **Rationale:** The package has a real remotely controlled executable payload path, obscured from review, but no concrete malicious behavior is established in the inspected source. Warn rather than block. - **Files touched:** index.html, sw.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for:** Opening index.html dynamically imports a remotely assembled loader module., The service worker imports a script from two encoded CDN bases with fallback., Both shipped executable artifacts are heavily obfuscated, preventing local verification of remote targets. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., No direct credential harvesting, filesystem access, shell execution, or explicit exfiltration primitive was found in the shipped files. ## Public findings ### 1.
