This is a staged remote-code carrier, but no direct theft or destructive behavior is established in the package. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 91.0% - **Started:** 2026-08-17T12:17:42.935Z - **Finished:** 2026-08-17T12:18:59.745Z - **Download time:** 511 ms - **Static scan time:** 53 ms - **AI review time:** 76245 ms - **Total time:** 76810 ms ## Security analysis ### Published attack-surface review - **Summary:** Opening index.html dynamically loads an obfuscated external loader; the service worker also imports externally selected worker code. This is a staged remote-code carrier, but no direct theft or destructive behavior is established in the package. - **Trigger:** User opens the published HTML application and its service worker runs. - **Impact:** A remote loader publisher can change code executed by visitors after this package is published. - **Evidence paths:** index.html, sw.js, README.md, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-17T12:18:59.745Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated dynamic import and importScripts of remote loader code. - **Rationale:** The package is an obfuscated remote-code carrier with concrete runtime execution of externally sourced code. It lacks install hooks and no direct malicious action is established from the inspected source. - **Files touched:** index.html, sw.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** The HTML entrypoint dynamically imports a loader from obfuscated source URLs and invokes its boot function., The service worker resolves a remote worker version and executes it with importScripts., README describes the package as a static carrier and states release output is obfuscated. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., No package-source evidence of local credential/file harvesting, destructive actions, or AI-agent configuration writes was found. ## Public findings ### 1.
