The package itself is an obfuscated staged payload carrier rather than a self-contained application. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 91.0% - **Started:** 2026-08-17T12:17:42.927Z - **Finished:** 2026-08-17T12:18:59.864Z - **Download time:** 511 ms - **Static scan time:** 53 ms - **AI review time:** 76372 ms - **Total time:** 76937 ms ## Security analysis ### Published attack-surface review - **Summary:** On browser load, the carrier dynamically imports a remote loader and its service worker imports a remote worker selected at runtime. The package itself is an obfuscated staged payload carrier rather than a self-contained application. - **Trigger:** A user serves or opens index.html in a browser. - **Impact:** Remote CDN content can change browser-executed application and service-worker behavior after package publication. - **Evidence paths:** index.html, sw.js, README.md, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-17T12:18:59.864Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Runtime remote-module and service-worker loading from obfuscated CDN sources. - **Rationale:** This is a concrete staged-payload architecture with mutable remote execution, but there is no install-time behavior, local harvesting, or demonstrated malicious payload in the package. Warn rather than block. - **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:** Medium - **Evidence for:** Runtime dynamically imports externally constructed loader sources and invokes their boot function., Service worker resolves a worker version through XMLHttpRequest then imports remote code with importScripts., README describes this package as an obfuscated static carrier whose loader follows a latest tag. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., Published files are limited to index.html and sw.js; no local credential or filesystem APIs were found., README states network events expose only coarse transport state, not ICE candidates or addresses. ## Public findings ### 1.
