The remote URLs are obfuscated, so exact hosts are not recoverable from source without execution. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 91.0% - **Started:** 2026-08-18T23:41:43.591Z - **Finished:** 2026-08-18T23:43:00.650Z - **Download time:** 252 ms - **Static scan time:** 30 ms - **AI review time:** 76776 ms - **Total time:** 77059 ms ## Security analysis ### Published attack-surface review - **Summary:** Opening the published HTML dynamically imports an external loader; the service worker also imports external code. The remote URLs are obfuscated, so exact hosts are not recoverable from source without execution. - **Trigger:** A user serves or opens index.html in a browser. - **Impact:** Third-party CDN-controlled code executes in the page and service-worker contexts. - **Evidence paths:** index.html, sw.js, README.md, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-18T23:43:00.650Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated runtime remote-module and service-worker loading. - **Rationale:** Source establishes a remote executable-code loading chain but does not establish a concrete malicious payload or install-time attack. This is a real unresolved supply-chain risk, warranting a warning rather than a 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:** Low - **Evidence for:** Runtime dynamically imports remotely constructed loader sources., Service worker imports code from obfuscated CDN base URLs., Published artifact is heavily obfuscated and identified as a YuriRTC carrier, not a math package. - **Evidence against:** No npm preinstall, install, or postinstall lifecycle hook., No direct credential harvesting, filesystem access, shell execution, or exfiltration is present in the package files. ## Public findings ### 1.
