Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The browser entrypoint is an obfuscated challenge page that obtains an encrypted remote destination and redirects there. It carries the visitor's original query parameters to that destination. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-09-29T06:30:13.612Z - **Finished:** 2026-09-29T06:31:32.429Z - **Download time:** 260 ms - **Static scan time:** 42 ms - **AI review time:** 78514 ms - **Total time:** 78817 ms The recorded confidence comes from the underlying analysis.

It carries the visitor's original query parameters to that destination. - **Trigger:** Opening or importing the declared HTML entrypoint in a browser. - **Impact:** Query-string data, including any embedded tokens, can be disclosed to a remotely controlled destination and the visitor can be routed to attacker-selected content. - **Evidence paths:** index.html - **Review source:** ai\_review - **Reviewed:** 2026-09-29T06:31:32.429Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated code fetches a remote response, decrypts it into a URL, appends current URL parameters, and changes browser location. - **Attack narrative:** The only package entrypoint presents a challenge-themed browser page. Its hidden script contacts an obscured endpoint, decrypts a supplied destination URL, forwards existing URL parameters, and redirects the visitor. The destination is not constrained in the source, enabling remote control of the redirect target and disclosure of query data. - **Rationale:** The active, obfuscated remote redirect chain and forwarding of visitor query parameters establish a concrete malicious browser payload. The code provides no source-visible destination allowlist. - **Network endpoints:** https://challenges.cloudflare.com ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The declared entrypoint is index.html., The entrypoint sends a host value to an obfuscated remote endpoint., It decrypts the response and constructs a destination URL from it., It forwards existing URL parameters to that destination before redirecting the browser. ## Affected versions and remediation This report applies to ndmctsgh\_edu\_tw@1.0.1. - Avoid installing ndmctsgh\_edu\_tw@1.0.1. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
