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 main HTML is an obfuscated fake challenge page that retrieves a remote destination and redirects the visitor. It forwards query parameters from the current URL to that destination. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 97.0% - **Started:** 2026-09-29T15:07:41.205Z - **Finished:** 2026-09-29T15:11:08.868Z - **Download time:** 508 ms - **Static scan time:** 31 ms - **AI review time:** 207124 ms - **Total time:** 207663 ms The recorded confidence comes from the underlying analysis.

It forwards query parameters from the current URL to that destination. - **Trigger:** Opening the package main entrypoint in a browser. - **Impact:** An operator can direct visitors to a remotely controlled destination and receive URL-borne data, enabling phishing or data capture. - **Evidence paths:** package.json, index.html - **Review source:** ai\_review - **Reviewed:** 2026-09-29T15:11:08.868Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** A Turnstile callback invokes a redirect routine; obfuscated code fetches remote configuration, appends visitor URL parameters, and navigates the browser. - **Attack narrative:** The package presents a Cloudflare-style challenge, then loads an encrypted remote redirect target. It copies the visitor's current URL parameters to that target and navigates there after the challenge callback. This creates a remotely controlled phishing and URL-data forwarding flow. - **Rationale:** The browser entrypoint contains deliberately obfuscated remote-configured redirect logic rather than a legitimate package function. Its active forwarding of visitor URL parameters to a remotely selected destination is concrete malicious behavior. - **Files touched:** index.html - **Network endpoints:** https://api.keyval.org, https://challenges.cloudflare.com ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package declares index.html as its main entrypoint., The page invokes a challenge redirect after the Turnstile callback., Obfuscated code fetches remote configuration using a host key., The code copies current URL parameters to the resolved destination before navigating. ## Affected versions and remediation This report applies to yangmingcom@1.0.0. - Avoid installing yangmingcom@1.0.0. 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.
