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 package entrypoint is a browser page that disguises its behavior behind a challenge interface and obfuscated script. It decrypts configuration and redirects the visitor to an undisclosed destination. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-09-29T15:07:59.047Z - **Finished:** 2026-09-29T15:11:24.436Z - **Download time:** 510 ms - **Static scan time:** 35 ms - **AI review time:** 204843 ms - **Total time:** 205389 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 package entrypoint is a browser page that disguises its behavior behind a challenge interface and obfuscated script. It decrypts configuration and redirects the visitor to an undisclosed destination. - **Trigger:** Opening index.html in a browser. - **Impact:** A visitor can be sent to a remote destination that is intentionally hidden from static inspection; no credential theft was confirmed. - **Evidence paths:** index.html - **Review source:** ai\_review - **Reviewed:** 2026-09-29T15:11:24.436Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated JavaScript imports a cryptographic key, decrypts a URL, and invokes a delayed redirect routine. - **Rationale:** The deliberately concealed redirect chain is a real unresolved browser-side payload path, but the inspected code does not prove the remote destination performs a concrete attack. This warrants a warning rather than a block. - **Files touched:** index.html - **Network endpoints:** https://challenges.cloudflare.com/turnstile/v0/api.js ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The manifest exposes index.html as the package entrypoint., The entry page contains heavily obfuscated code that decodes encrypted data and imports a Web Crypto key., The page schedules a redirect to a concealed host after presenting a challenge interface. - **Evidence against:** No install lifecycle hook, file harvesting, or credential collection was identified in the inspected files., The only visible external resource is Cloudflare Turnstile; the concealed redirect destination could not be statically resolved. ## Affected versions and remediation This report applies to yangmingcom@1.0.1. - Review the evidence and your use of yangmingcom@1.0.1 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.
