Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The sole entry page disguises remote traffic routing behind a Cloudflare challenge. Its obfuscated script retrieves redirect information and navigates the browser to a resolved host. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 95.0% - **Started:** 2026-09-22T10:08:28.032Z - **Finished:** 2026-09-22T10:09:45.130Z - **Download time:** 509 ms - **Static scan time:** 40 ms - **AI review time:** 76548 ms - **Total time:** 77098 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 sole entry page disguises remote traffic routing behind a Cloudflare challenge. Its obfuscated script retrieves redirect information and navigates the browser to a resolved host. - **Trigger:** Opening index.html in a browser; the redirect callback runs after the challenge flow. - **Impact:** A visitor can be silently routed to a remotely selected destination after completing a deceptive verification screen. - **Evidence paths:** index.html - **Review source:** ai\_review - **Reviewed:** 2026-09-22T10:09:45.130Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Inline obfuscated JavaScript fetches a strategy from an API path, resolves a host URL, and calls browser location replacement. - **Attack narrative:** The package contains no usable npm functionality beyond a single HTML page. When opened, it presents a Cloudflare-style challenge, then runs hidden redirect code that obtains routing data and replaces the browser location. This allows the package operator to direct visitors to a destination selected at runtime while concealing that behavior in a large obfuscated script. - **Rationale:** The package is an obfuscated, remotely directed browser redirector presented as a security challenge. This is concrete deceptive traffic-routing behavior, not a package-aligned application. - **Network endpoints:** https://challenges.cloudflare.com, https://challenges.cloudflare.com/turnstile/v0/api.js ### Review decision - **Verdict:** Malicious - **Confidence:** 95.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** Package metadata exposes only an HTML page as its main entry., The page loads Cloudflare Turnstile and invokes a redirect callback after completion., A heavily obfuscated inline script fetches a redirect strategy and replaces the browser location with a resolved host URL., The opaque redirect logic and deceptive challenge page provide a remotely controlled traffic-routing mechanism. - **Evidence against:** No npm lifecycle hook, filesystem mutation, credential harvesting, or child-process execution was found. ## Affected versions and remediation This report applies to ndmcjcxiebysfdb@1.0.1. - Avoid installing ndmcjcxiebysfdb@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.
