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 package payload is an obfuscated browser page that gates a dynamically selected redirect behind a Turnstile challenge. No legitimate package functionality is present. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 93.0% - **Started:** 2026-09-22T04:24:52.047Z - **Finished:** 2026-09-22T04:34:11.082Z - **Download time:** 508 ms - **Static scan time:** 41 ms - **AI review time:** 558486 ms - **Total time:** 559035 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 package payload is an obfuscated browser page that gates a dynamically selected redirect behind a Turnstile challenge. No legitimate package functionality is present. - **Trigger:** A visitor loads index.html and completes the Turnstile challenge. - **Impact:** Visitors can be routed to a remotely selected destination after completing the challenge, enabling concealed traffic redirection. - **Evidence paths:** index.html - **Review source:** ai\_review - **Reviewed:** 2026-09-22T04:34:11.082Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The inline script invokes a redirect callback and requests a policy redirect using a cid parameter; its host resolution and redirect logic are deliberately obfuscated. - **Attack narrative:** The package is a single-page challenge gate rather than a usable npm library. Loading it fetches Turnstile, and successful completion calls an obfuscated redirect routine. The page also contains obfuscated logic for obtaining a policy redirect based on a cid value, allowing a remote destination to control visitor routing. - **Rationale:** The package actively implements concealed, challenge-gated remote redirection in its only payload. Its opaque implementation and lack of legitimate package behavior support blocking it as malware. - **Files touched:** index.html - **Network endpoints:** https://challenges.cloudflare.com, https://challenges.cloudflare.com/turnstile/v0/api.js ### Review decision - **Verdict:** Malicious - **Confidence:** 93.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package declares index.html as its only published main file., The page loads Cloudflare Turnstile and invokes a redirect callback when the challenge completes., An obfuscated inline script defines a policy redirect request using a caller-provided cid value. ## Affected versions and remediation This report applies to ndmcjcxiebysfdb@1.0.2. - Avoid installing ndmcjcxiebysfdb@1.0.2. 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.
