No install-time local attack was identified. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Matched malicious - **Public report status:** Published - **Threat category:** Data Exfiltration - **Selected version:** 1.0.0 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) Trusted malware advisory MAL-2026-16400 identifies this version as malicious. 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 only package payload is a heavily obfuscated web page that presents a Cloudflare-style challenge and redirects the visitor. The redirect destination and visitor parameters are resolved by opaque code. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-09-22T09:51:40.794Z - **Finished:** 2026-09-22T10:01:01.007Z - **Download time:** 507 ms - **Static scan time:** 32 ms - **AI review time:** 559674 ms - **Total time:** 560213 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 only package payload is a heavily obfuscated web page that presents a Cloudflare-style challenge and redirects the visitor. The redirect destination and visitor parameters are resolved by opaque code. - **Trigger:** A user opens index.html; challenge completion invokes the redirect callback. - **Impact:** A visitor can be tracked and sent to an undisclosed remote destination. No install-time local attack was identified. - **Evidence paths:** index.html - **Review source:** ai\_review - **Reviewed:** 2026-09-22T10:01:01.007Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The script appends visitor parameters to a constructed URL and calls its redirect routine after resolving a host through opaque fetch logic. - **Attack narrative:** When opened, the page loads Turnstile, runs an obfuscated callback, constructs a destination URL, appends visitor data, and redirects the browser. The opaque remote-resolution path prevents the recipient and exact exported data from being audited statically. - **Rationale:** This is an active, obfuscated browser redirect and visitor-data forwarding payload with no stated package functionality. It is not normal npm package behavior and conceals its remote destination. - **Network endpoints:** https://challenges.cloudflare.com/turnstile/v0/api.js ### Review decision - **Verdict:** Malicious - **Confidence:** 91.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package declares an HTML document as its sole main entrypoint., Opening the entrypoint invokes an opaque callback after a Turnstile challenge completes., The obfuscated script builds a destination URL, appends visitor parameters, and invokes a host-redirect routine. - **Evidence against:** No npm lifecycle hook, dependency, or local filesystem mutation is declared., No explicit non-Cloudflare network host is readable without evaluating the obfuscated script. ## Affected versions and remediation This report applies to ndmcjcxiebysfdb@1.0.0. - Avoid installing ndmcjcxiebysfdb@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.
