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 declared browser entrypoint disguises an obfuscated redirect flow as a Cloudflare challenge. No npm install-time attack was identified. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 93.0% - **Started:** 2026-09-22T00:03:14.749Z - **Finished:** 2026-09-22T00:04:17.345Z - **Download time:** 506 ms - **Static scan time:** 41 ms - **AI review time:** 62047 ms - **Total time:** 62596 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 declared browser entrypoint disguises an obfuscated redirect flow as a Cloudflare challenge. No npm install-time attack was identified. - **Trigger:** A user opens index.html in a browser and the challenge flow runs. - **Impact:** A visitor can be silently sent to an undisclosed remote destination after interacting with or waiting on the challenge page. - **Evidence paths:** index.html - **Review source:** ai\_review - **Reviewed:** 2026-09-22T00:04:17.345Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The script resolves a hidden destination, appends visitor parameters, and calls the browser replace operation to navigate there. - **Attack narrative:** This randomly named package exposes only an HTML challenge page. Its heavily obfuscated script uses a Cloudflare Turnstile presentation and automatically redirects the browser to a dynamically resolved URL after adding visitor parameters. The concealed redirect destination prevents a user from assessing where the page sends them. - **Rationale:** The package contains a concealed browser-redirect mechanism behind a challenge-themed page, which is concrete deceptive behavior. Although it has no install hook, the active entrypoint is structured to route visitors to an obscured remote destination. - **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 an HTML file as its only main entrypoint., The entrypoint loads Cloudflare Turnstile while presenting a challenge page., Obfuscated browser code appends visitor parameters and replaces the current page with a resolved remote URL. - **Evidence against:** There are no npm lifecycle hooks or dependencies in the manifest., No local file modification or credential-reading API was identified. ## Affected versions and remediation This report applies to fdhcxvnwhjiofv@1.0.0. - Avoid installing fdhcxvnwhjiofv@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.
