Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The obfuscated remote destination lookup, automatic redirect, and visitor-parameter forwarding establish an active traffic-redirection behavior behind a challenge-style page. This is malicious behavior rather than an inert payload carrier. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-15T07:54:58.843Z - **Finished:** 2026-10-15T07:56:41.665Z - **Download time:** 763 ms - **Static scan time:** 35 ms - **AI review time:** 102023 ms - **Total time:** 102822 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 serves an obfuscated page that retrieves a destination from a remote service and redirects visitors while forwarding their URL parameters. A Cloudflare-style challenge screen precedes the redirect. - **Trigger:** Opening index.html in a browser starts the remote lookup and automatic redirect. - **Impact:** Visitors can be routed to a remotely selected destination without an explicit navigation choice, with their URL parameters included. - **Evidence paths:** index.html - **Review source:** ai\_review - **Reviewed:** 2026-10-15T07:56:41.665Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The script sends an obfuscated key to a keyval.org endpoint, decrypts the returned destination, copies current URL parameters to it, and navigates the browser there. - **Attack narrative:** The page imitates a Cloudflare challenge but runs obfuscated code that obtains an encrypted destination from a remote service and redirects the visitor automatically. It also forwards the current page’s URL parameters to that destination. This provides a concealed traffic-routing surface; the actual redirect destination is remotely selected. - **Rationale:** The obfuscated remote destination lookup, automatic redirect, and visitor-parameter forwarding establish an active traffic-redirection behavior behind a challenge-style page. This is malicious behavior rather than an inert payload carrier. - **Files touched:** index.html - **Network endpoints:** https://challenges.cloudflare.com/turnstile/v0/api.js, https://api.keyval.org/get ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package declares index.html as its main entry point., The page presents a Cloudflare Turnstile challenge while loading Cloudflare’s script., Obfuscated code sends a key to a keyval.org endpoint, decrypts the response, and constructs a destination URL., The script copies parameters from the current page URL to the destination and navigates the browser there., The page calls the redirect automatically after a short delay. ## Affected versions and remediation This report applies to vjkpwjxbvndelta@1.0.1. - Avoid installing vjkpwjxbvndelta@1.0.1.
