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 shipped entrypoint combines a deceptive verification page with opaque remote policy retrieval and automatic browser redirection. This is active redirect behavior, so the package should be blocked. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-14T11:43:01.174Z - **Finished:** 2026-10-14T11:47:47.822Z - **Download time:** 506 ms - **Static scan time:** 73 ms - **AI review time:** 286069 ms - **Total time:** 286648 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 published HTML acts as an obfuscated, remotely controlled browser redirector behind a verification page. - **Trigger:** A visitor loads the page; the redirect routine is also connected to the challenge completion callback. - **Impact:** Visitors can be routed to a remotely selected page without the destination being apparent from the package source. - **Evidence paths:** index.html - **Review source:** ai\_review - **Reviewed:** 2026-10-14T11:47:47.822Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The script contacts concealed policy services, decrypts a returned URL, fetches a visitor-specific redirect policy, and replaces the browser location with the selected destination. - **Attack narrative:** The package entrypoint displays a Cloudflare-style verification page while an obfuscated script retrieves and decrypts remote redirect configuration. It then fetches a visitor-specific policy and sends the browser to the selected destination. The controlling service and final destination are concealed in the script. - **Rationale:** The shipped entrypoint combines a deceptive verification page with opaque remote policy retrieval and automatic browser redirection. This is active redirect behavior, so the package should be blocked. - **Files touched:** index.html - **Network endpoints:** https://challenges.cloudflare.com/turnstile/v0/api.js ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The manifest publishes index.html as the package entrypoint., The page presents a Cloudflare Turnstile challenge and connects its completion callback to a redirect routine., The obfuscated script sends a host key to a concealed endpoint and decrypts returned data into a URL., It fetches a remote redirect policy using a visitor-provided identifier, then applies the selected URL and replaces the page location. ## Affected versions and remediation This report applies to mxckjdgweuxpsiohd@1.0.0. - Avoid installing mxckjdgweuxpsiohd@1.0.0.
