Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. An unusual exported subpath executes setup.js on import and drops a staged Deno handler. That handler is designed to collect sensitive local files and disclose them to its HTTP caller. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-09-30T01:14:46.107Z - **Finished:** 2026-09-30T01:15:06.057Z - **Download time:** 515 ms - **Static scan time:** 8 ms - **AI review time:** 19426 ms - **Total time:** 19950 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:** An unusual exported subpath executes setup.js on import and drops a staged Deno handler. That handler is designed to collect sensitive local files and disclose them to its HTTP caller. - **Trigger:** A consumer imports z-deno-truth-ya1t4m/package.json, then uses the dropped handler in a Deno HTTP application. - **Impact:** Potential disclosure of challenge secrets, application backdoor source, and startup configuration if deployed. - **Evidence paths:** package.json, index.js, setup.js - **Review source:** ai\_review - **Reviewed:** 2026-09-30T01:15:06.057Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** staged local-file collection handler written to /tmp - **Rationale:** The package contains a concrete sensitive-file disclosure payload but lacks lifecycle activation, network delivery, or an automatic execution chain. This is an inert staged payload carrier with no benign utility shown. - **Files touched:** setup.js, /tmp/h.tsx, /readflag, /flagserver, /app/backdoor.tsx, /entrypoint.sh ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for block:** setup.js embeds a Deno HTTP handler that reads /readflag, /flagserver, /app/backdoor.tsx, and /entrypoint.sh., The embedded handler returns collected contents in its HTTP response., Importing the exported ./package.json subpath runs setup.js and writes the handler to /tmp/h.tsx. - **Evidence against:** package.json has no preinstall, install, or postinstall hooks., index.js exports an empty object and performs no actions., No network client or automatic execution path was found. ## Affected versions and remediation This report applies to z-deno-truth-ya1t4m@1.0.0. - Avoid installing z-deno-truth-ya1t4m@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.
