Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. No confirmed attack was identified. The source implements a native CLI installer using package-aligned GitHub releases. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 89.0% - **Started:** 2026-10-02T11:51:35.362Z - **Finished:** 2026-10-02T11:52:23.095Z - **Download time:** 516 ms - **Static scan time:** 39 ms - **AI review time:** 47178 ms - **Total time:** 47733 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:** No confirmed attack was identified. The source implements a native CLI installer using package-aligned GitHub releases. - **Trigger:** npm postinstall invokes ensure mode; invoking the CLI also downloads and installs the native binary. - **Impact:** The native CLI is installed and executed. The inspected source does not establish malicious behavior in that binary. - **Review source:** ai\_review - **Reviewed:** 2026-10-02T11:52:23.095Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The shim downloads a platform asset, writes an executable, and runs its install command. - **Rationale:** Direct inspection shows a transparent, package-aligned native installer without a concrete malicious chain. Scanner similarity labels do not establish an attack, and the unavailable native binary limits conclusions about downstream behavior. - **Files touched:** .local/bin/nur, .local/bin/nur.exe - **Network endpoints:** https://github.com/nuroctane/nur-cli/releases ### Review decision - **Verdict:** Clean - **Confidence:** 89.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json runs bin.js in ensure mode after installation and declares no runtime self-dependency., bin.js downloads platform binaries from the package's nuroctane/nur-cli GitHub releases., Ensure mode skips installation when the native binary already exists., The shim writes the native binary to NUR\_INSTALL\_DIR or the user's .local/bin directory., The downloaded binary runs with the install argument; inspected JavaScript contains no credential harvesting or direct agent configuration mutation. - **Evidence against:** Downloaded native code is executed automatically without checksum verification; its contents are outside this snapshot. ## Affected versions and remediation This report applies to nur-cli@0.43.0. - Review the evidence and your use of nur-cli@0.43.0 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
