Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. Installation automatically downloads an opaque native executable, stores it outside the package, and executes its install command. The payload is not integrity-pinned and its behavior cannot be verified from this snapshot. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 93.0% - **Started:** 2026-09-16T06:21:38.931Z - **Finished:** 2026-09-16T06:22:26.479Z - **Download time:** 789 ms - **Static scan time:** 41 ms - **AI review time:** 46718 ms - **Total time:** 47548 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:** Installation automatically downloads an opaque native executable, stores it outside the package, and executes its install command. The payload is not integrity-pinned and its behavior cannot be verified from this snapshot. - **Trigger:** npm postinstall, or a user invoking the CLI. - **Impact:** A changed or compromised release asset can run with the installing user's privileges and alter the user's environment. - **Evidence paths:** package.json, bin.js - **Review source:** ai\_review - **Reviewed:** 2026-09-16T06:22:26.479Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote native binary download followed by automatic execution. - **Rationale:** This is an automatic remote-code-execution installer with an opaque, unpinned native payload. The visible shim does not itself show credential theft or destructive code, so the risk is unresolved rather than proven malicious. - **Files touched:** ~/.local/bin/nur, ~/.local/bin/nur.exe - **Network endpoints:** github.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The postinstall hook automatically starts the downloader., It downloads a native binary from GitHub Release URLs, including an unpinned latest release., The only validation is a minimum size check before the binary is written and executed with install., The executed binary and its install behavior are absent from this package, leaving its effects unverifiable. - **Evidence against:** The shim uses a hard-coded GitHub repository rather than collecting credentials or sending environment data., No source code in the package harvests files, reads secrets, or uses eval-like execution., The network and process behavior is limited to installing the stated native CLI payload. ## Affected versions and remediation This report applies to nur-cli@0.32.0. - Review the evidence and your use of nur-cli@0.32.0 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.
