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. Install and the CLI entry both download an unsigned native binary from GitHub Releases and run it. There is no integrity check, latest is tried first, and redirects are not pinned to GitHub. The opaque nur install step can change the user environment beyond the npm package itself. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 84.0% - **Started:** 2026-09-19T04:38:55.748Z - **Finished:** 2026-09-19T04:41:06.573Z - **Download time:** 515 ms - **Static scan time:** 37 ms - **AI review time:** 130272 ms - **Total time:** 130825 ms The recorded confidence comes from the underlying analysis.

There is no integrity check, latest is tried first, and redirects are not pinned to GitHub. The opaque nur install step can change the user environment beyond the npm package itself. - **Trigger:** npm install runs postinstall (node bin.js --ensure); npx nur-cli or the bin entry runs the same downloader without --ensure. - **Impact:** Native code runs as the installing user and may change PATH and other local setup; a redirected or swapped release asset would also run. - **Evidence paths:** package.json, bin.js - **Review source:** ai\_review - **Reviewed:** 2026-09-19T04:41:06.573Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall remote binary download and execute - **Rationale:** This is a first-party GitHub-release installer shim, not a hidden stealer, but postinstall still fetches and runs an unsigned latest binary with open redirects and then executes nur install. That is dangerous install-time capability and should warn, not pass clean or block as proven malware. - **Files touched:** ~/.local/bin/nur, ~/.local/bin/nur.exe - **Network endpoints:** https://github.com/nuroctane/nur-cli/releases/ ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** package.json postinstall runs node bin.js --ensure on every npm install and ignores failure., bin.js downloads a native GitHub Releases asset, trying latest first then a version fallback, with no checksum or signature check., The downloaded bytes are written to the user local bin path and marked executable., The new binary is executed immediately with argument install, which the comments say wires PATH and ecosystem packs., The downloader follows Location redirects over http or https with no host allowlist. - **Evidence against:** The download host is hardcoded to github.com/nuroctane/nur-cli, matching the package name and documented shim purpose., Source is short and unobfuscated: no eval, no secret harvesting, and the only env var is NUR\_INSTALL\_DIR., --ensure skips the download when a binary is already present. ## Affected versions and remediation This report applies to nur-cli@0.30.0. - Review the evidence and your use of nur-cli@0.30.0 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.
