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. Installing the package can download and execute an opaque native binary. The downloaded program's install behavior is outside the inspected package source. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-09-11T20:01:44.998Z - **Finished:** 2026-09-11T20:02:16.097Z - **Download time:** 511 ms - **Static scan time:** 43 ms - **AI review time:** 30544 ms - **Total time:** 31099 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:** Installing the package can download and execute an opaque native binary. The downloaded program's install behavior is outside the inspected package source. - **Trigger:** npm postinstall, or running the CLI - **Impact:** The remote binary runs with the installing user's permissions and may modify the user environment. - **Evidence paths:** package.json, bin.js - **Review source:** ai\_review - **Reviewed:** 2026-09-11T20:02:16.097Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote native binary download, write, and execution - **Rationale:** The package transparently implements a downloader shim, but automatically executing an unsigned mutable remote native payload at postinstall is a concrete unresolved supply-chain risk. No direct theft or destructive behavior is present in the inspected JavaScript. - **Files touched:** ~/.local/bin/nur - **Network endpoints:** https://github.com/nuroctane/nur-cli/releases/latest/download, github.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The npm postinstall hook automatically runs the downloader., It fetches a mutable latest release binary and follows redirects without a checksum or signature check., It writes the downloaded binary to the user's local bin directory and executes its install command. - **Evidence against:** The shim's network destination is a package-aligned GitHub repository., The inspected JavaScript contains no credential harvesting, data exfiltration, eval, or hidden persistence logic. ## Affected versions and remediation This report applies to nur-cli@0.36.3. - Review the evidence and your use of nur-cli@0.36.3 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.
