This report does not record a matching static-policy override reason. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. No confirmed malicious attack surface. The postinstall hook performs platform-specific local launcher setup within the package directory. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 95.0% - **Started:** 2026-08-18T01:00:43.715Z - **Finished:** 2026-08-18T01:00:49.553Z - **Download time:** 764 ms - **Static scan time:** 5074 ms - **AI review time:** 36814 ms - **Total time:** 5838 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 malicious attack surface. The postinstall hook performs platform-specific local launcher setup within the package directory. - **Trigger:** npm postinstall - **Impact:** Replaces this package's bin/claudin.exe launcher and may create bin/vendor. - **Evidence paths:** package.json, install.cjs, cli-wrapper.cjs, dist/cli.mjs, dist/chunks/bridgeMain-1.1.16-04vqwa21.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-18T01:00:49.553Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** local hardlink/copy of same-vendor optional binary and vendored helper - **Rationale:** The install hook is package-scoped native-binary setup, not an unconsented mutation of a foreign AI-agent control surface. Runtime agent, OAuth, network, and remote-control capabilities are aligned with the explicitly invoked CLI and do not establish an install-time malicious chain. - **Files touched:** bin/claudin.exe, bin/vendor ### Review decision - **Verdict:** Clean - **Confidence:** 92.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Final policy explanation:** The AI recommended clean, but the final policy action is warn. This report does not record a matching static-policy override reason. - **Evidence against:** package.json runs only install.cjs at postinstall., install.cjs selects a same-vendor optional platform package and replaces only bin/claudin.exe., Postinstall copies vendored ripgrep only beneath this package's bin/vendor directory., cli-wrapper.cjs runs the selected local binary or bundled dist/cli.mjs; no remote payload retrieval is present., Remote-control and OAuth code are runtime CLI features, not install-time behavior. ## Affected versions and remediation This report applies to @claudiolabs/claudin@1.1.16. - Review the evidence and your use of @claudiolabs/claudin@1.1.16 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.
