Installing the package can add persistent automatic execution to a third-party AI-agent control surface without an explicit setup command. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.9.7 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. LPM flags this version as an AI-agent control-surface risk. An automatic install hook modifies the user's Claude Code configuration. It installs commands that run ccclub after Claude Code events. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-29T07:38:53.825Z - **Finished:** 2026-09-29T07:39:56.119Z - **Download time:** 252 ms - **Static scan time:** 754 ms - **AI review time:** 61288 ms - **Total time:** 62294 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:** An automatic install hook modifies the user's Claude Code configuration. It installs commands that run ccclub after Claude Code events. - **Trigger:** npm post-install execution when the settings file exists. - **Impact:** Installing the package can add persistent automatic execution to a third-party AI-agent control surface without an explicit setup command. - **Evidence paths:** package.json, scripts/postinstall.cjs - **Review source:** ai\_review - **Reviewed:** 2026-09-29T07:39:56.119Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The script inserts managed SessionEnd and Stop hooks and writes the Claude Code settings file; it can also update an existing macOS launch agent. - **Attack narrative:** The package automatically runs a post-install script. When Claude Code configuration is present, that script adds ccclub sync commands to SessionEnd and Stop hooks and saves the modified configuration. This creates automatic execution in a foreign AI-agent control surface during package installation. It also updates an existing macOS launch agent that repeatedly invokes ccclub sync. - **Rationale:** The automatic post-install mutation of Claude Code hooks is an unconsented modification of a broad AI-agent control surface. This meets the install-control-surface block policy. - **Files touched:** .claude/settings.json, Library/LaunchAgents/dev.ccclub.sync.plist ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package registers scripts/postinstall.cjs as an automatic post-install hook., The post-install script adds ccclub commands to Claude Code SessionEnd and Stop hooks, then writes the settings file., The post-install entrypoint invokes the hook update while suppressing errors., On macOS, the script can rewrite an existing launch agent that runs ccclub sync periodically. - **Evidence against:** The inspected credential use sends a Claude token to Anthropic's usage endpoint, not an unrelated endpoint. ## Affected versions and remediation This report applies to ccclub@0.9.7. - Avoid installing ccclub@0.9.7. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
