Claude Code events can automatically invoke a version-pinned package command; the LaunchAgent can invoke it every five minutes. - **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:** 0.9.5 - **Selected version is latest:** No - **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. Installing the package mutates an existing Claude Code configuration to add automatic commands. On macOS it can also replace and reload a persistent LaunchAgent. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-13T23:30:32.913Z - **Finished:** 2026-09-13T23:31:26.178Z - **Download time:** 501 ms - **Static scan time:** 639 ms - **AI review time:** 52124 ms - **Total time:** 53265 ms The recorded confidence comes from the underlying analysis.

On macOS it can also replace and reload a persistent LaunchAgent. - **Trigger:** npm install runs postinstall. - **Impact:** Claude Code events can automatically invoke a version-pinned package command; the LaunchAgent can invoke it every five minutes. - **Evidence paths:** package.json, scripts/postinstall.cjs - **Review source:** ai\_review - **Reviewed:** 2026-09-13T23:31:26.178Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Install-time AI-agent hook injection and LaunchAgent persistence. - **Attack narrative:** The manifest invokes scripts/postinstall.cjs during installation. That script edits an existing Claude Code settings file to add SessionEnd and Stop hooks that run npx --yes ccclub@0.9.5 sync --silent. On macOS, when an existing dev.ccclub.sync LaunchAgent is present, it replaces the plist and reloads it; the generated agent runs the same command every 300 seconds. These changes occur without an explicit setup command from the user. - **Rationale:** This is an unconsented postinstall mutation of a foreign AI-agent control surface, with persistent automatic command execution. The existence checks limit targets but do not remove the install-time control-surface takeover. - **Files touched:** ~/.claude/settings.json, ~/Library/LaunchAgents/dev.ccclub.sync.plist ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The manifest automatically runs the postinstall script., Postinstall rewrites Claude Code SessionEnd and Stop hooks to run a version-pinned ccclub command., On macOS it rewrites and reloads an existing LaunchAgent that runs ccclub every five minutes. - **Evidence against:** Hook changes require an existing Claude settings file, and LaunchAgent changes require an existing plist., The manifest has no runtime dependency on ccclub itself. ## Affected versions and remediation This report applies to ccclub@0.9.5. - Avoid installing ccclub@0.9.5. 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.
