The package gains automatic execution in Claude Code and can cause background sync behavior without an explicit setup command. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.9.6 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. npm postinstall mutates an existing Claude Code settings file to add automatic SessionEnd and Stop hooks. Those hooks execute a pinned npx sync command; an existing macOS LaunchAgent may also be repinned and reloaded. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-09-04T16:09:31.782Z - **Finished:** 2026-09-04T16:10:28.505Z - **Download time:** 255 ms - **Static scan time:** 1023 ms - **AI review time:** 55444 ms - **Total time:** 56723 ms ## Security analysis ### Published attack-surface review - **Summary:** npm postinstall mutates an existing Claude Code settings file to add automatic SessionEnd and Stop hooks. Those hooks execute a pinned npx sync command; an existing macOS LaunchAgent may also be repinned and reloaded. - **Trigger:** Installing the package where ~/.claude/settings.json exists; later Claude session events trigger the hook. - **Impact:** The package gains automatic execution in Claude Code and can cause background sync behavior without an explicit setup command. - **Evidence paths:** package.json, scripts/postinstall.cjs - **Review source:** ai\_review - **Reviewed:** 2026-09-04T16:10:28.505Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Install-time foreign AI-agent hook injection and persistent version-pinned npx execution. - **Attack narrative:** The package declares postinstall, which runs scripts/postinstall.cjs during npm installation. When Claude Code settings already exist, the script removes prior ccclub hooks and adds SessionEnd and Stop hooks that execute \`npx --yes ccclub@0.9.6 sync --silent\`. This is an unconsented mutation of a foreign AI-agent control surface. On macOS, it also updates and reloads an existing five-minute LaunchAgent pointing to the same npx command. - **Rationale:** The package automatically injects persistent Claude Code hooks during installation, rather than limiting that agent integration to an explicit user command. This meets the install-time foreign AI-agent control-surface mutation block policy. - **Files touched:** ~/.claude/settings.json, ~/Library/LaunchAgents/dev.ccclub.sync.plist, ~/.ccclub/sync.log - **Network endpoints:** https://ccclub.dev ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The install lifecycle runs a package script automatically after npm installation., That script rewrites Claude Code SessionEnd and Stop hooks to run a version-pinned npx command., It writes the modified foreign Claude settings file without an explicit user command., On macOS it can also reload an existing LaunchAgent that runs the same silent sync every five minutes. - **Evidence against:** The hook rewrite is conditional on an existing Claude settings file., Silent sync skips uploads when no ccclub configuration exists., The manifest has no runtime dependency on ccclub itself. ## Public findings ### 1.
