It also refreshes an existing macOS LaunchAgent that runs the package every five minutes. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-09T05:47:29.869Z - **Finished:** 2026-08-09T05:48:19.380Z - **Download time:** 250 ms - **Static scan time:** 293 ms - **AI review time:** 48967 ms - **Total time:** 49511 ms ## Security analysis ### Published attack-surface review - **Summary:** npm postinstall silently mutates Claude Code's settings to add automatic command hooks. It also refreshes an existing macOS LaunchAgent that runs the package every five minutes. - **Trigger:** npm install - **Impact:** Automatically executes version-pinned package code after Claude sessions and via launchd. - **Evidence paths:** package.json, scripts/postinstall.cjs, dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-09T05:48:19.380Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** install-time foreign AI-agent hook mutation and persistence refresh - **Attack narrative:** Installing the package executes postinstall, which rewrites Claude Code SessionEnd and Stop hooks to invoke npx --yes ccclub@0.6.16 sync --silent without an explicit setup command. On macOS, it also reloads an existing LaunchAgent that invokes the same command every five minutes. The runtime sync path maintains these controls and uploads collected usage data to the configured ccclub API. - **Rationale:** This is concrete, unconsented postinstall mutation of a foreign AI-agent control surface, with persistent automatic execution. The conditional existence check does not make the configuration change user-consented. - **Files touched:** package.json, scripts/postinstall.cjs, dist/index.js, ~/.claude/settings.json, ~/Library/LaunchAgents/dev.ccclub.sync.plist, ~/.ccclub/sync.log - **Network endpoints:** https://ccclub.dev, https://api.anthropic.com/api/oauth/usage ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs scripts/postinstall.cjs on npm install., scripts/postinstall.cjs rewrites ~/.claude/settings.json hooks., The added SessionEnd/Stop hooks run npx --yes ccclub@0.6.16 sync --silent., On macOS it repins and reloads dev.ccclub.sync LaunchAgent., dist/index.js sync re-installs hooks/heartbeat and uploads collected usage. - **Evidence against:** Postinstall limits hook mutation to systems with an existing ~/.claude/settings.json., No hidden payload, eval, or arbitrary remote-code loader was found. ## Public findings ### 1.
