Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Installing the package mutates an existing Claude Code control file to run ccclub automatically at session end and stop. It also refreshes an existing macOS background agent that repeatedly runs ccclub through npx. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-19T16:52:08.792Z - **Finished:** 2026-09-19T16:53:39.008Z - **Download time:** 510 ms - **Static scan time:** 625 ms - **AI review time:** 89080 ms - **Total time:** 90216 ms The recorded confidence comes from the underlying analysis.

It also refreshes an existing macOS background agent that repeatedly runs ccclub through npx. - **Trigger:** npm installation on a machine with Claude Code settings or the package's existing macOS LaunchAgent. - **Impact:** Future agent events and login/background execution can fetch and run the specified ccclub release without a separate user command. - **Evidence paths:** package.json, scripts/postinstall.cjs - **Review source:** ai\_review - **Reviewed:** 2026-09-19T16:53:39.008Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Install-time AI-agent hook mutation and background command persistence. - **Attack narrative:** The postinstall lifecycle runs automatically. If Claude Code settings exist, it inserts ccclub commands for SessionEnd and Stop; those commands use npx with a package version. On macOS, if the ccclub LaunchAgent exists, postinstall replaces and reloads it so it runs npx ccclub sync every 300 seconds and at load. This is unconsented install-time mutation of an AI-agent control surface plus persistent execution. - **Rationale:** The package establishes automatic hooks during postinstall in a foreign AI-agent settings file and retains a background npx execution path. These are concrete install-hook and persistence behaviors, not merely an explicit user-command setup. - **Files touched:** package.json, scripts/postinstall.cjs, ~/.claude/settings.json, ~/Library/LaunchAgents/dev.ccclub.sync.plist - **Network endpoints:** registry.npmjs.org ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The manifest automatically runs a postinstall script., That script writes command hooks into the existing Claude Code settings file., The installed hooks invoke a version-pinned ccclub package through npx when sessions end or stop., On macOS, the same install hook refreshes a LaunchAgent that runs the package every five minutes and at login. - **Evidence against:** The postinstall script limits hook replacement to commands it identifies as ccclub-managed., The Cursor token is sent only to Cursor's fixed API host. ## Affected versions and remediation This report applies to ccclub@0.9.3. - Avoid installing ccclub@0.9.3. 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.
