Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. Source confirms an opt-in automatic self-update path and first-party plugin registry mutation. The manifest lacks install-time lifecycle hooks and inspection found no concrete exfiltration or malicious payload chain. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 85.0% - **Started:** 2026-08-24T04:36:47.014Z - **Finished:** 2026-08-24T04:38:08.560Z - **Download time:** 1032 ms - **Static scan time:** 17272 ms - **AI review time:** 63240 ms - **Total time:** 81546 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:** A Claude session-start hook can check for and, after prior opt-in, silently apply an OMC update. The update refreshes this package's plugin cache/registry and globally installs the same package. - **Trigger:** Claude session start after the user has enabled silentAutoUpdate, or an explicit update command - **Impact:** Remote package updates can change the installed OMC extension; no foreign/broad control-surface overwrite was confirmed. - **Evidence paths:** package.json, dist/hooks/bridge.js, dist/features/auto-update.js, dist/hooks/team-dispatch-hook.js, dist/tools/ast-tools.js - **Review source:** ai\_review - **Reviewed:** 2026-08-24T04:38:08.560Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** opt-in self-update and first-party Claude plugin cache synchronization - **Rationale:** Source confirms an opt-in automatic self-update path and first-party plugin registry mutation. The manifest lacks install-time lifecycle hooks and inspection found no concrete exfiltration or malicious payload chain. - **Files touched:** dist/hooks/bridge.js, dist/features/auto-update.js, ~/.claude/plugins/installed\_plugins.json, ~/.claude/plugins/cache/omc/oh-my-claudecode - **Network endpoints:** https://api.github.com/repos/Yeachan-Heo/oh-my-claudecode, https://raw.githubusercontent.com/Yeachan-Heo/oh-my-claudecode ### Review decision - **Verdict:** Suspicious - **Confidence:** 85.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** Session-start hook invokes silent-update initialization., Opt-in silent update fetches GitHub release data and runs a global npm install., Update code rewrites only its own OMC plugin registry entries and cache. - **Evidence against:** package.json has no preinstall/install/postinstall hook., Silent updates default disabled when config is absent or invalid., No credential harvesting or exfiltration beyond GitHub update requests was found. ## Affected versions and remediation This report applies to oh-my-claude-sisyphus@5.0.0. - Review the evidence and your use of oh-my-claude-sisyphus@5.0.0 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
