A user-confirmed installer deploys and enables a persistent LitHermes plugin. That plugin auto-loads hooks and can fetch and install newer package versions during a qualifying interactive first turn. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 93.0% - **Started:** 2026-08-11T22:47:24.094Z - **Finished:** 2026-08-11T22:48:46.334Z - **Download time:** 754 ms - **Static scan time:** 917 ms - **AI review time:** 80567 ms - **Total time:** 82240 ms ## Security analysis ### Published attack-surface review - **Summary:** A user-confirmed installer deploys and enables a persistent LitHermes plugin. That plugin auto-loads hooks and can fetch and install newer package versions during a qualifying interactive first turn. - **Trigger:** User runs \`lithermes install --yes\`, then starts an interactive top-level Hermes session. - **Impact:** The package gains ongoing control over the installed Hermes plugin surface and can replace its own payload from npm. - **Evidence paths:** src/lib/install.js, assets/lithermes-plugin/plugin.yaml, assets/lithermes-plugin/core.py, assets/lithermes-plugin/auto\_update.py, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-11T22:48:46.334Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** First-party Hermes extension installation with guarded registry-driven self-update. - **Rationale:** No malicious install hook, credential harvesting, or exfiltration was found. The explicit installer plus automatic hook-driven self-update is a real first-party agent extension lifecycle risk requiring a warning. - **Files touched:** ~/.hermes/plugins/lithermes, ~/.hermes/config.yaml, ~/.hermes/lithermes/install-manifest.json - **Network endpoints:** https://registry.npmjs.org/lithermes-ai/latest ### Review decision - **Verdict:** Suspicious - **Confidence:** 93.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** Explicit \`install --yes\` replaces a Hermes plugin payload and enables it in Hermes configuration., Bundled plugin auto-loads with LLM and tool lifecycle hooks., On an interactive first LLM turn, the plugin invokes an automatic update bridge., The update bridge queries npm registry and runs an exact-version \`npx\` installer. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., Foreign Hermes changes require the user-invoked install command and \`--yes\`., Registry response/version handling and child environment are bounded and sanitized; no credential exfiltration found. ## Public findings ### 1.
