The auto-loaded Hermes plugin can fetch and install a newer lithermes-ai release during the first interactive model turn. No credential exfiltration or npm install lifecycle hook was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 90.0% - **Started:** 2026-09-01T00:32:15.623Z - **Finished:** 2026-09-01T00:34:50.536Z - **Download time:** 1023 ms - **Static scan time:** 1141 ms - **AI review time:** 152747 ms - **Total time:** 154913 ms ## Security analysis ### Published attack-surface review - **Summary:** The auto-loaded Hermes plugin can fetch and install a newer lithermes-ai release during the first interactive model turn. No credential exfiltration or npm install lifecycle hook was found. - **Trigger:** The first interactive top-level Hermes pre-LLM turn after the plugin is installed. - **Impact:** A future registry release can replace the installed agent extension and modify its Hermes configuration without a new explicit install command. - **Evidence paths:** assets/lithermes-plugin/plugin.yaml, assets/lithermes-plugin/auto\_update.py, src/lib/updateNotifier.js - **Review source:** ai\_review - **Reviewed:** 2026-09-01T00:34:50.536Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Registry version check followed by an npx-based self-update of the Hermes plugin. - **Rationale:** This is a concrete guarded agent-extension lifecycle risk rather than confirmed malware. The package lacks an install-time lifecycle hook and no source evidence shows secret harvesting, destructive activity, or unrelated exfiltration. - **Files touched:** .hermes/plugins/lithermes, .hermes/config.yaml, .hermes/lithermes/auto-update - **Network endpoints:** https://registry.npmjs.org/lithermes-ai/latest ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** The installed plugin auto-loads and registers a pre-LLM hook., That hook checks the npm registry and silently launches an exact newer package release through npx., The Node transaction then installs the fetched release into the Hermes profile with automatic confirmation., This is a guarded first-party agent-extension update path, but it still changes agent code during normal interactive use. - **Evidence against:** The npm manifest has no install, preinstall, or postinstall hook., Initial installation refuses configuration changes without an explicit --yes flag., The updater runs only on the first interactive top-level turn and supports opt-out environment variables., The child installer receives a reduced environment that excludes token-bearing variables. ## Public findings ### 1.
