A user-invoked installer deploys an auto-loaded Hermes extension. Its pre-LLM lifecycle hook can perform a bounded automatic npm update on an interactive first turn; no install-time npm hook is present. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 88.0% - **Started:** 2026-08-12T02:31:48.352Z - **Finished:** 2026-08-12T02:32:50.343Z - **Download time:** 513 ms - **Static scan time:** 699 ms - **AI review time:** 60777 ms - **Total time:** 61991 ms ## Security analysis ### Published attack-surface review - **Summary:** A user-invoked installer deploys an auto-loaded Hermes extension. Its pre-LLM lifecycle hook can perform a bounded automatic npm update on an interactive first turn; no install-time npm hook is present. - **Trigger:** \`lithermes install --yes\`, followed by an interactive Hermes session's first LLM turn. - **Impact:** Modifies the configured Hermes profile and can replace its installed Lithermes payload; no credential exfiltration or destructive chain was confirmed. - **Evidence paths:** package.json, src/lib/install.js, assets/lithermes-plugin/plugin.yaml, assets/lithermes-plugin/auto\_update.py, src/lib/updateNotifier.js - **Review source:** ai\_review - **Reviewed:** 2026-08-12T02:32:50.343Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Hermes plugin deployment, lifecycle hooks, and guarded npm self-update. - **Rationale:** Not malicious under the stated boundary: mutation is user-command gated and there is no npm preinstall/install/postinstall behavior. Warn because a loaded agent extension can self-update from npm during an interactive pre-LLM lifecycle event. - **Files touched:** assets/lithermes-plugin, ~/.hermes/plugins/lithermes, ~/.hermes/config.yaml, ~/.hermes/lithermes/auto-update-receipt.json - **Network endpoints:** https://registry.npmjs.org/lithermes-ai/latest ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** Explicit \`install --yes\` copies a bundled Hermes plugin and enables it in the host configuration., The bundled plugin auto-loads and registers \`pre\_llm\_call\` plus other Hermes lifecycle hooks., On the first interactive LLM turn, the plugin can fetch npm registry metadata and invoke \`npx\` for an exact newer package version. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., Installation refuses host mutation unless the user supplies \`--yes\`., Update subprocess environment is allowlisted and omits token-bearing npm environment variables. ## Public findings ### 1.
