A user-invoked installer deploys an auto-loaded Hermes agent extension. On eligible interactive turns, its hook can retrieve and install a newer package version. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 93.0% - **Started:** 2026-08-14T05:26:29.793Z - **Finished:** 2026-08-14T05:27:29.925Z - **Download time:** 511 ms - **Static scan time:** 620 ms - **AI review time:** 59000 ms - **Total time:** 60132 ms ## Security analysis ### Published attack-surface review - **Summary:** A user-invoked installer deploys an auto-loaded Hermes agent extension. On eligible interactive turns, its hook can retrieve and install a newer package version. - **Trigger:** User runs lithermes install --yes; later first interactive Hermes turn. - **Impact:** Can replace the installed agent extension and affect Hermes hook behavior; source also supports guarded host compatibility patches. - **Evidence paths:** src/lib/install.js, src/lib/patch.js, assets/lithermes-plugin/plugin.yaml, assets/lithermes-plugin/auto\_update.py - **Review source:** ai\_review - **Reviewed:** 2026-08-14T05:27:29.925Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Auto-loaded hook performs registry-driven npx self-update and modifies its Hermes-owned plugin/config surface. - **Rationale:** This is not concrete malware, but it creates a guarded, persistent agent-extension update/control surface with optional host-source patching. Per policy, that warrants a warning rather than a block. - **Files touched:** src/lib/install.js, src/lib/patch.js, assets/lithermes-plugin/plugin.yaml, assets/lithermes-plugin/auto\_update.py - **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:** Medium - **Evidence for:** Auto-loaded Hermes plugin registers pre-LLM and tool/session hooks., Explicit install copies the bundled plugin and enables it in Hermes configuration., The installed hook checks npm registry then runs an exact-version npx update., Installer may patch detected Hermes runtime sources as part of setup. - **Evidence against:** No npm preinstall/install/postinstall lifecycle hook exists., Install refuses configuration mutation unless the user supplies --yes., Update path is limited to interactive first turns and sanitizes child environment., Observed network endpoint is the package-aligned npm registry; no credential exfiltration found. ## Public findings ### 1.
