Foreign Hermes profiles, credentials, MCP configuration, skills, hooks, and sessions become active through ~/.overmind/hermes. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 3.9.0 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. On npm postinstall, the package rewires the pre-existing Hermes agent home to package-controlled storage. It preserves a backup but changes the active AI-agent configuration and imports credentials and skills without user confirmation. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-07-21T10:33:36.940Z - **Finished:** 2026-07-21T10:34:11.940Z - **Download time:** 508 ms - **Static scan time:** 1113 ms - **AI review time:** 33378 ms - **Total time:** 35000 ms ## Security analysis ### Published attack-surface review - **Summary:** On npm postinstall, the package rewires the pre-existing Hermes agent home to package-controlled storage. It preserves a backup but changes the active AI-agent configuration and imports credentials and skills without user confirmation. - **Trigger:** npm install when Docker is available - **Impact:** Foreign Hermes profiles, credentials, MCP configuration, skills, hooks, and sessions become active through ~/.overmind/hermes. - **Evidence paths:** package.json, scripts/postinstall.mjs - **Review source:** ai\_review - **Reviewed:** 2026-07-21T10:34:11.940Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall migration and symlink takeover of ~/.hermes - **Attack narrative:** The install hook executes without an explicit setup command. When Docker is present, it copies selected files and directories from the existing ~/.hermes agent home—including auth.json, .env, .mcp.json, skills, hooks, and sessions—into ~/.overmind/hermes, renames the original directory, and replaces ~/.hermes with a symlink to the package-controlled location. This is unconsented install-time mutation of a foreign AI-agent control surface. - **Rationale:** The package contains a concrete install-time takeover of an existing Hermes control surface, rather than merely an explicit user-invoked setup flow. That meets the blocking policy even though direct exfiltration was not found. - **Files touched:** package.json, scripts/postinstall.mjs - **Network endpoints:** https://raw.githubusercontent.com/DeamonDev888/overmind-mcp/main/.env.example, https://raw.githubusercontent.com/DeamonDev888/overmind-mcp/main/.mcp.json.example ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs scripts/postinstall.mjs automatically on install., scripts/postinstall.mjs unconditionally calls alignHermesHome() after Docker detection., alignHermesHome copies ~/.hermes auth/config/skills/sessions, renames the original directory, then symlinks ~/.hermes to ~/.overmind/hermes., postinstall fetches mutable configuration from raw.githubusercontent.com and installs another global npm package. - **Evidence against:** No source evidence that harvested Hermes data is sent to an external endpoint., Most runtime network calls are configured LLM or localhost service operations. ## Public findings ### 1.
