Unconsented modification of user-level Herdr configuration and plugin execution surface. - **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:** 1.1.5 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. On npm install, the package installs a plugin and configuration into the unrelated Herdr user control surface. That plugin declares detached startup and launches a persistent clipboard bridge. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 96.0% - **Started:** 2026-08-16T11:03:12.019Z - **Finished:** 2026-08-16T11:04:22.052Z - **Download time:** 1023 ms - **Static scan time:** 3191 ms - **AI review time:** 65817 ms - **Total time:** 70033 ms ## Security analysis ### Published attack-surface review - **Summary:** On npm install, the package installs a plugin and configuration into the unrelated Herdr user control surface. That plugin declares detached startup and launches a persistent clipboard bridge. - **Trigger:** npm postinstall, followed by Herdr plugin startup - **Impact:** Unconsented modification of user-level Herdr configuration and plugin execution surface. - **Evidence paths:** package.json, scripts/copy-plugins.js, .pi/plugins/herdr-clipboard/herdr-plugin.toml, .pi/plugins/herdr-clipboard/start-bridge.sh, .pi/plugins/herdr-clipboard/tmux-watch.sh - **Review source:** ai\_review - **Reviewed:** 2026-08-16T11:04:22.052Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic foreign agent-plugin installation with detached clipboard watcher - **Attack narrative:** Installing the package runs postinstall without a user command. It copies all bundled plugins into ~/.config/herdr/plugins and creates a Herdr configuration file. The bundled plugin is configured for detached startup; its script starts a persistent tmux watcher that processes clipboard-bridge content. This is an unconsented install-time mutation of a foreign user-level agent/plugin control surface. - **Rationale:** The automatic postinstall writes and activates a third-party Herdr plugin surface; this meets the install-control-surface block boundary. No lifecycle network exfiltration was found, but it is not required for this concrete control-surface mutation. - **Files touched:** ~/.pi-harness-runtime/cookies, ~/.config/herdr/config.toml, ~/.config/herdr/plugins/herdr-clipboard, ~/.herdr-clipboard/bridge.pid, ~/.herdr-clipboard/copy-buffer ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** npm postinstall creates home-state and mutates ~/.config/herdr., Install hook recursively copies bundled Herdr plugins into the user plugin directory., Bundled plugin declares a detached startup command., Startup script launches a persistent tmux watcher that consumes clipboard-bridge content. - **Evidence against:** The lifecycle hook contains no network request., The copied config is only created when absent. ## Public findings ### 1.
