An unrelated agent control surface is changed without user action, and the deployed background process can manipulate clipboard-derived terminal input. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 1.1.50 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. LPM flags this version as an AI-agent control-surface risk. Installation silently modifies Herdr's global configuration area and deploys an automatically started plugin. The plugin establishes a persistent tmux clipboard bridge capable of injecting watched content into a tmux pane. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-14T03:04:55.991Z - **Finished:** 2026-09-14T03:05:57.951Z - **Download time:** 1273 ms - **Static scan time:** 2388 ms - **AI review time:** 58297 ms - **Total time:** 61960 ms The recorded confidence comes from the underlying analysis.

The plugin establishes a persistent tmux clipboard bridge capable of injecting watched content into a tmux pane. - **Trigger:** npm installation, followed by a Herdr startup - **Impact:** An unrelated agent control surface is changed without user action, and the deployed background process can manipulate clipboard-derived terminal input. - **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:** 2026-09-14T03:05:57.951Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall deployment of an auto-starting global agent plugin - **Attack narrative:** Installing the package automatically creates and populates Herdr's global configuration and plugin directories. It copies a bundled clipboard plugin without an explicit setup command. When Herdr starts, that plugin launches a detached tmux session that continuously watches a home-directory file and pastes changed content into tmux. This forms an unconsented lifecycle path from npm installation to persistent modification of another agent environment and terminal-input manipulation. - **Rationale:** The postinstall hook mutates a foreign global agent control surface and installs an auto-starting background plugin. This is concrete unconsented install-hook abuse, even though no install-time network exfiltration was found. - **Files touched:** ~/.pi-harness-runtime/cookies, ~/.config/herdr/config.toml, ~/.config/herdr/plugins/herdr-clipboard, ~/.herdr-clipboard/bridge.pid, ~/.herdr-clipboard/copy-buffer, ~/.herdr-clipboard/.last-hash ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The automatic postinstall creates home-directory state, copies a config file into Herdr, and runs a plugin copier., The copier installs every bundled plugin into the global Herdr plugin directory., The installed plugin is configured to start a detached background bridge whenever Herdr starts., That bridge creates a tmux session and repeatedly transfers watched content into the active tmux paste buffer. - **Evidence against:** No install-time network request or self-dependency was found., The GitHub clipboard sync path requires explicit credential setup and a user shortcut. ## Affected versions and remediation This report applies to pi-harness-runtime@1.1.50. - Avoid installing pi-harness-runtime@1.1.50. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
