If herdr loads that plugin, it can start a detached local tmux clipboard bridge. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 88.0% - **Started:** 2026-08-16T10:53:39.677Z - **Finished:** 2026-08-16T10:54:46.087Z - **Download time:** 797 ms - **Static scan time:** 2971 ms - **AI review time:** 62640 ms - **Total time:** 66410 ms ## Security analysis ### Published attack-surface review - **Summary:** npm install writes a package-supplied herdr configuration and copies a herdr plugin. If herdr loads that plugin, it can start a detached local tmux clipboard bridge. - **Trigger:** npm install, followed by herdr loading the copied plugin - **Impact:** Unconsented lifecycle setup in an external herdr control surface; no confirmed exfiltration or remote payload execution. - **Evidence paths:** package.json, scripts/copy-plugins.js, config.toml.example, .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:** 2026-08-16T10:54:46.087Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** install-time first-party plugin and configuration deployment - **Rationale:** The package performs install-time mutation of an external extension/configuration surface and installs a background-capable plugin. Its visible payload is local clipboard bridging, not a concrete malicious chain. - **Files touched:** ~/.pi-harness-runtime/cookies, ~/.config/herdr/config.toml, ~/.config/herdr/plugins/herdr-clipboard, .pi/plugins/herdr-clipboard/start-bridge.sh, ~/.herdr-clipboard ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** postinstall creates runtime cookie storage and mutates ~/.config/herdr., Installer copies every bundled .pi plugin into herdr's plugin directory., Bundled plugin declares a detached startup command., Startup script creates a persistent tmux clipboard bridge. - **Evidence against:** Install script has no network operation or credential exfiltration., Bundled watcher only moves a local bridge file into a tmux buffer., Cron/systemd adapters are library code with no detected runtime call site. ## Public findings ### 1.
