On a later Herdr startup, the copied plugin can launch a detached persistent tmux clipboard process. - **Trigger:** npm installation followed by Herdr loading its plugin directory - **Impact:** Unconsented modification of a separate agent control surface and persistent background clipboard handling. - **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:** 2026-08-31T07:51:23.996Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic foreign agent-plugin installation with detached background execution - **Attack narrative:** The postinstall hook creates global directories, copies bundled content into Herdr's plugin directory, and creates a global Herdr configuration if absent. The copied plugin declares a detached startup command. When Herdr loads that directory, the command starts a tmux session whose watcher continuously reads a clipboard bridge file and injects its contents into tmux. This is an unconsented install-time modification of a separate agent platform that establishes persistent background behavior. - **Rationale:** The package uses postinstall to mutate a foreign global agent plugin and configuration surface, then installs a plugin that starts detached background execution. This meets the install-hook abuse boundary even though the inspected clipboard code has no network exfiltration. - **Files touched:** ~/.pi-harness-runtime/cookies, ~/.config/herdr/plugins, ~/.config/herdr/config.toml, ~/.herdr-clipboard, ~/.herdr-clipboard/bridge.pid ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The automatic postinstall hook copies a bundled plugin into the separate Herdr plugin directory and creates a Herdr configuration file., The installer recursively copies every bundled plugin without asking the user., The installed Herdr plugin declares a detached startup command., That startup command creates a background tmux session running an endless clipboard watcher. - **Evidence against:** No runtime dependency on this package name was found., The inspected clipboard scripts contain no network request or secret-exfiltration logic. ## Public findings ### 1.
