Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The package can persist a login-time listener and expose a remotely reachable terminal workflow. These capabilities require explicit CLI commands; no install-time trigger was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 84.0% - **Started:** 2026-09-14T10:54:44.894Z - **Finished:** 2026-09-14T10:56:01.883Z - **Download time:** 1272 ms - **Static scan time:** 4347 ms - **AI review time:** 71368 ms - **Total time:** 76989 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** The package can persist a login-time listener and expose a remotely reachable terminal workflow. These capabilities require explicit CLI commands; no install-time trigger was found. - **Trigger:** Running waterbrother listen install or waterbrother companion. - **Impact:** A user who enables these features can leave a persistent process and remote command surface available. - **Evidence paths:** src/cli.js, src/listen-agent.js, src/tools.js - **Review source:** ai\_review - **Reviewed:** 2026-09-14T10:56:01.883Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** LaunchAgent persistence plus a Tailscale-backed remote listener and agent shell tool. - **Rationale:** No unconsented install-time behavior or credential-exfiltration path was confirmed. The package nevertheless combines explicit persistence, remote listener setup, and shell execution, which warrants a warning for dangerous capability. - **Files touched:** ~/Library/LaunchAgents/app.waterbrother.listen.plist, ~/.waterbrother/companion.json - **Network endpoints:** https://api.waterbrother.app ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** An explicit listen install command creates a persistent macOS LaunchAgent that starts the package listener at login., The companion command sends the host name and requested listening port to the Waterbrother API, then maintains a remote listener., The agent exposes a general shell-execution tool; its safety depends on runtime approval settings rather than package-install isolation. - **Evidence against:** package.json has no preinstall, install, or postinstall lifecycle hook., The persistence path is reached only by an explicit listen install command., The companion network activity is reachable only through the explicit companion command and uses a stated package service. ## Affected versions and remediation This report applies to @tritard/waterbrother@0.17.11. - Review the evidence and your use of @tritard/waterbrother@0.17.11 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
