Paired relay/mobile clients can receive terminal output and send terminal input. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 88.0% - **Started:** 2026-08-05T09:12:15.710Z - **Finished:** 2026-08-05T09:12:50.753Z - **Download time:** 756 ms - **Static scan time:** 1094 ms - **AI review time:** 33192 ms - **Total time:** 35043 ms ## Security analysis ### Published attack-surface review - **Summary:** Running the CLI starts a remote terminal host and connects it to a relay. Paired relay/mobile clients can receive terminal output and send terminal input. - **Trigger:** User runs reins, then pairs a mobile client or enables its service. - **Impact:** A compromised or untrusted relay/pairing path could expose terminal data or permit command input. - **Evidence paths:** package.json, dist/cli.mjs, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-05T09:12:50.753Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** WebSocket relay-backed PTY and SSH session control - **Rationale:** This is not malicious install-time behavior, but its intentional remote terminal/AI-agent control and data forwarding create a real dangerous capability and relay-trust risk. - **Files touched:** dist/cli.mjs, package.json, README.md - **Network endpoints:** wss://relay.juny-api.kr/relay, https://registry.npmjs.org/@junyoung-kim%2Freins/latest, https://arv.juny-api.kr/updates ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for:** dist/cli.mjs connects terminal host sessions to the default relay., dist/cli.mjs forwards PTY data and accepts remote session messages., dist/cli.mjs can read SSH keys and Claude session transcripts., dist/cli.mjs registers persistent user services only via explicit commands/UI. - **Evidence against:** package.json has no preinstall/install/postinstall hooks., README.md and CLI describe the remote-terminal relay behavior., No eval, decoded remote payload execution, or hidden lifecycle trigger found., Service installation is user-invoked and writes package-owned user services. ## Public findings ### 1.
