The package is a user-invoked remote AI/terminal controller with explicit relay, PTY, SSH, and service-management features aligned with its description. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Clean - **Confidence:** 86.0% - **Started:** 2026-07-03T04:21:25.841Z - **Finished:** 2026-07-03T04:22:32.795Z - **Download time:** 502 ms - **Static scan time:** 939 ms - **AI review time:** 65512 ms - **Total time:** 66954 ms ## Security analysis ### Published attack-surface review - **Summary:** No confirmed malicious attack surface. The package is a user-invoked remote AI/terminal controller with explicit relay, PTY, SSH, and service-management features aligned with its description. - **Trigger:** User runs \`reins\` or \`reins service install\`. - **Impact:** Remote paired clients can send terminal input, manage SSH/local sessions, and run allowed AI CLI tools after pairing/auth. - **Evidence paths:** package.json, dist/cli.mjs - **Review source:** ai\_review - **Reviewed:** 2026-07-03T04:22:32.795Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** User-authorized remote terminal and AI-agent session bridge - **Rationale:** Static inspection shows powerful remote-control primitives, but they are documented, user-invoked package functionality with no lifecycle execution, hidden payload decode/execute, credential exfiltration, or automatic persistence. The scanner's persistence and shell findings map to explicit service/terminal features rather than malicious behavior. - **Files touched:** ~/.ai\_remote\_vibe\_agent/headless-store.json, ~/.ai\_remote\_vibe\_agent/session-token.txt, ~/.ai\_remote\_vibe\_agent/.env, ~/.ai\_remote\_vibe\_agent/logs, ~/.claude\_code\_agent/machines.json, ~/.claude\_code\_agent/keyring.key, ~/.config/systemd/user/reins.service, ~/Library/LaunchAgents/com.junyoung-kim.reins.plist, ~/.ai\_remote\_vibe\_agent/reins-service.cmd - **Network endpoints:** wss://relay.juny-api.kr/relay, wss://juny-api.kr/relay, https://arv.juny-api.kr ### Review decision - **Verdict:** Clean - **Confidence:** 86.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Medium - **Evidence for:** dist/cli.mjs can spawn local PTYs and allowed AI CLIs via node-pty/child\_process., dist/cli.mjs connects to relay URLs such as wss://relay.juny-api.kr/relay and wss://juny-api.kr/relay., dist/cli.mjs supports explicit service install via launchd/systemd/schtasks. - **Evidence against:** package.json has no install/postinstall lifecycle scripts; bin is user-invoked dist/cli.mjs., Remote terminal/AI-agent control is the advertised package purpose, not hidden behavior., Agent argv validation only allows claude, codex, or gemini executables., No eval/Function remote payload execution pattern found in inspected source., Persistence code is behind explicit \`reins service install\`, not automatic import/install-time execution. ## Public findings ### 1.
