## Security analysis

### Published attack-surface review

- **Summary:** Installation mutates interactive shell profiles and attempts to install an always-on service guard. The bundled watchdog restarts the client when it stops.

- **Trigger:** npm postinstall, especially global installation where xyt-client is available

- **Impact:** Changes user startup configuration and establishes recurring execution of the package client.

- **Evidence paths:** package.json, scripts/postinstall.mjs, scripts/agentos-watchdog.sh

- **Review source:** ai\_review

- **Reviewed:** 2026-08-23T08:31:23.579Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** unconsented shell-profile modification and service persistence

- **Attack narrative:** The package executes a postinstall hook that appends its PATH entry to shell startup files. When the global binary is present, it silently runs its service-install command and states that it configures launchd or cron. Its supplied watchdog then restarts the client when its log or PID check indicates it is absent, creating unconsented persistence from installation.

- **Rationale:** Source inspection confirms install-time mutation of user shell configuration and automatic persistence, not merely static hints. This is concrete unconsented behavior with system-wide startup impact.

- **Files touched:** scripts/postinstall.mjs, scripts/agentos-watchdog.sh, .zshrc, .bash\_profile, .profile, .xyt-agent/logs/xyt-client.log, .xyt-agent/xyt-client.pid

### Review decision

- **Verdict:** Malicious

- **Confidence:** 96.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** postinstall runs automatically on npm installation., It appends a PATH export to user shell profiles without a user command., It invokes \`xyt-client service install\` during installation., The install path reports launchd/cron process-guard setup., Bundled watchdog restarts \`xyt-client\` when it is absent.

- **Evidence against:** No concrete external network endpoint was confirmed from inspected unobfuscated source., The persistence targets the package's own \`xyt-client\` process.
