## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 24 finding(s) warrant review before installing.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Matched warn-list
- **Public report status:** Published
- **Threat category:** Install Hook Abuse
- **Selected version:** 1.1.9
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. 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 install hook unconsentedly changes user PATH, installs crontab persistence through an obfuscated binary, and globally installs tokscale from a mirror, which is real install-hook risk. It does not show a hidden steal-and-send chain or a direct install-time rewrite of foreign agent config, so the package is a dangerous installer rather than confirmed malware.

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:** Installing the package rewrites shell or Windows PATH, starts a service installer that edits crontab, and globally installs tokscale from a third-party npm mirror. The obfuscated client also targets foreign agent skill folders and a vendor websocket, but those writes are not shown on the install path itself.

- **Trigger:** npm install runs the postinstall script, and later xyt-client service or start commands run the obfuscated client.

- **Impact:** A normal install can persist the client, change the user PATH, and pull another global package from registry.npmmirror.com. Runtime use can read or write other agents' skill directories and upload client telemetry to the vendor service.

- **Evidence paths:** package.json, scripts/postinstall.mjs, dist/cli.js, dist/index.js, dist/socket-server.js, scripts/agentos-watchdog.sh

- **Review source:** ai\_review

- **Reviewed:** 2026-09-24T01:11:05.341Z

### AI review details

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

- **Mechanism:** postinstall appends PATH entries, launches powershell with ExecutionPolicy Bypass on Windows, executes xyt-client service install, and runs npm install -g tokscale. The bundled CLI contains a crontab update, and the bundles resolve .claude, .cursor, and .codex skill paths plus an api.minimaxi.com-style host and wss endpoint.

- **Rationale:** The install hook unconsentedly changes user PATH, installs crontab persistence through an obfuscated binary, and globally installs tokscale from a mirror, which is real install-hook risk. It does not show a hidden steal-and-send chain or a direct install-time rewrite of foreign agent config, so the package is a dangerous installer rather than confirmed malware.

- **Files touched:** ~/.zshrc, ~/.bash\_profile, ~/.profile, crontab, .claude/skills, .cursor/skills, .codex

- **Network endpoints:** https://registry.npmmirror.com

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 78.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Dangerous Capability

- **False-positive risk:** Medium

- **Evidence for warning:** npm install runs scripts/postinstall.mjs automatically., That hook appends a PATH export to the user .zshrc, .bash\_profile, and .profile when those files exist., On Windows it writes the user Path variable through powershell with ExecutionPolicy Bypass., If the global xyt-client binary exists, postinstall runs service install, and the obfuscated CLI edits the user crontab to keep the client alive., Postinstall also runs npm install -g tokscale, first against registry.npmmirror.com., Obfuscated dist bundles resolve .claude, .cursor, and .codex skill directories and open a product websocket.

- **Evidence against:** The install script prints the PATH and watchdog changes instead of hiding them., Claude, Cursor, and Codex path handling sits in the runtime client, not in a direct postinstall write., Visible hosts are the product API fragments and the npm mirror, and the package does not depend on itself.
