## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 20 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:** 1.1.8
- **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 package performs substantial automatic install-time mutation and persistence, including installation of an unrelated global package. The code does not establish the stronger malicious chain required for a publish block.

## Latest scan
- **Scanner version:** rust-scanner-worker-schema-1
- **Recorded final verdict:** Suspicious
- **Recorded analysis confidence:** 91.0%
- **Started:** 2026-08-29T14:36:07.519Z
- **Finished:** 2026-08-29T14:37:46.780Z
- **Download time:** 501 ms
- **Static scan time:** 2817 ms
- **AI review time:** 95942 ms
- **Total time:** 99261 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:** Installing the package automatically changes user configuration, installs another global package, and attempts to enable a persistent service. No confirmed credential theft or data exfiltration was found in the inspected installer.

- **Trigger:** npm installation runs the postinstall hook.

- **Impact:** It can alter shell startup files or Windows user PATH and create a persistent process without an explicit setup command.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-29T14:37:46.780Z

### AI review details

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

- **Mechanism:** Automatic profile mutation, global package installation, and service setup.

- **Rationale:** The package performs substantial automatic install-time mutation and persistence, including installation of an unrelated global package. The code does not establish the stronger malicious chain required for a publish block.

- **Files touched:** ~/.zshrc, ~/.bash\_profile, ~/.profile, Windows user Path, ~/.xyt-agent/logs/xyt-client.log, ~/.xyt-agent/xyt-client.pid

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

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 91.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Low

- **Evidence for warning:** The install hook automatically changes user shell or Windows PATH settings., The install hook invokes its own service-install command, creating a watchdog-backed background restart mechanism., The hook installs the separate global tokscale package automatically., Published runtime files are deliberately obfuscated, limiting auditability.

- **Evidence against:** No runtime dependency on xyt-agentos itself is declared., The inspected install hook contains no credential collection or outbound data upload., The watchdog only restarts the package command and reads its own log and PID paths.

## Affected versions and remediation

This report applies to xyt-agentos@1.1.8.

- Review the evidence and your use of xyt-agentos@1.1.8 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.
