xyt-agentos@1.1.8
XYT AgentOS — Workent 龙虾桌面 Agent 客户端（xyt-client）
AI Security Review
scanned 2mo ago · by lpm-firewall-aiThe 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.
Static reason
High-risk behavior combination matched malicious policy.
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.
Mechanism
Automatic profile mutation, global package installation, and service setup.
AI 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.

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with low false-positive risk.
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.
