AI Security Review
scanned 8d ago · by lpm-firewall-aiThe postinstall hook automatically registers and starts a package-owned daemon with login persistence. The reviewed source supports a lifecycle-risk warning, but does not establish broader control-surface abuse or another concrete attack.
Static reason
One or more suspicious static signals were detected.
Trigger
Installing the package outside CI, without the repair-only flag.
Impact
The daemon may keep running and start again at later logins without a separate daemon launch command.
Mechanism
The installer registers the package daemon with the platform service manager and enables or starts it.
AI rationale
The postinstall hook automatically registers and starts a package-owned daemon with login persistence. The reviewed source supports a lifecycle-risk warning, but does not establish broader control-surface abuse or another concrete attack.
Evidence

Decision evidence
public snapshotAI called this Suspicious at 86.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- package.json runs install.cjs automatically during postinstall.
- The installer calls registerDaemons() during that lifecycle, after repairing command targets.
- The default path creates a per-user service that starts the package daemon and enables it at login.
- Registration is skipped when CI is set; the install-only repair flag is another guard.
Evidence against
- The startup registration is for this package’s own daemon, rather than a broad or foreign agent control surface.
- The installer can remove its own registration and service files.
