Code Relax Windows, macOS and Linux workstation service

AI Security Review

scanned 6d ago · by lpm-firewall-ai

Source inspection found a global-install setup flow and package-aligned workstation functionality, but no concrete attack behavior. The scanner’s similarity and structural hints do not establish maliciousness on their own.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

A global npm install invokes the package’s postinstall script.

Impact

The inspected behavior installs and starts the package’s workstation service. No concrete malicious effect was established.

Mechanism

The script prepares the package’s native component and runs its setup and health-check commands; the inspected account client connects to its configured service and subscribes to configured topics.

AI rationale

Decision evidence

public snapshot

AI called this Clean at 91.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

package.json runs a postinstall script that points to this package’s own installer.
The installer proceeds only when invoked directly during a global install, then runs this package’s setup and health-check commands.
The account client connects and subscribes to configured message topics; the inspected request path uses the account’s matching identity.
The inspected runtime and platform code handles local project operations, package-owned skill files, process startup, credential storage, and private network details.
The Windows desktop helper requests UAC elevation for its package-provided helper.
The bundled minified file begins as a UMD module export; its similarity hint alone does not establish malicious behavior.

Evidence against

The postinstall can set up a persistent workstation service during a global install, consistent with the package’s workstation-service function.
The inspected Windows helper uses an explicit UAC prompt for installation or removal.
