AI Security Review

scanned 13d ago · by lpm-firewall-ai

Source inspection supports a clean verdict: the install hook is a package-owned runtime patch, and the flagged runtime behaviors align with the CLI's own setup and update functions. No concrete attack behavior was found in the inspected source.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

Package installation triggers the postinstall patch script; agent setup, network requests, and updating occur during CLI use.

Impact

No concrete credential theft, unauthorized control-surface mutation, or other attack was established.

Mechanism

The inspected code applies patches to the Pi runtime, configures package-named extensions and credentials, and obtains versioned search tools from the configured service.

AI rationale

Evidence

package.jsonscripts/patch-pi.jsdist/index.jsdist/agent-setup.jsdist/search-tools.jsdist/secret-env.jsdist/update.js

Decision evidence

public snapshot

AI called this Clean at 88.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

The manifest has a postinstall hook for a package-owned patch script; the inspected script describes applying runtime patches to the bundled Pi dependency.
The CLI enters its authenticated agent flow through its normal command path.
Agent setup writes package-named extensions under the agent directory.
Search tools download pinned fd and rg assets from the configured service.
Child-process environment handling strips configured secret variables.
The updater checks the npm registry for this package's latest version.
