@factiii/runner@0.13.0

Factiii Runner, run Board AI agents on a machine you control. Pairs with the Factiii web/mobile clients over WebRTC.

AI Security Review

scanned 2mo ago · by lpm-firewall-ai

This is not concrete malware or install-hook abuse because npm installation has no lifecycle trigger and no external secret exfiltration was established. The automatic user-scoped Claude/Codex extension and secret-command bridge warrant a warning.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

A user configures and starts the Factiii runner, then provisions a workspace.

Impact

Future supported agent sessions can load Factiii hooks and request commands with selected secrets, expanding the agent control surface.

Mechanism

Automatic user-scoped agent plugin, MCP, hook, and secret-command bridge setup.

AI rationale

Evidence

dist/cli.jsplugin/factiii/hooks/hooks.jsonplugin/factiii/bin/factiii-secrets

Decision evidence

public snapshot

AI called this Suspicious at 90.0% confidence as Dangerous Capability with low false-positive risk.

Evidence for warning

Starting a configured runner automatically provisions plugins and MCP entries for Claude and Codex.
The provisioner installs a user-scoped plugin and suppresses command failures.
The shipped plugin executes a status script on multiple Claude lifecycle events.
A bundled helper sends selected secret-key requests and a command to the runner over a local socket.

Evidence against

The manifest has no npm install lifecycle hook; prepublishOnly is publish-time only.
The observed hook script exits unless it finds a local Factiii Redis socket.
No source evidence shows secret values sent to an external endpoint or an unconsented install-time action.
