@factiii/runner@0.9.2

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 malicious under the lifecycle policy because no npm install hook mutates a foreign control surface. It warrants warning because runtime pairing can modify user-scoped agent configuration and trigger global updates.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

User runs setup/start and connects a paired Factiii client.

Impact

Paired-client control can alter CLI agent configuration and replace the globally installed runner.

Mechanism

paired remote update plus user-scoped MCP registration

AI rationale

Decision evidence

public snapshot

AI called this Suspicious at 84.0% confidence as Dangerous Capability with low false-positive risk.

Evidence for warning

Paired DataChannel update command installs @factiii/runner@latest globally and restarts.
Workspace provisioning modifies user-scoped Claude and Codex MCP registrations.
First start installs bundled index dependencies with npm.

Evidence against

package.json has no preinstall, install, or postinstall lifecycle hook.
Agent configuration and updates occur only after explicit setup/start and paired runtime use.
No confirmed credential exfiltration to an unrelated endpoint was found.
