@factiii/runner@0.17.1

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

AI Security Review

scanned 21d ago · by lpm-firewall-ai

Source supports a warning for first-party agent extension installation and automatic updates, rather than the scanner's malicious verdict. The manifest lacks install hooks, and the inspected skill and tmux behavior does not establish an active attack.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review

Trigger

Runtime workspace provisioning or reattachment after starting the configured runner.

Impact

Persistent agent extension changes and later automatic updates can affect agent behavior without a separate update approval.

Mechanism

Shell commands install and update the local Factiii plugin; deployment flows also create a workspace skill link.

AI rationale

Evidence

dist/cli.js.factiii-runner/plugin.claude/skills/deploy

Decision evidence

public snapshot

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

Evidence for warning

The manifest has no registry install hooks or runtime self-dependency; its lifecycle script is prepublishOnly.
Runtime provisioning installs the Factiii plugin into Claude's user scope and adds it to Codex.
The same provisioning flow updates the Claude plugin and runs again when an existing workspace is reattached, without a separate consent prompt in that flow.
Plugin rendering uses the package's local plugin source rather than a fetched remote payload.
The flagged Claude skill mutation links the workspace deploy skill during approval and deployment flows.
The flagged tmux save script writes session layout to local resurrection backups.

Evidence against

No concrete malicious install chain or covert credential theft was established.
The agent changes serve the runner's own plugin and deployment integration.
