- High spikes + correlated support cases = active incidents requiring faster triage and possibly increased staffing.
- Sustained increase in downloads without incidents = growing adoption, wider deployment, or heavier reliance on diagnostics.

- Presence of downloads from unexpected geographies or from third-party hosting may indicate abuse or malware posing as the toolkit.
