Security Generate Security Sample Data

If you're working with Elastic Security and need realistic test data to validate your dashboards, alerts, or Attack Discovery features, this generates ECS-compliant security events and multi-step attack scenarios. It's from the official Elastic agent-skills repo and includes a demo walkthrough script that spins up sample data and opens Kibana for you. Useful for testing detection rules without waiting for real incidents or manually crafting synthetic events. The generated data populates all the right places in Elastic Security, so you can see how your setup handles actual attack patterns. Saves you from the tedious work of creating believable security event data by hand.
