Which dataset is most appropriate for IOC hunting?

The xdrdata dataset is the most appropriate for Indicator of Compromise (IOC) hunting because it contains the comprehensive raw telemetry collected from all sensors, including endpoints, networks, and cloud environments. This dataset includes detailed event logs for process executions, file activities, network connections, registry modifications, and more. Threat hunters use the Query Language (XQL) to search this vast repository for specific IOCs (e.g., file hashes, IP addresses, domains) to uncover evidence of malicious activity that may not have triggered a formal alert or incident. This proactive searching of raw data is the core of threat hunting.
