Hunt Hypothesis

This hunt identifies potential botnet command-and-control infrastructure by correlating network traffic with known malicious domains registered in the URLhaus database. Proactively hunting for these indicators in Azure Sentinel allows the SOC to detect compromised assets communicating with botnet nodes before they can be leveraged for lateral movement or data exfiltration.
