Hunt Hypothesis

This hunt detects adversary behavior where compromised hosts communicate with known botnet command-and-control domains identified by URLhaus, signaling potential malware propagation or data exfiltration. Proactively hunting for these specific malicious URLs in Azure Sentinel is critical to rapidly identify and isolate infected endpoints before they establish persistent network footholds within the enterprise environment.
