Hunt Hypothesis

This hunt detects adversary activity by correlating network and endpoint logs against 87 specific indicators of compromise (IOCs) linked to the ClearFake malware campaign. Proactively hunting for these IOCs in Azure Sentinel is critical because ClearFake employs sophisticated evasion techniques that often bypass standard signature-based defenses, requiring manual validation to confirm early-stage infections before lateral movement occurs.
