Hunt Hypothesis

This hunt detects adversary activity consistent with the ClearFake malware campaign by identifying network connections and file artifacts matching its specific set of 56 Indicators of Compromise (IOCs). Proactively hunting for these signals in Azure Sentinel is critical to rapidly identify early-stage infections and prevent lateral movement before the threat escalates into a full-scale breach.
