Hunt Hypothesis

This hunt detects adversary activity linked to the ClearFake threat by identifying matches against a specific set of 33 Indicators of Compromise (IOCs) known to be associated with this campaign. Proactively hunting for these IOCs in Azure Sentinel is critical because it enables the SOC team to identify early-stage infections and potential lateral movement before they escalate into full-scale incidents, leveraging high-severity alerts to prioritize immediate response actions.
