Hunt Hypothesis

This hunt detects adversary activity linked to the ClearFake campaign by identifying matches against a curated set of 23 specific indicators of compromise within Azure Sentinel logs. Proactively hunting for these signals is critical due to the high severity of ClearFake’s known tactics, enabling the SOC team to rapidly identify and contain potential infections before they escalate into broader incidents.
