Hunt Hypothesis

This hunt targets adversary activity linked to the ClearFake malware campaign by correlating network and endpoint telemetry against a curated set of 68 specific Indicators of Compromise (IOCs). Proactively hunting for these signatures in Azure Sentinel is critical to rapidly identify early-stage infections and prevent lateral movement before the threat escalates across the organization’s cloud infrastructure.
