Hunt Hypothesis

This hunt targets adversary behavior characterized by the execution of unknown malware signatures across the network, specifically leveraging a set of 32 distinct indicators of compromise to identify early-stage infections. Proactively hunting for these IOCs in Azure Sentinel is critical because it enables the SOC team to detect and contain novel threats before they escalate into widespread incidents that evade standard signature-based defenses.
