Hunt Hypothesis

This detection identifies adversary behavior where endpoints download known malware from a curated set of 35 malicious URLs flagged by URLhaus. Proactively hunting for these downloads in Azure Sentinel is critical to intercept early-stage infection vectors before they establish persistence or propagate lateral movement across the network.
