Hunt Hypothesis

This hypothesis posits that adversaries are leveraging a set of thirty-two specific 32-bit malicious URLs identified by URLhaus to deliver payloads or facilitate command and control communications within the network. A proactive hunt in Azure Sentinel is critical because early detection of these known malicious endpoints can prevent initial compromise vectors, allowing the SOC team to isolate affected assets before lateral movement occurs.
