Hunt Hypothesis

This hunt targets adversaries leveraging ELF-based malware distribution through known malicious URLs identified by URLhaus to execute payloads on Windows systems. Proactively hunting for these indicators in Azure Sentinel is critical because it enables the early detection of lateral movement and initial compromise vectors before they escalate into full-scale infections across the organization’s endpoint fleet.
