This hunt targets adversaries leveraging known 32-bit malicious web resources to establish initial footholds or deliver payloads within the organization’s network traffic. Proactively hunting for these specific URL signatures in Azure Sentinel is critical because it enables the SOC team to identify and block early-stage infection vectors before they propagate across legacy systems that rely on 32-bit architectures.
