Hunt Hypothesis

This hunt targets adversaries leveraging known 32-bit malicious web endpoints to deliver payloads or exfiltrate data from legacy systems within the Azure environment. Proactively hunting for these specific URLhaus indicators in Azure Sentinel is critical because 32-bit applications often lack modern security controls, making them high-value entry points for sophisticated threats that standard network rules might overlook.
