Hunt Hypothesis

This detection rule identifies adversary activity involving known 32-bit malicious URLs from URLhaus, which often serve as initial infection vectors or command-and-control channels for legacy-targeted threats. The SOC team should proactively hunt for these indicators in Azure Sentinel to rapidly isolate compromised endpoints and prevent lateral movement before the malware establishes a persistent foothold within the network.
