Hunt Hypothesis

This hypothesis targets adversaries leveraging known 32-bit malicious URLs to execute payloads or establish command-and-control channels, often exploiting legacy architecture vulnerabilities. Proactively hunting for these indicators in Azure Sentinel allows the SOC to identify compromised endpoints or suspicious web traffic before the malicious URLs trigger further lateral movement or data exfiltration.
