This hunt detects adversaries leveraging known malicious URLs to distribute malware downloads, a tactic often used in initial access or supply chain compromise scenarios. Proactive hunting is essential within Azure Sentinel to identify and isolate these specific threat vectors before they propagate across the enterprise network, thereby reducing dwell time and potential data exfiltration risks.
