Hunt Hypothesis

This detection identifies potential Remote Access Trojan (RAT) activity by correlating traffic against a set of fifteen unknown Indicators of Compromise (IOCs). Proactive hunting for these signals in Azure Sentinel is critical to uncover stealthy adversary presence before they establish persistent access and exfiltrate sensitive data.
