Hunt Hypothesis

This rule detects the presence of known indicators of compromise associated with the “Unknown RAT” malware family, which often leverages these IOCs for initial access or command-and-control communication. Proactively hunting for these signatures in Azure Sentinel allows the SOC team to identify compromised endpoints or network artifacts before the adversary can establish persistence or execute lateral movement within the environment.
