Hunt Hypothesis

The hypothesis is that the detection identifies potential adversary use of IperiusRemote, a Remote Management and Monitoring tool, to establish persistence or command and control channels by leveraging file signature anomalies. SOC teams should proactively hunt for this behavior in Azure Sentinel to detect and mitigate advanced persistent threats that abuse legitimate RMM tools for covert operations.
