Hunt Hypothesis

The hypothesis is that an adversary is using UltraViewer, a Remote Management and Monitoring tool, to create processes for persistence or establish command and control channels. SOC teams should proactively hunt for this behavior in Azure Sentinel to identify potential compromise of endpoints managed by RMM tools.

KQL Query

let Time_start = now(-5d);
let Time_end = now();
