Hunt Hypothesis

The hypothesis is that an adversary is using DameWare Remote Management Tool to establish persistence or command and control by leveraging its file signature for covert communication. SOC teams should proactively hunt for this behavior in Azure Sentinel to identify potential abuse of legitimate RMM tools by threat actors.

KQL Query

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

| where Signer has 'DameWare Development'
| summarize FirstSeen=min(Timestamp), LastSeen=max(Timestamp), 
    Report=make_set(ReportId), Count=count() by DeviceId, DeviceName
