xbot007

Hunt Hypothesis

The xbot007 rule detects potential command and control communication associated with a known malicious botnet, indicating possible compromise of endpoints. SOC teams should proactively hunt for this behavior in Azure Sentinel to identify and mitigate early-stage adversarial activity before it escalates.
