Hunt Hypothesis

This detection identifies adversary activity involving the AdaptixC2 command and control infrastructure by monitoring for matches against a curated set of twelve specific indicators of compromise. Proactive hunting in Azure Sentinel is essential to rapidly uncover early-stage lateral movement or data exfiltration attempts driven by this threat actor before they escalate into broader incidents.
