Hunting for Impersonated domains and users

Threat Explorer (P2) and Real-time detections (P1) are powerful near real-time tools to help Security Operations teams investigate and respond to threats. Today we provide existing pivots for Detection Technology with User impersonation or Domain impersonation which show all Phish emails caught by our impersonation detection. We are adding new pivots called Impersonated user and Impersonated domain within Threat Explorer to enable Security Operations teams to explicitly hunt for specific protected users or domains within their organization that are targets of impersonation attacks. This additional information related to Impersonated domain(s) and Impersonated user(s) will also be shown in existing Impersonation insight pages and our new Email Entity page.
