Application Exhaustion Flood
Adversaries may target resource intensive features of applications to cause a denial of service (DoS), denying availability to those applications. For example, specific features in web applications may be highly resource intensive.
Detect it with
Detection of Endpoint DoS can sometimes be achieved before the effect is sufficient to cause significant impact to the availability of the service, but such response time typically requires very aggressive monitoring and responsiveness.
Why it matters on shift
Application Exhaustion Flood is one of the concrete ways adversaries achieve impact. Recognising it in telemetry lets you name the technique in your ticket and pivot to what came before and after.
What to look for next
After impact, the next tactic is usually Impact. Search your telemetry for the transition before closing the ticket.
