Stopping Ransomware Before It Disrupts Care

In healthcare, every minute counts. During an adversarial exercise, a U.S. hospital detected a simulated ransomware outbreak at the lateral movement stage, before encryption began.

Ransomware is loud at the end and quiet at the start. By the time files begin locking, the operator has already been inside for days, mapping the environment and positioning. The detectable window is the reconnaissance and lateral movement that precedes it, and that activity is carried out with valid credentials and trusted administrative tools.

That is why the detection has to come from behavior rather than signatures. The operator is using the same tools your administrators use, so the question is not what is running but whether this account has ever done this before.
