Every hospital in America felt it. Your CFO called it "the day healthcare stood still."

On February 21, 2024, Change Healthcare, a major claims-clearinghouse responsible for processing a very large proportion of U.S. medical claims, was hit with a BlackCat ransomware attack. It didn't just breach data; it halted billing, claims processing, and insurance verifications nationwide.

I was talking with a CEO whose pharmacy network suddenly couldn't verify insurance, whose billing backlog grew by the day. Patients faced delays in filling prescriptions or getting routine care authorizations, not because of lack of funds, but because critical trusted systems were down.

They had invested in security. They had plans. Yet the attack worked. Why? Because the system was built around a single point of failure. What we called "efficiency" became fragility.

Now most hospitals are asking: "How do we prevent another Change Healthcare?" The real question is: "How do we build systems that don't collapse when the inevitable happens?"

The answer isn't bigger firewalls. It's designing for failure. Distributed fraud detection. Redundant systems. Zero-trust architectures that assume breach, not just try to avoid it.

At CrossClassify, we're helping healthcare organizations build resilient fraud detection that works even when primary systems are compromised. Because the next attack isn't coming. It's already here.

Stop building bigger walls. Start building systems that survive the siege.
