How did the Change Healthcare ransomware attack cripple US healthcare?It crippled claims processing and pharmacy operations nationwide for weeks, forcing UnitedHealth Group to pay a $22 million ransom on March 7, 2024, though the stolen data was still leaked regardless.What happened: The ALPHV/BlackCat ransomware group breached the Change Healthcare subsidiary on February 21, 2024, encrypting critical clearinghouse systems and exfiltrating sensitive health data. The outage cut off payment flows to hospitals and pharmacies for over a month, and UnitedHealth confirmed the ransom payment to Congress while the stolen data still surfaced on the dark web.Key numbers: $22 million ransom paid, yet data still leaked publicly.Up to 1 in 3 Americans' records potentially exposed in the breach.33 days passed before major claims systems were fully restored.Why it matters: A single compromised vendor paralyzed a critical national healthcare backbone, proving that extreme consolidation creates catastrophic single points of failure.Bottom line: Paying the ransom bought no security—only true network segmentation and offline backups could have limited the blast radius.
