Why did the Change Healthcare ransomware attack cost so much?Because one stolen credential on an internet-facing remote-access portal without multi-factor authentication let ALPHV/BlackCat affiliates paralyze the largest U.S. medical claims clearinghouse — and health data is the most expensive kind to lose.What happened: On Feb. 21, 2024, attackers logged into a Citrix remote-access portal at Change Healthcare, a UnitedHealth Group subsidiary that processes roughly one in three U.S. patient claims, using credentials later confirmed to be missing MFA. The ALPHV/BlackCat group encrypted the network and reportedly collected a $22 million ransom in March. In January 2025 the company confirmed the breach exposed data on about 190 million people — the largest healthcare data breach on record.Key numbers: About 190 million individuals had personal or health data exposed$22 million ransom reportedly paid to ALPHV/BlackCatRoughly $3.1 billion in 2024 costs attributed to the responseWhy it matters: A single unauthenticated login disrupted pharmacies, hospitals, and rural clinics for weeks, showing that critical infrastructure fails through shared dependencies, not through sophistication.Bottom line: Attackers rarely breach the biggest company — they breach the one login everyone else depends on.
