Health care giant comes clean about recent hack and paid ransom

After burrowing into the Change Healthcare network undetected for nine days, the attackers deployed ransomware that prevented the company from accessing its IT environment. In response, the company severed its connection to its data centers. The company spent the next two weeks rebuilding its entire IT infrastructure “from the ground up.” In the process, it replaced thousands of laptops, rotated credentials, and added new server capacity. By March 7, 99 percent of pre-incident pharmacies were once again able to process claims.

Witty also publicly confirmed that Change Healthcare paid a ransom, a practice that critics say incentivizes ransomware groups who often fail to make good on promises to destroy stolen data. According to communications uncovered by Dmitry Smilyanets, product management director at security firm Recorded Future, Change Healthcare paid $22 million to ALPHV. Principal members of the group then pocketed the funds rather than sharing it with an affiliate group that did the actual hacking, as spelled out in a pre-existing agreement. The affiliate group published some of the stolen data, largely validating a chief criticism of ransomware payments.

“As chief executive officer, the decision to pay a ransom was mine,” Witty wrote. “This was one of the hardest
decisions I’ve ever had to make. And I wouldn’t wish it on anyone.”

Bleeping Computer reported that Change Healthcare may have paid both ALPHV and the affiliate through a group calling itself RansomHub.

Two weeks ago, UnitedHealth Group reported the ransomware attack resulted in a $872 million cost in its first quarter. That amount included $593 million in direct response costs and $279 million in disruptions. Witty’s written testimony added that as of last Friday, his company had advanced more than $6.5 billion in accelerated payments and no-interest, no-fee loans to thousands of providers that were left financially struggling during the prolonged outage. UnitedHealth Care reported $99.8 billion in sales for the quarter. The company had an annual revenue of $371.6 billion in 2023.

Payment processing by Change Healthcare is currently about 86 percent of its pre-incident levels and will increase as the company further restores its systems, Witty said. The number of pharmacies it serves remains a “fraction of a percent” below pre-incident levels.
