Company paid the ransom but it’s not clear if they got all the stolen data back.
On Wednesday, UnitedHealth Group Inc. Chief Executive Officer Andrew Witty was grilled by US lawmakers on Capitol Hill about the devastating hack against its Change Healthcare subsidiary.
He revealed a lot of new details: Hackers encrypted Change’s systems with ransomware, prompting a total rebuild. They also locked backup filed, delaying restoration. The company paid a $22 million ransom in an attempt to protect patient data that was pilfered by the hackers.
What remains unclear — even after more than two hours of testimony that morning — is whether UnitedHealth’s ransom payment did in fact protect patient data, or whether hackers still possess sensitive information that could still be leaked at any given moment.
