Screenshots with personal information and protected health information were leaked on the dark web after a cyberattack that hit UnitedHealth business Change Healthcare in February according to a release.
The ransomware attack that has engulfed U.S. health insurance giant UnitedHealth Group and its tech subsidiary Change Healthcare is a data privacy nightmare for millions of U.S. patients, with CEO Andrew Witty confirming this week that it may impact as much as one-third of the country. As one of the largest healthcare companies in the U.S., UnitedHealth is well known domestically, intersecting with every facet of the healthcare industry from insurance and billing and winding all the way through the physician and pharmacy networks -- it's a $500 billion juggernaut, and the 11th largest company globally by revenue.
Two months after hackers broke into Change Healthcare systems stealing and then encrypting company data, it’s still unclear how many Americans were impacted by the cyberattack. Last month, Andrew Witty, the CEO of Change Healthcare’s parent company UnitedHealth Group, said that the stolen files include the personal health information of “a substantial proportion of people in America.” On Wednesday, during a House hearing, when pushed to give a more definitive answer, Witty testified that the breach impacted “I think, maybe a third [of Americans] or somewhere of that level.”
UnitedHealth Group Chief Executive Officer Andrew Witty told senators on Wednesday that the company has now enabled multi-factor authentication on all the company’s systems exposed to the internet in response to the recent cyberattack against its subsidiary Change Healthcare. The lack of multi-factor authentication was at the center of the ransomware attack that hit Change Healthcare earlier this year, which impacted pharmacies, hospitals and doctors' offices across the United States. Multi-factor authentication, or MFA, is a basic cybersecurity mechanism that prevents hackers from breaking into accounts or systems with a stolen password by requiring a second code to log in.
Health insurance giant UnitedHealth Group has confirmed that a ransomware attack on its health tech subsidiary Change Healthcare earlier this year resulted in a huge theft of Americans' private healthcare data. UnitedHealth said in a statement on Monday that a ransomware gang took files containing personal data and protected health information that it says may "cover a substantial proportion of people in America." The health insurance giant did not say how many Americans are affected but said the data review was "likely to take several months" before the company would begin notifying individuals that their information was stolen in the cyberattack.
Conservative think tank The Heritage Foundation said on Friday that it experienced a cyberattack earlier this week. A person with knowledge of the cyberattack told TechCrunch that efforts at Heritage were underway to remediate the cyberattack, but said that it wasn't immediately known what, if any, data was taken. Politico, which first reported the news of the cyberattack on Friday, cited a Heritage official as saying the organization "shut down its network to prevent any further malicious activity while we investigate the incident."
