Change Healthcare, a key player in U.S. healthcare technology, has been suffering from service disruptions affecting hospitals and pharmacies nationwide for over a week, following a cyberattack identified as a ransomware intrusion by TechCrunch.
An executive in the health sector familiar with the situation reported on the briefing held by Change Healthcare’s top executives, revealing the BlackCat ransomware group as the perpetrators of the assault.
As Reuters initially covered, the link between the ransomware group BlackCat and the incident has been confirmed by individuals with intimate knowledge of the circumstance.
A representative for Change Healthcare was contacted but has yet to provide commentary on the matter.
Although the BlackCat ransomware group, also known as ALPHV, has not officially taken responsibility, such groups commonly release parts of data exfiltrated from victims to coerce a payment. These kinds of cyberattacks often involve both the encryption of the victim’s data and a prior theft of information.
The extent to which patient data may have been compromised remains uncertain.
UnitedHealth Group, which owns Change Healthcare and is the largest health insurer in the United States, mentioned in a regulatory filing the detection of a “suspected nation-state” entity within its network, yet did not associate the activity with any specific nation or state.
There is a lack of clarity regarding the attribution of the cyberattack since there is no prior evidence connecting the BlackCat group to any nation-state actors as per cybersecurity experts.
Change Healthcare, a significant force in the American healthcare technology sector, manages a vast network of prescription processing for over 67,000 U.S. pharmacies. It is responsible for approximately 15 billion healthcare transactions every year, encompassing about one-third of all U.S. patient records.
In a move completed in 2022, Change Healthcare was acquired by healthcare services firm Optum as part of a $7.8 billion deal, itself a part of UnitedHealth Group. This merger extended Optum’s reach into the patient databases managed by Change Healthcare.
UnitedHealth Group serves more than 53 million customers in the U.S., with an additional five million internationally, according to its latest annual earnings report. Optum alone caters to roughly 103 million customers stateside.
The disruptive cyberattack on Change Healthcare’s operations began on February 21 and led to the company taking a large segment of its systems offline to eject the cyber intruders.
Updates on the company’s incident tracker page indicate that most customer-facing services have not been reactivated.
Reports from hospitals and pharmacies suggest an inability to process prescriptions and billing via patient insurance systems due to the outage.
The American Hospital Association (AHA) alerted its network, consisting of over 5,000 healthcare institutions, advising them to disconnect from Optum until it is verified to be secure again and highlighted the cyberattack’s “significant cascading and disruptive effects.”
Columbia University’s alert to its medical staff included directives to sever all connections with UnitedHealth Group, Change Healthcare, and Optum, coupled with an email domain blockade.
Furthermore, Tricare, which insures U.S. military staff, acknowledged the cyberattack’s impact on global military and select national retail pharmacies in their statement.
