As Change Healthcare's outage drags on, fears grow that patient data could be released

A cyberattack at U.S. well being tech big Change Healthcare has floor a lot of the U.S. healthcare system to a halt for the second week in a row.

Hospitals have been unable to test insurance coverage advantages of in-patient stays, deal with the prior authorizations wanted for affected person procedures and surgical procedures, or course of billing that pays for medical companies. Pharmacies have struggled to find out how a lot to cost sufferers for prescriptions with out entry to their medical insurance data, forcing some to pay for pricey drugs out of pocket with money, with others unable to afford the prices.

Since Change Healthcare shut down its community abruptly on February 21 in an effort to include the digital intruders, some smaller healthcare suppliers and pharmacies are warning of crashing money reserves as they wrestle to pay their payments and employees with out the regular movement of reimbursements from insurance coverage giants.

Change Healthcare’s mum or dad firm UnitedHealth Group mentioned in a submitting with authorities regulators on Friday that the well being tech firm was making “substantial progress” in restoring its affected programs.

Because the near-term affect of the continued outages on sufferers and suppliers turns into clearer, questions stay in regards to the safety of hundreds of thousands of individuals’s extremely delicate medical info dealt with by Change Healthcare.

From Russia, a prolific ransomware gang taking credit score for the cyberattack on Change Healthcare claimed — with out but publishing proof — to have stolen monumental banks containing hundreds of thousands of sufferers’ non-public medical knowledge from the well being tech big’s programs. In a brand new twist, the ransomware gang now seems to have faked its personal demise and dropped off the map after receiving a ransom cost price hundreds of thousands in cryptocurrency.

If affected person knowledge has been stolen, the ramifications for the affected sufferers will seemingly be irreversible and life-lasting.

Change Healthcare is without doubt one of the world’s largest facilitators of well being and medical knowledge and affected person data, dealing with billions of healthcare transactions yearly. Since 2022, the well being tech big has been owned by UnitedHealth Group, the biggest medical insurance supplier in the USA. A whole bunch of 1000’s of physicians and dentists, in addition to tens of 1000’s of pharmacies and hospitals throughout the U.S., depend on it to invoice sufferers in accordance with what their medical insurance advantages allow.

That measurement presents a selected danger. U.S. antitrust officers unsuccessfully sued to dam UnitedHealth from shopping for Change Healthcare and merging it with its healthcare subsidiary Optum, arguing that UnitedHealth would get an unfair aggressive benefit by having access to “about half of all People’ medical insurance claims cross annually.”

For its half, Change Healthcare has repeatedly averted saying up to now whether or not affected person knowledge has been compromised within the cyberattack. That has not assuaged healthcare executives who fear that the data-related fallout of the cyberattack is but to come back.

In a March 1 letter to the U.S. authorities, the American Medical Affiliation warned of “important knowledge privateness considerations” amid fears that the incident “brought about in depth breaches of affected person and doctor info.” AMA president Jesse Ehrenfeld was quoted by reporters as saying that Change Healthcare has offered “no readability about what knowledge was compromised or stolen.”

One cybersecurity director at a big U.S. hospital system advised TechCrunch that although they’re in common contact with Change and UnitedHealth, they’ve heard nothing up to now in regards to the safety or integrity of affected person data. The cybersecurity director expressed alarm on the prospect of the hackers doubtlessly publishing the stolen delicate affected person knowledge on-line.

This particular person mentioned that Change’s communications, which have step by step escalated from suggesting that knowledge might need been exfiltrated, all the way in which as much as acknowledging an lively investigation with a number of incident response corporations, recommend it’s only a matter of time earlier than we learn the way a lot has been stolen, and from whom. Clients will bear a part of the burden of this hack, this particular person mentioned, asking to not be quoted by identify as they aren’t approved to talk to the press.

Ransomware gang pulls ‘exit rip-off’

Now, the hackers appear to have disappeared, including to the unpredictability of the scenario.

UnitedHealth initially attributed the cyberattack to unspecified government-backed hackers, however later walked again that declare and subsequently pointed the blame on the Russia-based ransomware and extortion cybercrime group referred to as ALPHV (also called BlackCat), which has no recognized hyperlinks to any authorities.

Ransomware and extortion gangs are financially motivated and sometimes make use of double-extortion ways, first scrambling the sufferer’s knowledge with file-encrypting malware, then swiping a duplicate for themselves and threatening to publish the info on-line if their ransom demand just isn’t paid.

On March 3, an affiliate of ALPHV/BlackCat — successfully a contractor that earns a fee for the cyberattacks they launch utilizing the ransomware gang’s malware — complained in a posting on a cybercrime discussion board claiming that ALPHV/BlackCat swindled the affiliate out of their earnings. The affiliate claimed within the publish that ALPHV/BlackCat stole the $22 million ransom that Change Healthcare allegedly paid to decrypt their recordsdata and forestall knowledge leaking, as first reported by veteran safety watcher DataBreaches.web.

As proof of their claims, the affiliate offered the precise crypto pockets deal with that ALPHV/BlackCat had used two days earlier to allegedly obtain the ransom. The pockets confirmed a single transaction price $22 million in bitcoin on the time of cost.

The affiliate added that regardless of having misplaced their portion of the ransom, the stolen knowledge is “nonetheless with us,” suggesting the aggrieved affiliate nonetheless has entry to reams of stolen delicate medical and affected person knowledge.

UnitedHealth has declined to substantiate to reporters whether or not it paid the hackers’ ransom, as an alternative saying the corporate is concentrated on its investigation. When TechCrunch requested UnitedHealth if it disputed the studies that it paid a ransom, an organization spokesperson didn’t reply.

By March 5, ALPHV/BlackCat’s web site was gone in what researchers imagine is an exit rip-off, the place the hackers run off with their new fortune by no means to be seen once more, or keep low and reform later as a brand new gang.

The gang’s darkish net web site was changed with a splash display purporting to be a legislation enforcement seizure discover. In December, a worldwide legislation enforcement operation took down parts of ALPHV/BlackCat’s infrastructure however the gang returned and shortly started concentrating on new victims. However this time, safety researchers suspected the gang’s personal deception at play, reasonably than one other lawful takedown effort.

A spokesperson for the U.Ok. Nationwide Crime Company, which was concerned within the preliminary ALPHV/BlackCat’s disruption operation final 12 months, advised TechCrunch that ALPHV/BlackCat’s ostensibly seized web site “just isn’t a results of NCA exercise.” Different world legislation enforcement companies additionally denied involvement within the group’s sudden disappearance.

It’s not unusual for cybercrime gangs to reform or rebrand as a approach to shed reputational points, the kind of factor one would possibly do after being busted by legislation enforcement motion or making off with an affiliate’s illicit earnings.

Even with a cost made, there is no such thing as a assure that the hackers will delete the info. A current world legislation enforcement motion geared toward disrupting the prolific LockBit ransomware operation discovered that the cybercrime gang didn’t at all times delete the sufferer’s knowledge because it claimed it will if a ransom was paid. Firms have begun to acknowledge that paying a ransom doesn’t assure the return of their recordsdata.

For these on the front-lines of healthcare cybersecurity, the worst-case state of affairs is that stolen affected person data change into public.

The affected person security and financial impacts of this are going to be felt for years, the hospital cybersecurity director advised TechCrunch.
