The truth is, ransomware assaults on well being care targets had been on the rise even earlier than the Change Healthcare assault, which crippled the United Healthcare subsidiary’s capacity to course of insurance coverage funds on behalf of its well being care supplier purchasers beginning in February of this yr. Recorded Future’s Liska factors out that each month of 2024 has seen extra well being care ransomware assaults than the identical month in any earlier yr that he is tracked. (Whereas this Might’s 32 well being care assaults is decrease than Might 2023’s 33, Liska says he expects the more moderen quantity to rise as different incidents proceed to come back to mild.)
But Liska nonetheless factors to the April spike seen in Recorded Future’s information particularly as a possible follow-on impact of Change’s debacle—not solely the outsize ransom that Change paid to AlphV, but in addition the extremely seen disruption that the assault induced. “As a result of these assaults are so impactful, different ransomware teams see a possibility,” Liska says. He additionally notes that well being care ransomware assaults have continued to develop even in comparison with general ransomware incidents, which stayed comparatively flat or fell general: The primary 4 months of this yr, as an illustration, noticed 1,153 incidents in comparison with 1,179 in the identical interval of 2023.
When WIRED reached out to United Healthcare for remark, a spokesperson for the corporate pointed to the general rise in well being care ransomware assaults starting in 2022, suggesting that the general development predated Change’s incident. The spokesperson additionally quoted from testimony United Healthcare CEO Andrew Witty gave in a congressional listening to concerning the Change Healthcare ransomware assault final month. “As we’ve addressed the numerous challenges in responding to this assault, together with coping with the demand for ransom, I’ve been guided by the overriding precedence to do every part potential to guard peoples’ private well being data,” Witty informed the listening to. “As chief government officer, the choice to pay a ransom was mine. This was one of many hardest choices I’ve ever needed to make. And I wouldn’t want it on anybody.”
Change Healthcare’s deeply messy ransomware scenario was difficult additional—and made much more attention-grabbing for the ransomware hacker underworld—by the truth that AlphV seems to have taken Change’s $22 million extortion price and jilted its hacker companions, disappearing with out giving these associates their lower of the earnings. That led to a extremely uncommon scenario the place the associates then provided the information to a distinct group, RansomHub, which demanded a second ransom from Change whereas threatening to leak the data on its dark web site.
That second extortion risk later inexplicably disappeared from RansomHub’s website. United Healthcare has declined to reply WIRED’s questions on that second incident or to reply whether or not it paid a second ransom.
Many ransomware hackers nonetheless extensively imagine that Change Healthcare really paid two ransoms, says Jon DiMaggio, a safety researcher with cybersecurity agency Analyst1 who regularly talks to members of ransomware gangs to assemble intelligence. “Everybody was speaking concerning the double ransom,” DiMaggio says. “If the folks I’m speaking to are enthusiastic about this, it’s not a leap to suppose that different hackers are as effectively.”
The noise that scenario created, in addition to the dimensions of disruption to well being care suppliers from Change Healthcare’s downtime and its hefty ransom, served as the right commercial for the profitable potential of hacking fragile, high-stakes well being care victims, DiMaggio says. “Well being care has at all times had a lot to lose, it’s simply one thing the adversary has realized now due to Change,” he says. “They only had a lot leverage.”
As these assaults snowball—and a few well being care victims have seemingly forked over their very own ransoms to manage the injury to their life-saving techniques—the assaults aren’t prone to cease. “It’s at all times regarded like a straightforward goal,” DiMaggio notes. “Now it appears like a straightforward goal that’s keen to pay.”
Up to date 6/12/24 9:35am ET: This story has been up to date to replicate that ransomware incident totals comprise the fist 4 months of the yr, not simply April.
