The ransomware group allegedly behind a recent cyberattack at UnitedHealth’s (NYSE:UNH) Change Healthcare unit is claiming it stole millions of records, including data from partners such as Medicare, the US military’s TriCare and CVS Health (NYSE:CVS), according to Reuters.
The hacker group, known as Blackcat and ALPHV, posted the claims on its dark web site but quickly deleted them. Cybersecurity researchers have since shared screenshots of the group’s claims online, Reuters said. Reuters added that it was unable to verify the group’s claims at this time.
Reuters said UnitedHealth was aware of the hackers’ statement and was “looking into it.” CVS Health also said it was aware of the statement, but that Change had not yet confirmed whether any CVS Health or CVS Caremark information was impacted by the hack.
The Centers for Medicare and Medicaid Services and Tricare did not immediately respond to Reuters’ requests for comment. TriCare has said all of its military pharmacies were impacted by the hacking incident, Reuters added.
Blackcat has a track record of going after corporations, including attacks last year on MGM Resorts (MGM) and Caesars Entertainment (CZR), Reuters said.
