A ransomware gang, Interlock, has claimed responsibility for the hack on Kettering Health, a network of hospitals, clinics, and medical centers in Ohio, which forced the healthcare system to shut down all computer systems for two weeks.
Interlock stated they stole more than 940 gigabytes of data from Kettering Health and published some of the stolen data, including private health information and employee data, on their dark web site.
Interlock's public acknowledgment of the breach could indicate that negotiations with Kettering Health have stalled, potentially leading to the exposure of the stolen data. Kettering Health's senior vice president stated that the company did not pay any ransom to the hackers.
Kettering Health was able to restore core components of its electronic health record system provided by Epic, marking a significant step towards normal operations post-cyberattack.
