Ohio-based healthcare provider Kettering Health cancelled patient procedures and appointments following a cyberattack that crippled its systems. The non-profit, which operates 14 hospitals and over 100 outpatient facilities across the state, confirmed the incident on Tuesday, May 20.
The cyberattack significantly impacted Kettering Health’s call centers and patient care systems, prompting the cancellation of both elective inpatient and outpatient procedures. The organization assured patients that affected appointments would be rescheduled and updates would follow.
“Our call center is also down and may be unreachable at this time,” the company stated, urging patients to remain alert to phishing scams. Kettering Health warned that scammers might attempt to exploit the situation and emphasized that it would temporarily suspend phone-based payment requests as a precaution.
According to CNN, the ransomware group Interlock has claimed responsibility for the attack. The group threatened to leak sensitive data unless a ransom is paid, stating, “Your network was compromised, and we have secured your most vital files.”
Interlock, an emerging ransomware gang active since late 2024, has gained notoriety with a string of attacks—16 confirmed and 17 unverified, according to Rebecca Moody, head of data research at Comparitech. The group previously breached DaVita, a national kidney care provider, and recently targeted a school network in West Lothian, Scotland, leaking 3.3 million files online.
Kettering Health continues to assess the damage and work toward restoring systems while cooperating with authorities.
