Ransomware attack on US dental insurance giant exposes data of 9 million patients

“An apparent ransomware attack on one of America’s largest dental health insurers has compromised the personal information of almost nine million individuals in the United States. The Atlanta-based Managed Care of North America (MCNA) Dental claims to be the largest dental insurer in the nation for government‑sponsored plans covering children and seniors. In a notice posted on Friday, the company said it became aware of “certain activity in our computer system that happened without our permission” on March 6 and later learned that a hacker “was able to see and take copies of some information in our computer system” between February 26 and March 7, 2023. “

“The information stolen includes a trove of patients’ personal data, including names, addresses, dates of birth, phone numbers, email addresses, Social Security numbers and driver’s licenses or other government-issued ID numbers. Hackers also accessed patients’ health insurance data, including plan information and Medicaid ID numbers, along with bill and insurance claim information. “

“In some cases, some of this data pertained to a patient’s “parent, guardian, or guarantor,” according to MCNA Dental, suggesting that children’s personal data was accessed during the breach. “

“However, the LockBit ransomware group took responsibility for the cyberattack and claims to have published all of the files it exfiltrated from MCNA Dental after the company refused to pay a $10 million ransom demand. “
