The ransomware group N0n claims to have stolen member data from dental benefits insurer Delta Dental of Missouri, listing the company on its leak site on November 5.
The group claims the files include members’ names, Social Security numbers, dates of birth, home addresses, and dental treatment details, as well as more than 48,500 email addresses and 17,900 phone numbers. None of the claims have been independently verified. Delta Dental of Missouri stated that it has engaged independent forensic specialists and that its systems and services remain operational.
The incident is unrelated to the 2023 MOVEit breach reported by Delta Dental of California and its affiliates. Because the insurer is a HIPAA-covered entity, any member notification duties would fall to the plan rather than to dental practices. Practices should still watch for insurer-themed phishing aimed at billing staff, according to Medix Dental IT.
