Dental and vision insurance provider and administrator Dominion National has begun notifying patients of a data breach of its systems that apparently dates back to August 2010. The insurer said an incident investigation that began on April 24, 2019, led to the discovery that its servers had been compromised in an attack that began nearly nine years ago.

"Dominion National moved quickly to clean the affected servers. Dominion National has no evidence that any information was in fact accessed, acquired, or misused," the firm said in a press announcement.

The compromised servers store enrollment and demographic information of Dominion National and Avalon vision programs, as well as of patients whose dental and vision benefits are administered by the firm. Names, addresses, email addresses, dates of birth, Social Security numbers, taxpayer identification numbers, bank account and routing numbers, member ID numbers, group numbers, and subscriber numbers are among the types of data on the servers.
