Delta Dental of Arizona has reported an incident that may affect the privacy of certain information and advises potentially affected individuals to take steps to better protect their personal information. The company notes that it has not received any reports that personal information has been misused as a result of the incident. 

On or around July 8, 2019, Delta Dental of Arizona became aware of suspicious activity related to an employee’s email account. The company says it immediately commenced an investigation, working with third party investigators, to assess the nature and scope of the email account activity. 

The investigation confirmed that the employee fell victim to an email phishing scheme that allowed an unauthorized individual to gain access to the email account on July 8, 2019. While Delta Dental of Arizona has no evidence of actual or attempted misuse of any information in the email account, it could not rule out the possibility of access to data in the account. 

Delta Dental of Arizona says that it undertook a lengthy and labor-intensive process to identify the personal information in the affected account. The company now is notifying individuals because it has confirmed that certain personal information was present in the affected email account.

Delta Dental of Arizona was unable to confirm whether the unauthorized individual actually accessed any information. However, the investigation did determine that the information in the account may include:

  • Name
  • Address
  • Date of birth
  • Social Security number
  • Member or subscription identification number
  • Driver’s license number
  • Government issued identification number
  • State identification number
  • Passport number
  • Financial account information
  • Credit and/or debit card information
  • Dental treatment information
  • Dental insurance information
