The exposed information types included names, addresses, Social Security numbers, dates of birth, phone numbers and tax IDs. ADT confirms that no payment information, including bank accounts or credit cards were exposed.

A total of 331,536 individuals across the United States were impacted, including 32,546 Texas residents, 5,129 Washington residents, 4,540 Massachusetts residents and 702 New Hampshire residents. The company posted a security notice on its website and disclosed the incident to the Securities and Exchange Commission.
