Not-for-profit mental health center Emergence Health Network, located in El Paso, Texas, has announced that its computer servers were compromised “through an unauthorized internet connection” from as far back as 2012.

The center discovered the compromise in August when it “became aware of strange activity on one of our computers.”

A forensic analysis revealed that an unauthorized person gained access to the system through an Internet connection, and the first “unapproved access of the server may have happened back in 2012.”

The intruder had access to over 11,000 mental health patients’ names, addresses, dates of birth, Social Security numbers, case numbers and information that the individuals sought services at the center. The center stated “we are confident that no medical records were contained within the server.”

Nonetheless, the disclosure of the sensitive mental health records was reported to the Office for Civil Rights and the affected patients.
