The US Department of Health and Human Services said that an Indiana medical software company has told that the confidential information of approximately 3.9 million people in the country was exposed after its networks were hacked.

On June 10, it was announced by the Fort Wayne company that the hacking of its main network in addition to its NoMoreClipboard network started on May 7 and was detected on May 26. According to the company, names, addresses, dates of birth, Social Security numbers as well as health records were included in the information that was exposed.

According to a notice that was posted on the company's website, the hack had an influence on patients of some health care providers. Texas-based Concentra that operates over 300 medical centers in 38 states; Rochester Medical Group in the Detroit area; and Franciscan St. Francis Health Indianapolis are among them.

As per the notice, the hack also affected patients from 44 hospitals and other radiology centers in Ohio, Indiana and Michigan. The Indiana and Purdue university medical centers were among the providers. According to the notice, an investigation by a team of third-party experts indicates that this could be a complex cyber-attack.

According to Michael Stephens, director of the Indianapolis VA Regional Office, "We had a tough year; we know that. I'll tell you, there has been a lot of good work going on, a lot of progress, not just here in the state of Indiana but across the U. S. in terms of serving veterans better".
