The Post-Bulletin reports that Minnesota's Olmsted Medical Center (OMC) recently began notifying more than 500 former employees that their personal information may have been exposed (h/t Becker's Hospital Review).

In a statement, OMC spokeswoman Jeremy Salucks said the medical center "became aware of unlawful and unauthorized electronic access to information stored in OMC's employee database" on February 3, 2014.

"This breach is similar to the complex tax-fraud breaches occurring throughout the world right now," Salucka said. "At this time, we have no evidence that this breach includes any protected health information (PHI) of OMC employees, their spouses/partners, or dependents. We also have no evidence at this time that this data breach involves any protected health information for any of our patients."

All affected employees, spouses and defendants are being offered one free year of identity theft protection services.

Rochester, Minn. police later told the Post-Bulletin that the stolen data appears to have involved employee W-2 tax forms, and Salucks said a total of 682 current OMC employees have received identity theft protection services.
