ABC News reports that approximately 15,000 New York City Metropolitan Transportation Authority (MTA) employees' personal information was recently found on a CD inside a refurbished computer sold at an unidentified "major retailer."

"While we do not suspect nor have seen any evidence of misuse of the data, every precaution is being taken to ensure that this is the case," MTA chief information officer Sidney Gellineau wrote in a March 6, 2014 notification letter to those affected.

The CD contained a list of Social Security numbers, birthdates, salary information and other data for about 15,000 current and former MTA employees at all levels of the organization.

The person who purchased the refurbished computer reported the discovery to her employer, a vendor that works with the MTA. The vendor then gave the CD to the MTA's attorney.

While the presence of the data on the CD was in violation of MTA policy, Gallineau wrote, "We are not aware of any other such violation of the policy."
