Backup tapes containing sensitive data on 4.9 million active and retired U.S. military personnel recently went missing. Data on the tapes included Social Security numbers, names, addresses, phone numbers and personal health information.

"It is not immediately clear how or when Science Applications International Corporation (SAIC), a contractor for the military, discovered the breach," writes Computerworld's Jaikumar Vijayan.

"Vernon Guidry, vice president for media relations at SAIC, said the removable backup tapes were among items reported stolen from an employee's car," Vijayan writes. "In an emailed statement, Guidry said the SAIC employee was transferring the tapes between federal facilities in San Antonio when they were stolen."
