The Justice Department says it foiled a plot by a fired Fannie Mae contract worker in Maryland to destroy all the data on the mortgage giant's 4,000 computer servers nationwide. The U.S. Attorney's Office says 35-year-old Rajendrasinh Makwana, of Glen Allen, Va., is scheduled for arraignment Friday in U.S. District Court in Baltimore on one count of computer intrusion. U.S. Attorney Rod Rosenstein says Makwana was fired Oct. 24. Rosenstein says that on that day, Makwana programmed a computer with a malicious code that was set to spread throughout the Fannie Mae network and destroy all data this Saturday. Makwana's federal public defender did not immediately return a call seeking comment.
