An Indian contract computer engineer who worked for Fannie Mae has been indicted by a federal grand jury for installing a software bomb designed to destroy all the data in Fannie Mae's computer system. The contractor, Rajendrasinh Babubhai Makwana, had been fired by Fannie Mae.
According to the indictment, on the day the contractor was fired, the malicious code was placed at the end of a routine computer program scheduled to run each morning. Set to execute on Jan. 31, 2009, the code was programmed to attack all 4,000 of the company's servers and would have wiped out all the data on them. It was discovered by chance five days later.
