Washington (DC) - On October 29, 2008, a vigilant senior Unix engineer happened across a "logic bomb" that was allegedly planted by a contractor, Rajendrasinh Babubhai Makwana, who had worked in their Urbana, MD facility until October 24, 2008 when his contract was terminated. The script was set to activate on January 31, 2009 and would completely wipe all of Fannie Mae's 4,000 servers.
