A Department of Defense employee had thousands of dollars stolen from his personal bank accounts by perpetrators. He informed his superiors and is concerned his work and home computers may be infected with malware. The Department of Defense contacted GTSI, a military security contractor, to investigate and examine DoD devices and the employee's home computer to look for malware. It is possible the malware is the Zeus Trojan. GTSI was tasked to research the Zeus Trojan and write a report describing how it has been used, how to detect it, and how to remove it.
