 This is the VOA Special English Technology Report. Microsoft says it is making progress in efforts to stop the cyber crime operation known as Zeus. In March, federal officials in the United States raided office buildings in two states. They seized evidence related to the Zeus family of malicious software. Richard Boskovich is with the Microsoft's Digital Crimes Unit. He says the objective of the raids was to seize evidence which might help identify the individuals behind the Zeus family of malware. The bigger goal is to identify the computers of people all over the world that are compromised. That means they have the malware on their computer which is being used to victimize others and they don't even know about it. Cyber criminals use Zeus to create a network of infected computers or botnet to steal personal information from computer users. Mr. Boskovich says the operation reaches around the world. He says this malware was present at any given point in time in at least 13 million computers worldwide. Malware means malicious software. It also can be called a computer virus or worm. Mr. Boskovich says the malware is spread through emails where people are tricked into clicking on a link or visiting a website. Once that happens, the objective is to infect the person's computer with this piece of malware. The malware is programmed to record every keystroke as you type on a computer keyboard. It gathers details about the websites you visit, your user names and passwords or other personal information. The information is then sent to the botnet's command center which is a location on the internet. From there, the criminals will direct all of the infected computers to contact the botnet from time to time to ask for directions. Much of the stolen information is sold on the black market. The information can be used to steal money from bank accounts or make purchases online without the victim's knowledge. Officials say these malware invasions are one of the main causes of identity theft. Microsoft brought a case against the Zeus operation on March 19th. The company released the details of the case after the buildings were raided on March 23rd. Next week, we'll talk more about the raids, Zeus, and what Microsoft says computer users can do to protect themselves. We will also talk about other recent efforts to fight cybercrime.
