The U.S. FBI has released news that its "Operation Bot Roast" has identified over one million victim computer IP addresses being used in criminal activity. The arrest of three men accused of using the army of hijacked computers for spam related crime was also announced.

The Operation Bot Roast cyber crime project is an ongoing investigation that was launched to battle the growing botnet threat and to create public awareness about Internet security.

While the FBI admits that one of the challenges in fighting this type of cyber crime is that PC users do not have an easy way to tell if their computers have been infected, officials are asking that cyber crime victims file a complaint online through the Internet Crime Complaint Center.
