Spanish Botnet Called Strong Enough to Paralyze Country's PCs

Spanish criminals who stole bank details from computers around the world did not realize the power of the illegal network they had created which could have paralyzed an entire country's computer systems, police said. Police believe the men were not expert hackers and bought their virus program on the black market before using it to take over other people's computers in order to create a "botnet," a network of enslaved computers.
