Spanish police have arrested three men allegedly responsible for the Mariposa botnet which controlled nearly 13 million infected computers.
The botnet was rendered inactive on December 23, 2009 following months of collaboration between security firms Panda Security and Defense Intelligence in co-operation with the FBI, Spain’s Guardia Civil and security experts around the world.
Personal computer users were not the only ones in the bot masters net.
It would be easier for me to provide a list of the Fortune 1000 companies that weren’t compromised,” said Christopher Davis, chief executive of security firm Defence Intelligence.
