Spanish authorities, with the help of private cyber security companies, have identified and arrested three individuals, whose online names are "jonyloleante," aged 30, "netkairo," 31, and "ostiator," 25. The three were identified as the ring-leaders of a massive botnet know as "mariposa." The network was started in 2008 and infected nearly 13 million computers. Over half the Fortune 1000 companies were infiltrated by the botnet, including over 40 major banks. The botnet was present in nearly 200 countries. Criminals purportedly used the botnet to steal identities, generate spam, and attack online targets. The individuals face up to six years in prison if convicted.
