Authorities in Spain have arrested three men accused of operating a massive botnet composed of 12.7 million PCs, which stole credit card and bank log-in data and infected computers in half the Fortune 1,000 companies and more than 40 banks, according to published reports.

The botnet 'Mariposa', which means butterfly in Spanish, first appeared in December 2008 and grew to be one of the largest botnets ever, The Associated Press reported. It spread the worm via removable drives, MSN Messenger and peer-to-peer programs, and targeted Windows XP and older systems.

Unlike many underground hackers, the alleged ringleaders of the operation were not skilled programmers, but had contacts who were, authorities said.
