Three members of the Anonymous organsation, known for its cyber-presence, have been arrested by Spanish authorities in Barcelona, Valencia and Alicante.
Although Anonymous recently came to the attention of gamers for the now infamous hacking attacks against Sony, they have been attacking big companies for a while. VISA, MasterCard, PayPal and even Scientology have been on the receiving end.
The operation had been underway since 2010 and two of the people didn't even have their own internet connection. Instead, they hacked the WiFi of others.
