Well, what do you know? Three suspected members of the Anonymous Hacking group were arrested today in Spain. The arrests were made in Barcelona, Valencia, and Almeria. For those who may have forgotten, the Anonymous hacking group is responsible for the attacks on Sony, Spanish banks, and possibly other attacks.
The arrests were actually as part of an investigation that had begun in October 2010. It looks like some of the attacks made by members of the group used a web-based tool called Loic to bombard the target sites with data. Furthermore, Paypal, Mastercard, and Amazon were each targeted using this tool.
