You may recall that late last week Spanish Police arrested three men that they claimed were connected to hacktivist group Anonymous. The police alleged that the trio were responsible for hacking various web sites associated with Sony, BBVA and Bankia, ENEL, and the governments of Egypt, Algeria, Libya, Iran, Chile, Colombia, and New Zealand.
At the time the group's official Twitter account offered an ominous message to law enforcement: "expect us." And so they came and went. The hackers managed to keep www.policia.es offline for about an hour from 2130 GMT on 12 June.
Spanish authorities did not confirm that Anonymous was behind the attack, saying only that the site was offline. But according to a post on a website associated with the hacking group, they have claimed responsibility for the attack. The assault campaign has been dubbed "OpPolicia."
The group also said it had used a popular method for taking down web sites: a distributed denial of service attack (DDoS), which hammers a target with an overload of data that usually makes it crash.
Anonymous also denied that the three men that were arrested last week were part of the "core" of the Spanish chapter of the group.
"They did not arrest any core group, because we don't have a core group," said Anonymous in its statement.
