Hacker, notable cases and techniques

Anonymous

The wanted hacker that watches over the freedom of expression of the citizens all around the world.

Anonymous is a group of users who protests in support freedom of expression, access to information, the Internet's independence and against various organizations like Daesh or gobernment censorship systems.  

Since there is no hierarchy, it is generally difficult to confirm the authenticity of news or information regarding Anonymous. They are difusely organized on the web, which makes it difficult to find anything official related to them. However, this community of people organizes operations, discusses the state of certain countries and other issues using various online channels.

Because there is no leadership or membership in an administrative sense, and the collaboration has no commitment, its structure can be compared to that of an anarchist movement. 

In January 2011, British police arrested five males between the ages of 15 and 26 suspected of involvement in Anonymous attacks.19 During July 19 and 20, 2011, up to 20 arrests of suspected Anonymous hackers were made in the US, UK and the Netherlands, according to statements by US officials.

On June 9, 2011, the Spanish National Police arrested and later released three people accused of association with Anonymous for allegedly being the administrators of the chats from which they made attacks on web pages. The National Police and numerous media outlets announced that they had dismantled the 'top leadership' of Anonymous. One of the defendants awaiting trial, three years later, publicly stated that the crimes he was accused of were totally false and he had no relationship with Anonymous. The three defendants were acquitted in July 2016, after it was ruled that there was insufficient evidence to link them to the group or to the charges he accused them of.
