The news we have known since late November and early December of this year 2010, especially those where the power of Internet communications has been involved, we have released a news portal called WikiLeaks, a site specializing in filtering documents dominant considered secret by governments, whose owner, Julian Assange, is being held to encourage the dissemination of information "classified" by world governments, especially the United States. Because of this situation has arisen in the world, especially in the social networks that make working life in the cyberworld of the Internet, a spontaneous movement that claims to fight for freedom of expression on the Internet and threatened to boycott all those services support portal action against WikiLeaks and its leader. This has led many analysts to talk about a new style of warfare, the so-called "cyber" or "Cyber ​​War" in which "nobody can feel safe." Following this confrontation is the refusal to Amazon.com to continue to cast their hosting services to WikiLeaks, as well as receipts and payments company PayPal, by blocking the account from the same portal. As a result, the group "anonymous", a group of computer hackers, has been blamed for cyber attacks carried out against MasterCard's website, Amazon, PayPal, among other objectives, in retaliation for the decisions of these companies against Wikileaks. The attack was to bring down the websites of these companies by the saturation of simultaneous requests that exceed their ability to meet them. Many anonymous requests on a page make it collapse and block its ability to respond. The system crashes while the operation, ie, the ability to receive and process insurance payments are not affected. The attack on PayPal, for failing to manage the transfer of donations to Wikileaks, meant eight hours of interruption of the website and the services of popular payment system. As a result, American society PayPal online payment account reactivated WikiLeaks, unlocking its funds, but imposed certain restrictions that prevent you from taking new donations until further notice this while clarifying whether the dissemination of such news , considered as "state secrets" may be criminalized or not. All this shows, once again, the changing and the truly real is the cyber world. Internet are the streets of the future, as analysts say, and this will automatically lead to more crime and terrorism issues. The crimes appear to move in that direction, while the detection mechanisms will be criminals, I believe, more and more sophisticated. These events produce an escalation of attacks and counter attacks that culminate in laws, restrictions and controls on the use of information on the Web and making virtual media as fields of protests and even battles. Funding agencies, such as PayPal and the like, take appropriate steps to ensure safe monetary transactions and users to take appropriate action on the case. No doubt, Internet is becoming increasingly more real and tangible. It is not in danger of financial security over the Internet, but the freedom to express political views that go against the interests of world powers. To increase security on the Internet there are many locking mechanisms, but the defense of freedom of expression has infinite ways to express, no matter the terrain or the country they are made.
