Hackers take aim at those who trespass against Wikileaks

Hundreds of hackers and internet activists have banded together in retaliation against the websites of multinational companies who had been hostile to Wikileaks. Included in this group of activists were a group known as Anonymous who conducted the “denial of service” attack against Mastercard. Among other companies targeted in the attacks were Visa, Paypal and Amazon--each playing a role in the destruction of the Wikileaks infrastructure. The activitists used social networks, primarily Facebook and Twitter, to build their cyberwar campaign. The resulting onslaught  brought those websites to a crawl and at moments made them unavailable to the public.
