Anonymous have posted another YouTube video, this time declaring an imminent attack on the New York Stock Exchange website. In support of the on-going Occupy Wall Street protests, which began nearly a month ago on September 17, and in direct response to the large scale arrests carried out by the New York City Police Department, Anonymous have issued a two minute video rallying its members to "DDoS attack" the NYSE website at 3:30pm ET on 10th October.
This is the same tactic used to bring down Visa.com, where they flooded the servers and crashed them. it is believed that if the attack is successful, it won't halt or affect trading on Wall St, as it runs through a separate data center. The website does however, host other important information such as trading notices and market activity.
