Hours after this incident, the internet group Anonymous began a series of DDoS attacks that crippled and eventually took down sites such as; Universal Media Group, RiAA, MPAA, the U.S. Department of Justice official website, and the U.S.Copyright Office.
The french copyright authority HADOPI has also been taken down, as well as music label BMI
This is the largest recorded DDoS attack in history as reported by Russian news service RT, with over 5600 DDoS Zealots blasting at once.
Will continue to update as this story develops.
Update:
The website for the U.S. Federal Bureau of Investigation has also been attacked and taken down.
Anonymous has issued a statement regarding what they are calling Operation Megaupload, I will not post the link to the statement as it contains links that are designed to launch DDoS attacks using the users' own computer. I will however post a link to a video statement that they released.
