Anonymous is upset at Sony for supporting the SOPA act, and is threatening to shut down its network again. The hacker group also threatened Justin Bieber, Lady Gaga, Kim Kardashian, and Taylor Swift.

Here is the full text of their threat:

"Hello, SONY.
We are Anonymous.

It has come to the attention of the Anonymous activist community that you have chosen to stand by the Stop Online Piracy Act. This act will halt online businesses and restrict access to many sites for many users. Supporting SOPA is like trying to throw an entire company from off a bridge. Your support to the act is a signed death warrant to SONY Company and Associates. Therefore, yet again, we have decided to destroy your network. We will dismantle your phantom from the internet. Prepare to be extinguished. Justice will be swift, and it will be for the people, whether some like it or not. Sony, you have been warned.

To those doubting our powers. We've infiltrated the servers of Bank of America, The United States Department of Defense, The United Nations, and Lockheed Martin. In one day.

For their approval to SOPA, we have also declared that our fury be brought upon the following persons. Justin Bieber. Lady Gaga. Kim Kardashian. and Taylor Swift.

Operation Blackout, engaged.
Operation Mayhem, engaged.
Operation LulzXmas, engaged.

We are Anonymous.
We are Legion.
We do not forgive.
We do not forget.
Supporters of SOPA, you should've expected us."

Now might be a good time to change your PSN password and grab Rochard off the PlayStation Network.
