As you may have read this morning the FBI has taken down internet file hosting site MegaUpload for Piracy crimes. It did not take long for Anonymous to respond after hearing the news today. After hearing the news they knocked the following companies websites offline: Justice.gov, MPAA.org, and Universal Music.
This is not the first time Anonymous has attempted at taking down government sites. This comes right after many sites shut down to protest the SOPA bill which is scheduled to be voted on soon. I highly recommend keeping your eye on the news to see what comes out about the bill as the vote gets closer
