Sony remains high atop the hit list of the Anonymous hacktivist gang. The group said Friday that it is responsible for temporarily defacing the website and Facebook account belonging to Sony Pictures. Last last month, the collective posted a YouTube video warning it would retaliate against Sony for its support of the proposed Stop Online Piracy Act (SOPA), which critics say amounts to an internet censorship bill. Last June, Anonymous hijacked SonyPictures.com to steal the personal information on one million people.
