Sony has been a major target of hackers ever since it's ill-fated lawsuit against George "Geohot" Hotz. The PlayStation Network attack has drawn attention from the FBI, the Department of Justice, Congress, and the New York State Attorney General. Sony responded via letter to the House of Representatives Subcommittee on Commerce, Manufacturing and Trade on Wednesday, defending their response to the PSN attack. Now, it appears that Sony is a target once again. A group of hackers is apparently planning a major attack against Sony's website this weekend.
