The Associated Press reports that celebrities, including Ashton Kutcher and Kim Kardashian, along with top government officials have had private financial information stolen and posted to a rogue website.

The AP says that the FBI was also investigating how the social security number, address and a credit report of FBI Director Robert Mueller ended up on the site. According to reports, the reason for the data thefts and subsequent publication was not made clear on the web site nor were there many clues to the origin of the site or the perpatrators. A Twitter account linked to the site carried an anti-police message in Russian, which at present appears to be the only lead.

The list of names put up on the site appears to be growing as the FBI and Secret Service joined forces to investigate what may be the start of a sustained criminal hacking campaign.
