Jay-Z, Beyoncé, Kim Kardashian and Michelle Obama are among the 17 well-known and high-ranking Americans whose personal financial information apparently was posted online.

On the home page of the site is a haunting image of a young girl holding one of her index fingers up to her lips (as if to signal "keep this on the hush"), a quote from the TV show Dexter ("If you believe that God makes miracles, you have to wonder if Satan has a few up his sleeve") and the list of celebs and politicians with hyperlinks to pages that detail such information as social security numbers, home addresses and credit reports.

Though all of the information has yet to be verified as accurate, reportedly the FBI and LAPD are investigating (FBI Director Robert Mueller and LAPD Chief Charlie Beck are among the high-ranking political figures targeted on the site).

The Huffington Post published a statement from the LAPD:

"LAPD detectives are investigating the recent disclosure of Chief Beck’s personal information. Apparently this is not necessarily a hacking incident. It is called ‘doxxing.’ This has happened to the chief on two other occasions prior to this in a similar nature post Occupy L.A. ... There will be no further comments or press conference on this matter."

Doxxing, which is essentially cyberstalking to obtain information, is not illegal unless actual hacking is involved.

"We’ll take steps to find out who did this, and if they’re within the boundaries of the United States, we’ll prosecute them," Beck said.

The site appears to have originated in Russia (it has an ".su" country code).

Britney Spears, Ashton Kutcher and Attorney General Eric Holder were among the others exposed on the site. Jay’s and Bey’s teams both have declined comments.
