UPDATED: Kim Kardashian, Beyonce, Ashton Kutcher Among Those Targeted in ‘Doxxing’ Hacker Schem

Move over, swatting … there's a new prank in Hollywood, but this one is much more serious.

A dozen celebrities, including Kim Kardashian, Beyonce, Ashton Kutcher, Paris Hilton, and Mel Gibson, all recently had their personal financial information hacked and published online in a cyber-crime called "doxxing."

The unnamed website has reportedly posted the stars' social security numbers, mortgage amounts, credit card information, car loans, and other important banking information. Vice President Joe Biden and former Secretary of State Hillary Clinton were also victims, but apparently not as much of their financial information was obtained.

omg! spoke with the LAPD and FBI, both of which are on the case, but neither could provide many details at this time as the investigation is ongoing, although the FBI did confirm that it's "aware of the website in question."

The FBI also explained that this latest hoax is called "doxxing," which means "the process of obtaining or deducing information about a person based on a limited set of initial information," and that the bureau has had experience dealing with it before.

Ironically, in addition to the celebrities and politicians who were targeted, LAPD Chief Charlie Beck and FBI Director Robert Mueller were also victims.

The LAPD issued the following statement Monday evening: "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 LA. We are not at liberty to discuss the others mentioned in the web post. There will be no further comments or press conference on this matter."

Kutcher and the Kardashian-Jenner family were also the victims in the past several months of "swatting," which involves tricking emergency personnel by making a false report, usually via a 911 call.

A 12-year-old boy has claimed responsibility for the swatting incident involving Kutcher. Last October, he called 911 and claimed people inside the home of the "Two and a Half Men" star had guns and explosives, which, of course, was not true. The same boy was also charged with swatting Justin Bieber, but TMZ reports that charges will likely be dropped when he is sentenced, which is expected to happen soon.
