Hours after unnamed hackers exposed financial records of high-profile celebrities including Jay-Z, Beyoncé Knowles-Carter and Britney Spears, new reports claim the information has also been used.

Rather than soaking in the publicity, the hackers have taken things up a notch and used the info for their own personal gain.

The hackers who obtained Michelle Obama’s financial records — along with some of the biggest celebs in the world — aren’t just seeking recognition … law enforcement sources tell TMZ they have been “using” the credit information. Our sources would not be specific on how the information has been used, but it could involve access and withdrawal of money. As we previously reported, the hackers have obtained personal banking information as well as social security numbers and that could be enough to obtain withdrawals of cash. We’re also told the FBI has been “aggressively investigating” the case … and it also strikes close to home, because one of the victims is FBI Director Robert Mueller. Our sources also make it clear … the FBI knew about the hackers before they made themselves public. We’re told, “The investigation did NOT start yesterday.” (TMZ)

Not only targeting music celebrities, victims have included a slew of Hollywood stars like Paris Hilton and Kim Kardashian.

Add hackers to the list of Jay-Z’s 99 problems: the rapper, along with wife Beyoncé, was one of a bevy of stars whose financial records have been exposed and posted online. Britney Spears, Vice President Joe Biden, former Secretary of State Hillary Clinton, Ashton Kutcher, Kim Kardashian, Paris Hilton, Mel Gibson, and former presidential candidate Sarah Palin are among those who have been targeted by the website, which has an Internet suffix assigned to Russia. Some of the information posted includes Social Security numbers, which makes identity theft easily available for potential defrauders. (Rolling Stone)

President Barack Obama‘s wife, First Lady Michelle Obama, has also fallen victim to the mysterious hackers.

A growing number of bigs in entertainment and politics — including Jay-Z and Beyoncé, Michelle Obama and Hillary Clinton — were hacked and had their financial details or sensitive material published online. The LAPD — whose top cop, Charlie Beck, was among the victimized luminaries — is trying to track down the vicious hacker who supplied material to the website, exposed.su, police sources said. Also victimized were Kim Kardashian, Britney Spears, Donald Trump, Paris Hilton, Mel Gibson, Ashton Kutcher, Vice President Biden, FBI Director Robert Mueller, Attorney General Eric Holder, Arnold Schwarzenegger, Hulk Hogan and Sarah Palin.

The criminals have directed interested people to a website where personal information including Social Security numbers, mortgage accounts and more sensitive records.

The site’s main page, titled “The Secret Files,” has a picture of a gaunt teenage girl in zombie-like makeup shushing the viewer. Music from Showtime’s “Dexter” plays in the background as visitors are invited to click on a celebrity’s name and receive info including addresses, Social Security numbers, mortgage accounts and credit card numbers and bank accounts.
