Michelle Obama Hacked: First Lady, Celebrities Reportedly Fall Victim To 'Doxxing'

First Lady Michelle Obama is reportedly being counted among the victims in a string of recent high-profile personal security breaches.

On Monday, TMZ first reported that upwards of 12 celebrities and political figures -- like Jay-Z, Beyonce, Kim Kardashian, Ashton Kutcher and Paris Hilton -- had been hacked. Financial and personal information, including social security numbers, bank accounts, mortgage information and credit card details, were "doxxed" (posted online) to the website Exposed.su by a group of Russian hackers.

Michelle Obama was thrown into the hacking mix on Tuesday, when TMZ revealed the website had published her credit report. Along with this credit report was her social security number, phone number and credit card information. A message on the website reads, "Blame your husband, we still love you, Michelle."

Gawker reported that the hackers also posted the First Lady's Banana Republic and Gap credit card information. (While FLOTUS' bills seem to be in order, Jay-Z allegedly owes $227,115 on his American Express Card.)

Other political heavyweights reportedly affected include Vice President Joe Biden, Hillary Clinton, Eric Holder, Sarah Palin and FBI Director Robert Mueller, according to the New York Daily News.

An FBI spokesperson told The Huffington Post that it is looking into the website where the information appeared.

Former FBI agent Brad Garrett spoke with ABC News about the alleged hacking and raised the possibility of a hoax. "I'm very suspect [about] information released online. It goes against the very reason you steal them, it's to use them," Garrett said. "Is this a prank? Is this a hoax? Is it to get attention? That wouldn't surprise me one bit."

However, in another development on Tuesday morning, TMZ reported that the celebrity hackers have been "using" the credit information. TMZ claims that the FBI has been "aggressively investigating" the case and knew about the doxxing before it was made public.

This incident comes just three months after Florida native Christopher Chaney was sentenced to 10 years in prison for hacking into the email accounts of celebrities Scarlett Johansson, Mila Kunis, Christina Aguilera, Simone Harouche and Renee Olstead. Chaney exposed online the stars' personal content, including naked photos.
