Celebrities hacked: Kim Kardashian and Beyoncé among 13 celebrity victims

Sensitive information including Social Security numbers and credit reports of the First Lady, Vice President and numerous Hollywood A-listers have been hacked and posted on to a website, authorities revealed.

The bombshell security breach on Monday has left Los Angeles police and the FBI struggling with how to respond - after the leaders of both agencies were also targeted.

FBI Director Robert Mueller and LAPD boss Charlie Beck weren't alone. Michelle Obama, VP Joe Biden and former Secretary of State Hillary Clinton had their addresses and other sensitive information posted online.

Hacked: The Social Security number and credit reports that allegedly belong to First Lady Michelle Obama have been posted online by hackers

Power couple targeted: Beyonce and Jay-Z are among the celebs whose financial information has been posted on the website

Bold hack: Information posted on Vice President Joe Biden and former Secretary of State Hillary Clinton did not include credit reports but included addresses and other sensitive information

The site, which bore an inteet suffix originating in the Soviet Union, remained active on Tuesday and bears a quote from the TV show Dexter as the tagline: 'If you believe that God makes miracles, you have to wonder if Satan has a few up his sleeve.'

It appears as if the site is continuing to reveal the details of yet more famous people today. The names of Sarah Palin, Hulk Hogan and Aold Schwarzenegger were added to the list on Tuesday.

It is also linked to a Twitter account @exposedsu which has text written in Russian in just two tweets posted since Monday.

.su was a domain used by the Soviet Union for 14 months between 1990 and 1991. It is popular with cyber-criminals carrying out online attacks.

 

Socialites: The social security numbers and credit reports of Kim Kardashian and Paris Hilton were also exposed by the elaborate hack

Several of the purported credit reports appear to have been generated last week. Many of the pages featured unflattering pictures of the celebrities or govement officials whose information was posted.

Michelle Obama's on the other hand is largely positive featuring an 'I Love Michelle' sign and the message: 'Blame your husband, we still love you, Michelle. <3'

The existence of the hacker's website was first reported on Monday by TMZ.  The site reported that both the LAPD and the FBI are investigating the hack.

The site's page on LAPD chief Charlie Beck includes a taunting reference to former police officer Christopher Doer, who was killed in a shootout after killing four people over several days last month.

Beck reopened Doer's case and ordered a review of the LAPD disciplinary system after the black ex-cop's online manifesto accused the department of racism and bias in his firing and vowed to get even with officers and their families

Out in the open: Information belonging to Two and a Half Men star Ashton Kutcher and singer Britney Spears were also revealed by the website

Homage? The site's page on LAPD chief Charlie Beck includes a taunting reference to former officer Christopher Doer, pictured.

Doer killed four people, including two police officers, in his rampage before he committed suicide during a fiery shootout in a Califoia mountain cabin two weeks ago.

Beck's page on the hackers' site included the message '#YouCantCoerTheDoer' and an image of a woman protesting police corruption.

The hacker group Anonymous had threatened a cyber-attack in retaliation to Doer's death last month.

While govement officials often have to disclose details on their finances - and celebrity divorces sometimes feature public financial data - the information posted online exceeds those disclosures.

Social Security numbers are rarely included in public records anymore because they can be used for identity theft.

In December, a man who hacked email accounts belonging to A-listers including Scarlett Johansson, Mila Kunis and Christina Aguilera was sent to prison for a decade.

Christopher Chaney, 36, pleaded guilty to nine felony counts earlier this year - including identity theft, wiretapping, and unauthorized access - after he leaked nude and revealing photos of the women online.

Chaney, of Jacksonville, Florida, was arrested in 2011 as part of a year-long investigation of celebrity hacking that authorities dubbed 'Operation Hackerazzi'.

The depth of his hacking - which kept the unemployed Chaney glued to his computer screen for days at a time - enabled him to witness exchanges between celebrities, their family members and their doctors.

In all he was accused of illegally accessing the private information of around 50 stars with virtually no technical computer training. The 36-year-old also admitted to being privy to information about male stars who were hiding the fact they were gay for the sake of their careers.

Prosecutors said Chaney illegally accessed the email accounts between November 2010 and October 2011.

Nude photos Johansson had taken of herself were later posted on the Inteet. Johansson told Vanity Fair that the photos were meant for Ryan Reynolds, her ex-husband who is now married to Blake Lively.
