Michelle Obama's social security number hacked from data brokers' network

U.S. First Lady Michelle Obama's social security details have reportedly been hacked from networks of American data brokers.

An investigation into the matter revealed that the hackers, who run an online market for confidential data, compromised computers on the data brokers' corporate networks to steal millions of ID numbers, the BBC reports.

The mysterious website, exposed.su, blamed to be behind the hack attack had earlier in March published confidential information about Bill Gates, Beyonce Knowles, Jay-Z, Ashton Kutcher and many others.

The matter was investigated by the Krebs, the FBI and US Secret Service which revealed that exposed.su had bought its information from another site, called SSNDOB.

SSNDOB sold data records of individuals for even a minimum amount of 50 cents, the report added.

Krebs named companies like LexisNexis, Dun and Bradstreet and Kroll, who are well known for providing businesses with data about potential commercial partners and customers, for their compromised computers as the sources of the data.
