Hacker group Team Poison said that they have stolen the National Insurance number as well as other personal information of the former UK Prime Minister Tony Blair.

Reports said, that the hackers compromised Blair’s NI number along with contact information of his friends and relatives, which include the personal contact details of Cherie Blair as well.

The leaked file was posted on pastebin.com and certain details of it were also posted on Twitter. The hackers said, they compromised the details on December 2010.

The leaked files include important phone numbers of Labor MP Denis MacShane and the former Lord Chancellor Lord Irvine.

Blair’s spokesperson said that the information was compromised from the personal email account of a former member of staff, and not from his office systems.

The hack, however, has no connection with previous attacks from Lulzsec, ITProPortal reported
