American venture capitalist John Doerr has been hacked

In an email sent to the smoking gun, the hacker 'Guccifer' claimed that he had hacked the AOL account of American venture capitalist John Doerr.
The hacker provided proof of his act by sending the agency screenshots of Doerr's AOL address book from Doerr's email which include, email addresses of AOL co-founder Steve Case, Biographer Walter Isaacson and Kleiner Perkins employees---the agency which Doerr is a general partner.
The reason why 'Guccifer' hacked Doerr's email account remains unknown.But, John Doerr is not the first victim of the hacker 'Guccifer'. The hacker had gained access to several email accounts of notable Americans, such as George W. Bush sister, Dorothy Bush Koch, former secretary of state Collin Powell and former UN secretary of state, Hillary Clinton.
