Hackers going by the twitter name of @CabinCr3w were apparantly able to hack Goldman Sachs' computer system. The hackers sent off a tweet that directed followers of their twitter account to the Pastebin website. The Pastebin website allows users to paste information to the website anonymously, where it is stored for a period of time.
The hackers pasted the personal information of Goldman Sachs CEO Lloyd Blankfein, including his age, recent addresses, education and even a listing of the legal cases he has been involved in. The pasted information also included the e-mail addresses and titles of more than eighty employees of Goldman Sachs.
