Hide AdIts website states its modus operandi is to provide an "innovative, secure and anonymous way for sources to leak information to our journalists".
Its secretive way of operating has resulted in a series of dramatic exposs.
Among a long list of high-profile stories are revelations about the controversial belief system of scientology, disclosures on the treatment of prisoners at the Guantanamo Bay detention centre and the publication of the names and addresses of members of the far right British National Party.
WikiLeaks came in for concerted military criticism this summer after publishing confidential documents concerning the war in Afghanistan.
But it nonetheless followed up the expos with a further release of classified papers from the Iraq conflict.
Led by Australian Julian Assange, these latest revelations will surely go down as one of the group's highest-profile coups.
And as WikiLeaks has proved time and time again, there will be more to come.
