The hacked nude photographs leaked online of actresses including Jennifer Lawrence and Kate Upton have been traded on the Internet for at least a week and could be just the tip of the iceberg of stolen celebrity pictures. Exchanged on the deep web black market and deviant message boards specializing in stolen 'revenge porn' photography, the compromising pictures have been used as a currency of sorts among perverted members of these forums. Indeed, in the aftermath of Sunday's mass dumping of naked pictures, these boards have descended into anarchy and infighting, with a civil war erupting between those who leaked the pictures and those furious their sordid, secret game has been thrown into the public eye. Worringly for the general public is how simple the posters make their privacy theft seem - and raises the frightening prospect that Apple's iCloud used by millions is not safe for anyone to store sensitive information on. Selfies leaked: Jennifer Lawrence was the victim of a hacker who posted more than 60 revealing images of the actress online.
