"On 29 July 2010 WikiLeaks added a 1.4 GB "Insurance File" to the Afghan War Diary page. The file is AES encrypted and has been speculated to serve as insurance in case the WikiLeaks website or its spokesman Julian Assange are incapacitated, upon which the passphrase could be published, similar to the concept of a dead man's switch. Following the first few days' release of the United States diplomatic cables starting 28 November 2010, the US television broadcaster CBS predicted that 'If anything happens to Assange or the website, a key will go out to unlock the files. There would then be no way to stop the information from spreading like wildfire because so many people already have copies.' CBS correspondent Declan McCullagh stated, 'What most folks are speculating is that the insurance file contains unreleased information that would be especially embarrassing to the US government if it were released' "(Wikipedia article on Wikileaks, accessed 12-08-2010).
