Someone sprung a leak! And it's still a bit difficult to tell where it came from.

According to Julian Assange, (and the lawyers representing Wikileaks), it was a reporter working for
The Guardian.
The Guardian has
denied all responsibility. The trouble, Wikileaks alleges, all started when
The Guardian's, David Leigh, published a lengthy encryption key in the February 2011 publication
Wikileaks: Inside Julian Assange's War on Secrecy. The key was given to Leigh by Assange so that he could access an online file containing more than 250,000 uncensored US State Department diplomatic cables.
The point of contention could simply be miscommunication between Assange and Leigh.
The Guardian claims both parties agreed the diplomatic cables would be available on an online server in July 2010 for a period of hours, after which, the files would be removed and the temporary server turned off. Assange denied this account in a recent interview with
New Scientist, "The only thing that was temporary was the website location the file was stored in. But the password is not used for the website – it is used for decrypting the file."
However, the plot seemingly thickens, as questions remain over where and when the first bittorrent leaks occurred and at what point Wikileaks became aware that the files had become public. The
BBC bluntly stated, "It has long been known that Wikileaks lost control of the cables even before they were published and that encrypted files are circulating on the internet."
The Guardian also claims that after the initial leaked file surfaced on bittorrent, "At about 11pm on Wednesday [Aug. 31] an anonymous Twitter user discovered the published password and opened a separate file – not the one shared with the Guardian – that had also been circulating on file-sharing networks for several months."
What is clear is that at some point, the encrypted files containing the diplomatic cables had found their way onto bittorrent. However, writing for
The Guardian, James Ball reports that the bittorrent file had not yet been discovered by the public: "By 10am on Thursday [Sept. 1] it had been accessed once in the previous 31 days, despite mounting speculation about its existence."
The accusations flying between Wikileaks and
The Guardian continue to mount. The news organization defended its publication of the encryption key:
It's nonsense to suggest the Guardian's WikiLeaks book has compromised security in any way. Our book about WikiLeaks was published last February. It contained a password, but no details of the location of the files, and we were told it was a temporary password which would expire and be deleted in a matter of hours. It was a meaningless piece of information to anyone except the person(s) who created the database. No concerns were expressed when the book was published and if anyone at WikiLeaks had thought this compromised security they have had seven months to remove the files. That they didn't do so clearly shows the problem was not caused by the Guardian's book.
