There is a Wikileaks fiasco going about. Der Spiegel has what looks like a plausible story. If you read the Wikileaks version after that, the latter looks rather incomplete and self-serving. The Grauniad also says “not us guv” which isn’t quite true: if they hadn’t been dumb enough to publish the password, all would have been well. But assuming DS has this right, fundamentally this is a Wikileaks foul up.

[Update: no-one has dented the DS story as far as I can see. So I think that, as told, this remains fundamentally a WL foul up. However (whilst I think the Grauniad were correct to believe that the password they'd got was now irrelevant) they (a) should not have published it, just on general sanity grounds (b) they should not have published it because they could not be confident that they hadn't ended up with a backup of the file themselves, somewhere]
