The FBI has hit upon a wizard wheeze to stuff up whistleblowing websites.
According to Wired, it is seeding boobytrapped files with false information so that it can see a paper trail from the leaker to the published source.
The Pentagon-funded researchers have worked out that they can spot leakers by seeing how they search. They are then pushed towards decoy documents that will give them away.
Dubbed "Fog Computing" it has come out of the brains at DARPA. Researchers say they have built "a prototype for automatically generating and distributing believable misinformation ... and then tracking access and attempted misuse of it. We call this 'disinformation technology.'"
The only problem with the cunning plan is that the method is similar to those used by spammers and they could wind up undermining trust among the spooks.
But the US military feels it should be doing something to stop people leaking secrets which show the nation doing things that it only attributes to autocratic dictatorships.
While most accept that whistleblowing is a way to keep companies clean, the US government still thinks that its more dubious antics should be kept out of public view.
