The thing is, that can't!
Now that the public has seen an especially disturbing specimin, they will have developed a natural immune response to all similar legal viruses!
But seriously, the leak of that, even if fake, will have quadrupled(at least) the number of people who will scrutinize anything even remotely similar, with the terror of absolute governmental control of the entire internet as a looming shadow of the future.
Likely, half the army would quit(Though this is just speculation, living in a diffrent country and all), if not more, and anyone with an atom of ethics will refuse to implement it, for fear of the force that will be required to enforce it fully(Borders on global thermonuclear war).
The USB storage and custom OS industry will skyrocket, as well as the existance of self-organizing WIFI network software that would allow all computers with the capability to join together to share information.
The information spread speed would diminish rapidly, but if such networks grew around intercontenental trunk lines of unimpeded data transmission, as well as any unmonitored or unblockable internet link, everything will proceed as usual, only the governments will have lost all hope of control, short of militart force, and even that would result in riots and military deserters.
There, I have predicted the results of 2012, the fall of the internet as we know it, and rise of the NewNet, a place where true anonymity is possible, and nobody can even own a fraction of what an ISP does today.
