Another great summary from Brian Krebs. No matter which side you fall on politically, this stuff should concern you. The problem isn't whether there is hacking, the problem is that we can't even believe the official responses so it leaves a vacuum of information that is readily filled with bullshit.
The public might also be deeply suspicious of hacking claims from a government that practically invented the art of meddling in foreign elections. As Nina Agrawal observes in The Los Angeles Times, the “U.S. has a long history of attempting to influence presidential elections in other countries – it’s done so as many as 81 times between 1946 and 2000, according to a database amassed by political scientist Dov Levin of Carnegie Mellon University.” Also, when it comes to hacking power plants, the U.S. and Israel have probably done more damage than anyone else with their incredibly complex Stuxnet virus, which was created as a weapon designed to delay Iran’s nuclear ambitions and opened a virtual Pandora’s Box.
