Have you even bothered to find the article I mentioned?
Just because what you cite doesn't mention the lose of control for 12 to 18 hours in early 2001 doesn't mean diddly.
I could cite stuff like that and ask similar questions while knowing all along that what I'm citing is inaccurately cited as proof.
The SCADA network was hacked.
As far as I know it has not been hardened against attack.
After the blackout, the SCADA network was looked at, but brushed off as a method of taking down the northeast tier.
Matter of fact, there have been arrogant types claiming that it is impossible to take down the northeast tier power grid.
Just like arrogant types claimed that tehre would never be an attack on Americans on American soil.
