If you are even remotely paying attention you already know that top Chinese military was invited to be part of our US military “grid down” exercises a few years back. This hack is IMHO most likley treason from within, not the “Russians”
Either way our entire grid has purposely been left virtually unprotected by elements in our government to help to bring the country down.
The Wall Street Journal has a detailed report out today regarding a sophisticated, and successful attack by hackers into the US electric grid. The hackers could have temporarily shut off power.
The Journal claims Russia is responsible. I hate such assumptions. In the absence of hard proof, the hack could have come from China, North Korea, Israel, or even the US. Even if Russian hackers did this, there is a difference between “Russian” and “Russia”.
