I don't know about the veracity of the "Massive Cyber Attack..." but attacks like that aimed at our financial institutions, public utilities, and military bases are just around the corner...and in some cases have already taken place.
Cyber War! Likely to catch most of us by surprise. What a mess that will be. I'm not a survivalist but making some type of plan like having extra cash on hand, ammo, water, medicines and food to last awhile seems to be a good idea to me.
