It was just a matter of time before industrial wars were fought on the grid. My experience in the industry gives me a gut feeling that Israeli agents are the genesis of this worm. Their engineers would be considered savants in any other society.
All hail to them (unless they point it at us!).
Years and years ago our office got regular visits by FBI agents interested in the comings and goings of one of our employees due to his advanced use of modems and such.
This was way back in the mid-1970s.
Seems he could call up modems at CIA's Langley headquarters and make them deliver the goods (so to speak).
I can only imagine that 35 years of R&D has improved everyone's skill levels!
