[Still Thinking]

Yeah, I was wondering about that myself. Perhaps some of them keep the schematics on the same PCs that are running PCS7 ;-). During the Cold War, the commies had no problems getting the schematics for absolutely anything.

The first is a good point, and the second is for any target of high value to the hacker, as these plants would be in the scenario you describe.

Well, it did enter at least 14 plants, in “the U.K., North America, Korea,” and, mostly, Iran. And it looks like some foreign government is behind this. Even if the sysops were incompetent, it is newsworthy.

Hmmm, true. I guess it IS news after all but the headline should be "Incompetent controls engineers endanger US infrastructure! Immediate corrective action necessary!"

True, hehehe :-)
