Oh is this public now? I remember this, it was hilarious. Imagine what
happens when all your valves go to "open" or "closed" at
once....
It reminds me a bit of the opening scene of Red Storm Rising -- Tom
Clancy's second novel though actually a not well credited collaboration
with Larry Bond, and in some ways more reminiscent of Bond's work than
Clancy's. Great stuff, in any case.

SCADA manufacturer thought
some of their gear was being bought for the trans-Siberia pipeline, and
couldn't be sold for that under trade restrictions. Somebody at that
company got in touch with a contact at the CIA, and asked if they wanted to
insert a "feature" into those units. They put in a time bomb that was
essentially the same as the Y2K shutdown, and blew up the entire pipeline
when all the valves slammed shut at the same time. This info was reported
by the famous Jack Anderson in the Washington Post.
