"According to National Security Council staffer Thomas Reed, the CIA got wind that the Soviets were trying to steal industrial-control software for a new gas pipeline from a Canadian supplier. He claims the CIA installed a trojan into the Canadian firm's software and allowed it to be purloined by the KGB.
"The pipeline software that was to run the pumps, turbines and valves was programmed to go haywire, to reset pump speeds and valve settings to produce pressures far beyond those acceptable to the pipeline joints and welds," he said. "The result was the most monumental non-nuclear explosion and fire ever seen from space.""
Oh come on now! You steal some control software from a Canadian company and plonk it on your own pipeline - just like that - and it misbehaves. Well whadya know! If you did that it'd be 99.9% likely to blow up with or without the Trojan.
It'd need configuring (at the very least) for your own use and if you didn't test it pretty damn thoroughly you could expect disaster for sure. If you steal some software there are no guarantees. It might not even be finished.
I'm afraid that story is just not plausible unless you don't have a clue about writing and testing software, like I suspect Thomas Reed doesn't.
