Thomas Reed's At The Abyss recounts how the United States exported control software that included a Trojan Horse, and used the software to detonate the Trans-Siberian gas pipeline in 1982. The Trojan ran a test on the pipeline that doubled the usual pressure, causing the explosion.
[...]The software sabotage had two effects, explains Reed. The first was economic. By creating an explosion with the power of a three kiloton nuclear weapon, the US disrupted supplies of gas and consequential foreign currency earnings. But the project also had important psychological advantages in the battle between the two superpowers.
"By implication, every cell of the Soviet leviathan might be infected," he writes. "They had no way of knowing which equipment was sound, which was bogus. All was suspect, which was the intended endgame for the entire operation."
