>1982
in 1982, supposedly, cia hackers created an embedded trojan horse command in a microchipset used to regulate/enable gas and pipeline pressure regulation, knowing that the soviets would steal and use such chips. After many thousands of standard use cycles, the trojan command would activate, and instantly and dramatically increase pressure at a specific location and time…
pressurized gas in contained environment exceeding pressure and volume tolerances of the pipe and couplings = EXPLOSION
