In 1981 the French Directorate of Territorial Security (DST) flipped the high ranking KGB agent Colonel Vladimir who provided invaluable intelligence such a list of Soviet agents operating within the United States borders along with their intelligence targets. Control software for gas pipelines was found to be on the list and as a result the CIA set out to leak a tampered version of the software to one of the newly discovered agents. Then in 1982 the software, which was deployed on a Trans-Siberian gas pipeline, triggered a colossal explosion and "was the most monumental non-nuclear explosion and fire ever seen from space". This and other interesting stories are the focus of this talk about the forgotten history of cyber warfare.
