PART II

This chapter recounts two significant flashbacks illustrating the evolution and potential of cyberwarfare. The first, the Aurora experiment in 2007, demonstrates how a small amount of malicious code can physically destroy a large diesel generator by manipulating protective relays in the power grid. The second flashback traces the origins of state-sponsored hacking back to the 1980s with the Moonlight Maze incident, highlighting the early sophistication and persistence of cyber espionage efforts.
