We have long known that the possibility of attacks on Supervisory Control and Data Acquisition (SCADA) systems was a very real threat to our modern way of living. These systems routinely control how power, water, nuclear, manufacturing, and oil and gas are managed and distributed, forming part of our Critical National Infrastructure (CNI). Attacks on CNI are nothing new, and there are examples where these digital attacks have the potential of affecting our lives in very real ways.
The Stuxnet worm raised the attention of every cybersecurity practitioner in the land. Almost like the plot line of a spy thriller movie, this computer worm, once installed on the network, sought out specific software on computers controlling programmable logic controllers (PLC). It was programmed to hide its presence as it caused the fast-spinning centrifuges to tear themselves apart, making it one of the first forms of malware which impacted the physical world. Stuxnet was highly effective in its targeting of control systems. It is thought to have infected over 200,000 computers and physically damaged 1,000 of them.
