In the first lesson of this series, we discussed what was considered the first of its kind. A cyber weapon that’s purpose was to invade and stealthily command and hopefully destroy machinery that was controlled by a PLC control system. This weapon or virus appeared to have a specific target and a specific goal. In this lesson, we discuss both the target and the goal as well as the degree to which it worked and how the plot was foiled. Open up this lesson to learn more about the Stuxnet virus, what it did, and how it was discovered.
