In the previous few lessons, we have been discussing the Stuxnet virus. The first virus of its kind. A virus that was created to target the automation industry and specifically, a Siemens PLC running a nuclear enrichment facility. In this lesson, we continue the discussion on the Stuxnet virus and we will give you a reminder on how to detect the virus in your PLC as well as some information as to how to remove the virus from both the PLC and the computer that will be used to download the PLC program. Open up this lesson to find out just how to handle this virus.
