"This white paper highlights a number of the destructive malware families analyzed by the Industrial Control Systems Cyber Emergency Response Team (ICS-CERT) and gives recommendations for victims on the best way to combat each specific family. Destructive malware attacks are simple and fast to execute. In many cases, once the user knows that something odd is occurring on the system, it is already too late to do anything about it. Careful preparation and planning before an attack is the best mitigation against destructive malware."
