I don’t buy this for a minute. PLC’s can easily be replaced and reprogrammed. Unless the software commanded the machinery to destroy itself this is bad reporting...
My understanding is that it did exactly that.
I also read in a previous article that a number of Iranian scientists who were unable to solve the production issues met with "untimely deaths" before the virus was known to be the cause of their issues.
What I understand is that the malware lies dormant and can be turned on and off. And then it infects the PC all over again.
You if you were on a contained network, you would have to wipe each and every operating system clean. And, still, install new—proven clean versions of the new operating system into the computers.
And this assumes that the malware came from “outside.” It might be possible that the malware is actually part of the operating system—written from the outside and brought in.
Consider that the virus is made of two programs and are just waiting to meet. Virus A came in on the machines that does task A. Virus B comes in on PC B. Alone they are benign. When the two systems meet—violins, flowers, and mayehm. And since the malware is PART of the clean OS, it will take a long time to figure out where part A and B are. And you have to rebuild the system every time you make a mistake.
Brilliant stuff....
