Any techies out there actually believe this? I don’t for a second. Even with the worst possible computer virus total recovery could be done in 36 hours. Worst case scenario, you remove all network connectivity and format all computers. What functionality does networking my computers do to allow or disallow the operation of my nuclear faciltiy. Even if my equipment was designed to operate on an internal LAN, I certainly don’t need it to be connected to any outside network. Perhaps a virus took them out of operation momentarily, but its just not magick.
I think you need to read up on how stuxnet works before you post.
Stuxnet destroyed the centrifuges. Can't 'unring' that bell by 'taking equipment of the LAN'. Calling all techies. An educational opportunity awaits.
