A corporate saboteur manages to get into his competitor's building and finds the computer of one of the system admins left on running scans. Excited with the opportunity he rushes over to the computer and starts poking around, and to his delight, the sysadmin has setup a method in which he can remotely turn on all computers and remotely download a program and install it on all computers, on the network. So the saboteur knowing he doesn't have a lot of time, quickly writes a small program that runs this fork bomb, %0|%0|%0. He then installs it on all the computers and makes it so that it runs on startup (all computers on the network are windows). Then he remotely shuts down all computers, including the one he is on.
There are about 300 computers on the network, and this is the corporations only location.
Booting from another disk/drive is prevented as a security precaution, so booting from another disk or drive attached is not an option.
How damaging would this attack be to the corporation assuming that the program that started the fork bomb executed whenever the computer turned on?
How would the corporation recover from such an attack?
Note: Any feedback on improving the question is appreciated. If anything is unclear and needs more explanation, please let me know and I will do my best to explain it better.
