“But it is the special computers run by the special operating system. This system is absolutely not known on west. AFAIK it is early some clone of Unix.”
We have teenagers that hack into our best DOD computers.
Nothing is impenetrable. Any operating system can be taken over simply by the fact that it is an OPERATING SYSTEM SOFTWARE and a COMMAND is a COMMAND. The OS doesn’t know where the commands come from and doesn’t care.
Computers do what you tell them to do, if you know how to tell them. Believe me. I have spent most of my career making computers do exactly what I am asked to make them do.
Computers are only capable of doing three things, actually.
Reading, writing, and comparing binary digits. They can only do one type of math with these skills and that is that they can add two binary digits. (by comparing, then writing)
They can’t even subtract. They have to use addition to subtract.

I work in IT too. And I know that if you do not know the command structure then you can’t do nothing. Simply the military computer won’t understand you. But in those military OS even command structure is the secret. And it is changed time to time. The all internal trafik is encrypted so as the data on the hard memory. You can do nothing.
