Please forgive, and correct, me if I have this wildly wrong: This is referred to as Stuxnet 2. And the original was "proven" to have been made to attack Irania

Please forgive, and correct, me if I have this wildly wrong: This is referred to as Stuxnet 2. And the original was "proven" to have been made to attack Iranian nuclear labs, and what not. Conclusion being that it was made by some government agency. I suppose foil hat theory would point fingers at CIA/NSA type people. Assuming the above is correct, or correct enough, its it not surprising to see what might be a new language for this virus, if it has a nation state's resources behind it? If that is the case, what chance is there that any one will be able to crack this mystery?
