at Natanz’ nuclear facility
Stuxnet malwareattacked the Pipeline system
According to security firm Symantec, Stuxnet probably arrived at Iran's Natanz nuclear program on an infected USB.
The worm took advantage of 4 unknown weaknesses in Microsoft's Windows OS.
We must make the pipeline system works properly
Pipeline system
1
Inputs and outputs of microcontrolers through the pipelines
Scheme of the pipeline system
In Natanz, the pipeline system must continue working, Even if it is not complete. We sent some small microcontrolers to get the data from the different zones.
Some microcontrolers go throught the pipes
We need to get the amount of microcontrolers that go out in D node.
We can enumerate from x1 to x8 the amount of microcontrolers per pipeline.
Our first step is to close the node E
After closing node E, we force to close the circulation between A and C.
What is the amount that circulates between B and D?
Good luck!
The answer is a no. with 3 digits
