So here, what we want to do, is you can run a dictionary
attack or brute force.
What I recommend is get rid of the dictionary attack
to begin with.
I click on those three bars, and I do the Minus Sign.
Under brute force attack, I drag both of the bars to 4 and 4
hoping that the user did a four-digit PIN that's
only numbers.
And then I attempt that attack.
If it fails, I would slide those bars to 6 and 6 and do 0 to 9.
