Brute Force attack on Random Seed.

This applies to the Real Random Seed generated with timing of keystroke.

If we can overhear and store timing of keystroke, we have approximate timing.

If we have seed generator, we can use brute force attack (try all permutations of bits as input for the known seed generator) in time window, with maximum (or perhaps not only) precisions, and we can guess the random seed.

For PreciseNumber notation, we have to know something about precision of seed too and perhaps choose window as well.
