Is there anyone that, with full access to the machine/kernel, has managed to predict the output of random/urandom? I know that a PRNG is predictable if you know all the input variables, and the code for it is publicly available, but has anybody in practice been able to exploit that? EDIT: that's an honest question. I'd like to read a paper about that.
