Chances are there is not anything permanent since the information on that game appears to be saved server side. At best, there may be some mods or client side alterations that would provide temporary boosts that could get you banned. I would recommend just playing the game as pioneering through Google may find you some results but then you would have to sift through them all to see which ones are legit or which ones will make you become a victim of a phishing attack since it appears they have had issues with that recently. Anything someone has exploited server side would not be made public and once the exploit is found, it would be dealt with and servers rolled back as necessary.

In short, your best bet is to just play the game and reap the rewards the good old fashioned way.
