So this game is a MMO. Its not exactly a mainstream game, but players will access one server. I dont trust the client so far as that he cannot really cheat in my game or so.
The thing I am really worried about is that someone sends a bad package and this raises an exception on the server(ArrayOutOfBounds, InvalidMemory etc.).
I don't need to worry about really proffesional attackers, but if someone attempts to hack the server and the server crashes, all players will be kicked and this will be really annoying for them.
So my game is a combination of turnbased combat and trading card games for mobile plattforms. How likely is this to be hacked if it reaches 1 million downloads(really optimistic thinking, but for security issues the worst case)?
I think I'll think my networking lib through and check on how it could be hacked and catch those cases. Then it'll hopefully be enough.
