Is it possible to steal a source code?

Is it possible to steal a source code just from the creator hosting the game? If so, is there a way to stop it from happening? Because some guy came in, said lol! hax0r! and left. I'm alittle concerned, his name was Dhakkon.

Anyways maybe i'm just over-reacting. But i spent about 5 months on the code and I don't want it stolen.
