What to do if someone steels my art project before I could release it?

Well thing is I suspect it I am not sure (I have my reasons) if I am wronge that's ok but if I am right what to do then. It's better to be wrong then to be negligent. Well this is a very thought out and well place project and done a lot of research and work over a year on this.. Now that it is completed my gpu got fried, and I have to plan something out. But I have suspicion someone have stole my data and they also might have seen my research so they what my plan was. Lets put it this way I have a hacker problem, I can be wrong about my suspicion, but I do or did have hacking issues more couple of times, enough issue that I am having concerns. Now I can be wrong but just in case I want to protect my self. What to do.. I also ask you to , if you can, share word around. The attacted image is the test render I have done in blender cycles. And that it should be publish or post under the name kiraz aksoy. And these accout should be assosiate with gmwor or Umar Güç. If not that is a theif
