Is my piston cracked?

I have a KTM EXC 250 2011 with 370h on it. The previous owner guaranteed me the service was done 70h ago, so i removed the pipe and had a look at the piston. I am not sure if this is bad or okay. Besides the black marks on it, are there also some cracks forming? I cant see any obvious scratch marks on the piston or the cylinder wall.

What do you guys think, should i replace it asap?
