Is it difficult to find data that SHA256 hash is 256bits of zero ?

You can try a SAT solver. Express the data block and expected output as a huge combinatorial expression and use that as input.
If you can find an algorithm that can reverse an arbitrary hash algorithm in polynomial time, you win USD $1000000.
(Why they didn't they make it $1048576...)
