Without knowing for sure, I think you could just block port 8333. The individual miners could surely be DDoS, if you know their IP.
I wonder if it's possible to just generate junk transactions and throw them at miners.

Junk transactions could stop a few nodes but all transactions are verified locally on nodes and won't be broadcast if they turn out to be junk.
