On cyber attacks leveraging DNS: where are the numbers?

DNS is a critical infrastructure: it is often leveraged to launch attacks and/or for criminal intents. Recent news further demonstrates that the impact and consequences of such cyber attacks could be extremely serious.

I am looking for public statistics, reports, analysis, etc. that quantify the amount of cyber attacks  that directly or indirectly exploit DNS infrastructure. Any help (links, documents, etc.) would be really appreciated.
