"The attacker was well prepared and knew in advance what he was to try to achieve. He seemed to have a list of targets that he knew he wanted to obtain certificates for, was able quickly to generate the CSRs for these certificates and submit the orders to our system so that the certificates would be produced and made available to him."

If they were that prepared why not use a host in a different country?
