Sounds like this can be fixed through a config change: The White Plains, N.Y.-based company is working with the FBI to investigate the attack, and declined to give more specific details. Vixie did say that tracking the attacker should not be as difficult as February's denial-of-service attacks had been. "Technically, there is cause for hope, where in the (denial of service) case their was no cause for hope," he said. This attacker seemed a bit more skilled than the cybervandals who flooded eight major Web sites in February, Vixie added. "I would bet that this was someone with a little more experience than the last batch." Vixie said that specific attack could not succeed again. "We plugged the hole that has allowed it to happen," he said.
