1. A method in a cloud-based proxy service for identifying a target of a denial-of-service (DoS) attack, the method comprising:

  • determining that there is an abnormal flow of traffic being directed to an IP address of the cloud-based proxy service that is indicative of the DoS attack;

    responsive to determining that there are a plurality of domains that resolve to that IP address, identifying the one of the plurality of domains that is the target of the DoS attack, wherein the step of identifying includes performing the following;

    scattering the plurality of domains to resolve to different IP addresses, wherein a result of the scattering is that each of those domains resolves to a different IP address, andidentifying one of those plurality of domains as the target of the DoS attack by determining that there is an abnormally high amount of traffic being directed to the IP address in which that domain resolves.
