Abstract
A system is configured to analyze large volumes of sample emails from past spam campaigns to identify homogeneous features, as well as systematically heterogeneous features, which spam originators fail to obfuscate. By extracting origin-referencing features therefrom, the system predicts that spam originators will mass-acquire domain names at certain registrars for the purpose of future spam floods, and repeatedly and periodically analyzes domain name records on an automated basis to identify domain names which will imminently be utilized as spam origins. Since it may be necessary to block tens of thousands of domains preemptively to avert spam floods, performance of such large-scale analysis by a computing system allows spam origins to be predicted on a timely basis within a day of spam floods being deployed, and domain lists to be generated and configured responsively in time to prevent the spam floods.
