Abstract
A technique for informing an Internet site operator of potential pharming attacks includes generating pharming alerts based on mismatches between a set of expected IP addresses and IP addresses obtained from DNS servers on the Internet and filtering the generated alerts based on circumstances surrounding the generated pharming alerts. Filtering the alerts blocks less suspect pharming alerts while allowing more suspect ones to pass to the site operator, reducing the rate of false positives and better enabling the operator to focus on alerts that may present actual threats.
