Abstract
Systems and methods for identifying, in a domain name, n-grams that do not appear in words of a given language, where n is greater than two are disclosed. The disclosed systems and methods may include comparing a value based on a number of the identified n-grams to a threshold and indicating that the domain name is potentially generated by malware in response to the value having a specified relationship with respect to the threshold.
