Automated detection, alarming, and removal of subdomain takeovers

Abstract:

Techniques for automated detection and mitigation of subdomain takeovers are described. A method for automated detection and mitigation of subdomain takeovers comprises receiving, by a subdomain manager, a request to monitor one or more resources associated with one or more mapping records, periodically scanning each resource from the one or more resources, receiving a response from at least one resource indicating that the at least one resource does not exist or is invalid, and sending a notification indicating that the at least one resource does not exist or is invalid using a notification service.
