Segway Subdomain Takeover

During our research on the Segways’ domain space, we found a subdomain pointing to a third-party domain “pending for deletion” by its owner. Using a domain monitoring and backorder service, as soon as the third-party domain became available we got control over Segway’s subdomain.

According to responsible disclosure best practices, we provided Segway a detailed security advisory. This article is published after the security issue has been (silently) fixed by Segway.
