Scrapes the Alexa 500 for intranet.* and internal.* hostnames and finds 162 live split-horizon DNS entries exposing internal IPs. Because intranet logins are the NT domain names that match public email addresses, the listed hosts can be brute-forced directly. RSnake's own follow-up, lost with the comment thread, confirmed seven returning 401.
