Introduction
If a PPTP service has been detected, as part of the protocol the software (and/or hardware) vendor is meant to disclose this information. Generally the server hostname is also revealed, which may aid in an attack. Method There are many ways to determine this, but a simple scenario would be to create a new "dial-up" connection within Windows with a connection type of VPN -> PPTP and connect whilst running a Wireshark packet capture. By following the captured stream within Wireshark and looking at the protocol dissector, the vendor and hostname will be disclosed. Comments are closed.
