Vulnerability in VPN networks allow knowing IP address of the user




A company Perfect Privacy, specialized in the field of protection and VPN virtual private networks, for security vulnerability in VPN networks allow access to the user’s IBM IP address.

The company said the new loophole, known as “Port Fail” exist in all servers companies that offer the possibility of re-port Port Forwarding conversion without the use of a layer of protection.

The hacker can fool any user based on the same virtual private network service and convert it relates to a new port and get the mail using his real IP address, and thus VPN, which is mainly used to hide the identity of the user fails to work.

The company reviewed the steps to exploit the gap, where the hacker needs beginning to use the same VPN service used by the victim, then you must obtain e-mail address fake; this can be through force him to visit a particular link, or follow-up contact with one of the servers torrent Torrent or a chat servers such as IRC . Finally, the call is transferred to a bogus outlet port is controlled by the hacker gets to the real address of the victim and therefore to be identified with ease.

The vulnerability can be closed through the use of more than one level of electronic addresses within VPN services, or by installing a firewall Firewall prevents any real connection is via the IP address of the user.

Perfect Privacy and conducted tests on the company nine VPN service providers famous, found that five of which are unsecured from this gap and can attack their users with ease.

And use virtual private networks VPN to hide the fact the user’s identity and e-mail address change through the conversion of its connection across a group of servers before reaching the desired location, and thus adds a layer to protect the user connection.
