DNS rebinding - Definition from the Hotspot Shield Glossary

DNS Rebinding is a form of digital attack that involves taking control of a users router. The attack uses JavaScript to gain control of the route - In a simple example, a user may visit the attackers website believing it to be authentic, if the user enters a password anywhere on the site, in particular a default password, a piece of JavaScript code will then use this password to altar the users routing device thus gaining access to it.

From here the attacker will be able to control the users internet communications by administrating the router remotely. With access to the users internet communications, the attacker could find out sensitive information or use the internet connection to send spam or cause disruption. Many common routers such as Linksys and D-Link can fall prey to this attack, as can any device that uses a default password.
