Why You Need to Change Your Broadband Router Password
In this article, Sid Stamm, Zulfikar Ramzan, and Markus Jakobsson have developed a clever, and potentially devastating, attack against home routers. If you are using these mentioned routers in your office, it's time to change that default password.
And then the attacker basically owns the victim's web connection.
The main condition for the attack to be successful is that the attacker can guess the router password. This is surprisingly easy, since home routers come with a default password that is uniform and often never changed.
They've written proof of concept code that can successfully carry out the steps of the attack on Linksys, D-Link, and NETGEAR home routers. If users change their home broadband router passwords to something difficult to guess, they are safe from this attack.
Cisco says that 77 of its routers are vulnerable.
