Millions of Home Routers Are Hackable
Julie188 writes "Craig Heffner, a researcher with Maryland-based security consultancy Seismic, plans to release a software tool at the Black Hat conference later this month that he says could be used on about half the existing models of home routers, including most Linksys, Dell, and Verizon FiOS or DSL versions. The tool apparently exploits the routers through DNS rebinding. While this technique has been discussed for 15 years or more, Heffner says, 'It just hasn't been put together like this before.'" Notebooks.com has a list of routers tested and some advice on securing vulnerable routers.
The important info
Heffner tested his attack against 30 router models and found that about half were vulnerable. Here's his chart of which are and aren't subject to attack. ("Successful" in the far right column means that the router was successfully hacked.)
