French hacker Eloi Vanderbeken hacked into his Netgear router over the Christmas break. He found a service listening on port 32764 that could be instructed to dump the routers configution and admin username and password. A patch closed the listening port and with it the backdoor was reactivated by default. It means you can re-renable it by sending the router a so-called magic ethernet packet which acts as a signal, rather than carrying data, telling a network card to power up.”]
