Backdoor in wireless DSL routers lets attacker reset router, get admin

Quote:
A hacker has found a backdoor to wireless combination router/DSL modems that could allow an attacker to reset the router’s configuration and gain access to the administrative control panel. The attack, confirmed to work on several Linksys and Netgear DSL modems, exploits an open port accessible over the wireless local network.

The backdoor requires that the attacker be on the local network, so this isn’t something that could be used to remotely attack DSL users. However, it could be used to commandeer a wireless access point and allow an attacker to get unfettered access to local network resources. Update: Vanderbeken reports some routers have the backdoor open to the Internet side as well, leaving them vulnerable to remote attack.

Boy oh Boy.
The bad guys create new threats by the hour.

I think I'm safe from such things.

My router and modem are always off when the computers are off.
My computers are off when I'm not using them. No Sleep or Hibernation is used.
My router has both antennas removed and foil put over the connections. Everything that attaches to the computers is hardwired.

What do you think Bill. Will this keep me safe from such a attach?

Well, this particular attack is unlikely, as most require being on the same local network. The other possibility is wirelessly, and I believe would be unlikely as a random occurrence. I'd think a targeted attack would be the only possibility, and most individuals would not be a target. I think you doing what you do also greatly reduces the opportunity for anyone to even try.

I have a wired router just for the NAT. My modem has a standby switch which disconnects from the internet. When I'm not on the PC, either the standby switch is on, or the PC is off. I'm unsure whether a Stealth result from Shields Up also means the router cannot be seen by the internet, since it scans only the system's first 1056 ports?
