Some may have missed the news of this. A new(er) exploit was demonstrated involving many modem/routers.
It would be a good idea to make sure that:
1. Your login to your router has been changed from default.
2. Don't complain if your ISP has changed your password if you left it as Admin... They did (X69) this in a secure way and sent you a letter.
3. For at least a while, it would be better if you didn't have login/password saved on your regular browser.
4. Get an account on OpenDNS and block rebinds. Most us use OpenDNS anyway but just with a generic account. Set up DNS on the computer rather than the router - because it's less easily crashed.
5. Realize that this is a good thing. I looked very closely at replies to the vulnerability on the forums of third party firmware distributors. I may well change because a sensible and cautious approach with a demo impresses me far more than bluster.
Number 1 - should just be common sense.
Number 2 - Your ISP has NO business being in your system! Even if you haven't changed the default login/password. Instead they should perhaps suspend your service till the issue is corrected, but they should not be in your equipment.
