DNS Exploit Loose - Check Your DNS Server

To the 2 or 3 people that read my blog, make sure your DNS is secure. There is an exploit in the wild that can poison DNS settings (steering you to a malicious site instead of your banking site for example). Read this article for more details. There is a link to a DNS checker or better yet, just switch to OpenDNS. I've been using OpenDNS for years now. You should also look into using NoScript if you're running Firefox. It's an addon that only allows Javascript to run from sites on your whitelist. It's a pain in the ass at first because you have to whitelist everything you usually use, but it's one of the best ways to secure yourself from malicious websites (although if your DNS is poisoned, you're out of luck).
