We love our macs because they aren't very vulnerable to viruses and such. But there is a fairly new kind of attack that targets one's router. All one needs to do is visit a web page or view an image with a nefarious URL. No password is needed. No software gets installed on your computer. In fact, the vulnerability isn't on your computer. The router, once compromised, reports the wrong DNS addresses and can lead you to phishing web sites made to look exactly like your familiar bank web site, etc. When you log in, they get your login credentials and your account is compromised. You won't know it until it is too late. Your browser will report the correct domain name. The only way you'd know is if you actually checked the IP address before being compromised. I'm sure everyone here has a ready list of the IP addresses of all their critical web sites... yea, right.

If you use a 2Wire router this could affect you. Even if you don't, you should periodically check to see if there is a firmware update for your router, and update it. It is usually very easy to do and doesn't take long.
