Use a Linksys Router? You’ve Got Security Problems

One of the bigger security-related stories over the past week concerns a vulnerability in WiFi Protected Setup (WPS). WPS is designed to be an easy way for inexperienced users to set up a secure network, using methods such as inputing a PIN from your router into your computer or other device. The problem is that the PIN, which is 8 digits long, is susceptible to brute force attacks. In fact, a free tool named Reaver can crack that PIN in just a few hours. This vulnerability exists regardless of the kind of security you’re using on your network, so even WPA2 is at risk. This means that the kid next door could get Reaver running, go off and watch a movie, and a few hours later he is in your network. The solution? Turn off WPS. Unfortunately, you can’t do this with modern Linksys routers.

Wi-Fi is Radiation Too

According to a Dutch study, our beloved Wi-Fi — the stuff that large populations of the planet now use in their homes, their workplaces, where they shop, where they drink coffee, and pretty much everywhere else they go — may be killing our trees. Or at least contributing to it. The researchers of Wageningen University say that more analysis is required to reach a solid conclusion on the matter, but so far, it looks like the particular radiation that is Wi-Fi is not at all interested in becoming a tree-hugger.

Blacksheep Protects You From WiFi Hackers – Sort Of

By now, you’ve probably heard of Firesheep, the Firefox plugin that makes it trivial for someone on an unsecured WiFi network to hack user login info for many social networks and email services.  Yesterday, ZScaler Security released BlackSheep, a Firefox plugin to alert you if someone is using Firesheep on your network.  This is promising, but can also lull you into a false sense of security.  Here’s how you can really protect yourself over WiFi.
