Wireless Without Worries (WWW) - Six (6) WI-Fi Myths1/1/2009 8:01:00 PMWi-Fi Myths and Truths
Over the years I've heard a number of misconceptions about wireless networking. I'm going to deal with the common public misunderstandings about wireless hacking and security in this article. Now the myths that are commonly heard from non-security professionals.
1. Myth: “It takes a lot of expensive equipment to hack wireless networks.”
Truth: The truth is all it takes is an
old wireless laptop. The first laptop I used to test and break into our wireless networks is now 10 years old and it still has more than enough power to break into any wireless network.
2. Myth: “It takes a lot of expensive software to hack into wireless networks.”
Truth: The truth is the software is freely downloaded from the
Internet. All you have to do is search for terms like “hacking wifi” on Google and you'll find all the free software and entire communities built around those hacking tools.
3. Myth: “You have to be super smart to be able to break into wireless networks.”
Truth: There is a certain element of truth in that, but it's a half-truth. The truth is network security is very complicated and you do have to understand it at a very deep technical level in order to understand how to break wireless networking. And the hackers that make the tools have learned all the complications of wireless security. When they create a tool they make the tool easy to use, so someone without any technical knowledge can use them. And they thrive on helping others use their tools to break into wireless networks. They have complete online communities built around helping others break wireless networks.
With these three myths cleared up, let me draw you a picture of a typical hacker. Imagine a teenager who's mom or dad has an old laptop that they replaced several years ago. The old laptop is just stored in the closet and the bored teenager takes it and installs the free software and begins breaking into his neighbor's wireless networks. The parents think it's great because they don't really know what he's doing, all they see is little Johny is starting to take an interest in something other than the X-box and skateboarding – something that may lead to a career. They just don't realize that particular career may be one at the state pen.
4. Myth: “I set a password on my wireless network, so I'm safe.”
Truth: The truth is all the security that comes on wireless routers can be broken with the freely downloaded tools so having a password set only gives a false sense of security. Google and read more on WEP, WPA, and WPA2.
5. Myth: “The hotel/café/shop where I get on the wireless network gave me a password, so I'm safe.”
Truth: Again, not only can the security be broken, but that same password is given to anyone else that uses that wifi network, so a hacker doesn't even have to try to break into it. With the password they can see everything you do online without having to first break the security.
6. Myth: “I have McAfee, Norton, Windows firewall, or some other Internet security or anti-virus program installed, so I'm safe.”
Truth: Those programs are good for what they do, but they don't actually protect your wireless use. There are even a number of wireless “security” programs that I've seen that don't actually secure your wireless data, they just prevent hackers from connecting to your computer over the wireless network. The weakness with all of these programs is they only secure the data that is on your computer, but they have no way of protecting that information when your computer is transmitting it on a wireless network. Yes, you do need a good firewall and anti-virus, but you also need to protect your information that is sent out over the wireless networks you use. If you think the security program you are using may not protect your wireless data and want me to check it out, email me the name of the product and website and I'll let you know exactly what it does and doesn't do.
