Wireless Sniffing Article in June Issue of (In)Secure Magazine
The newest issue of (In)Secure Magazine has been released today. This issue contains an article I’ve written entitled “Using Wireshark to Capture and Analyze Wireless Traffic”.
Article Introduction:
The tricky thing about a wireless network is that you can’t always see what you’re dealing with. In a wireless network, establishing connectivity isn’t as simple as plugging in a cable, physical security isn’t nearly as easy as just keeping unauthorized individuals out of a facility, and troubleshooting even trivial issues can sometimes result in a few expletives being thrown in the general direction of an access point. That being said, it shouldn’t come as a surprise that analyzing packets from a wireless network isn’t as uninvolved as just firing up a packet sniffer and hitting the capture button.
In this article I’m going to talk about the differences between capturing traffic on a wireless network as opposed to a wired network. I’ll show you how to capture some additional wireless packet data that you might not have known was there, and once you know how to capture the right data, I’m going to jump into the particulars of the 802.11 MAC layer, 802.11 frame headers, and the different 802.11 frame types.The goal of this article is to provide you with some important building blocks necessary for properly analyzing wireless communications.
