Countering rogues in wireless networks

Wired networks are prone to the same attacks as wireless ones, including sniffing, spoofing and man-in-the-middle attacks (MITM). In this paper we show how wireless networks are particularly vulnerable to a simple MITM that can make even rudimentary Web surfing dangerous. We describe how we performed the attack and its ramifications. We argue why it is essential to have a VPN tunnel from the client to some trusted host (not access point) in order to avoid being compromised.
