Detecting Wireless LAN MAC Address Spoofing
Description: An attacker wishing to disrupt a wireless network has a wide arsenal available to them. Many of
these tools rely on using a faked MAC address, masquerading as an authorized wireless access
point or as an authorized client. Using these tools, an attacker can launch denial of service
attacks, bypass access control mechanisms, or falsely advertise services to wireless clients.
This presents unique opportunities for attacks against wireless networks that are difficult to
detect, since the attacker can present himself as an authorized client by using an altered MAC
address. As nearly all wireless NICs permit changing their MAC address to an arbitrary value –
through vendor-supplied drivers, open-source drivers or various application programming
frameworks – it is trivial for an attacker to wreak havoc on a target wireless LAN.
This paper describes some of the techniques attackers utilize to disrupt wireless networks
through MAC address spoofing, demonstrated with captured traffic that was generated by the
AirJack, FakeAP and Wellenreiter tools. Through the analysis of these traces, the author
identifies techniques that can be employed to detect applications that are using spoofed MAC
addresses. With this information, wireless equipment manufacturers could implement anomalybased
intrusion detection systems capable of identifying MAC address spoofing to alert
administrators of attacks against their networks.
