Fingerprinting 802.11 Implementations via Statistical Analysis of the Duration Field
Johnny Cache
The research presented in this paper provides the reader with a set of algorithms and techniques that enable the user to remotely determine what chipset and device driver an 802.11 device is using. The technique outlined is entirely passive, and given the amount of features that are being considered for inclusion into the 802.11 standard, seems quite likely that it will increase in precision as the standard marches forward. The implications of this are far ranging. On one hand, the techniques can be used to implement innovative new features in Wireless Intrusion Detection Systems (WIDS). On the other, they can be used to target link layer device driver attacks with much higher precision.
