About the Talk
WPA2 is vulnerable under certain conditions. This
limitation, though known to the designers of WPA2, is not
well understood or appreciated by WiFi users.
In this talk, I am going to show that exploits are possible
using off the shelf tools with minor modifications.

Background
WEP, the one and only security configuration present in the original 802.11
standard, was cracked in 2001. Since then several attacks on WEP have been
published and demonstrated
Nowadays most WLANs are secured with a much better and robust security
protocol called WPA2 .
Interestingly, WPA2 is also being used to
secure Guest WiFi, Municipal WiFi (e.g.
GoogleWiFi Secure) and Public WiFi (e.g. T-
Mobile or AT&T WiFi Hotspot) networks.

Is WPA2 safe to be used in WiFi networks?
