Apple devices were most prevalent at 43.3 percent of all devices (28.4 percent alone for iOS iPad and iPhone, with another 14.9 percent running OS X). Linux users composed 35 percent of the total, while Windows users represented 21.8 percent. While the majority of attendees used the Black Hat PSK network, almost 200 attendees utilized the PEAP/EAP-TLS “secured” network. Aruba captured a huge amount of security events, the most interesting of which were IP spoofing, AP spoofing, Power save DoS attacks and Block ACK attacks. Talk about a hostile environment.
