WIFI Security

*IEEE
802.11a 5GHz 52Mbps OFDM (ortogonal multiplexing) low distance (hight frequency, lower distance)
802.11b 2,4GHz 5MHz*14channels DSSS (spreaded spectrum) (ch14 only used in Japan)
802.11g 2.4GHz


*Open System Authentication
The only "security" check is the ESSID

*Shared Key authentication

WEP -> CRC32 + RC4 (the same all the communication) -> weak security
WPA -> TKIP + RC4 (different every time)
WPA2-> AES + EAP -> strong security

*Bluetooth attacks
- bluejack send spam anonymously to victyms.
- bluebof exploit overflows in services remotelly.
- bluebug use AT commands on victims cell phone.
