![]() The true identity may be either in the form or simply user. Actually Im doing it with my laptop and my AP to test my WLAN security. But where in this wireshark capture should I look for the MAC Adress from the station who sends. If the PEAP/TTLS server is also authenticating the user, it now knows the user’s identity and proceeds with the authentication method being protected by the TLS tunnel. In order to do an injection test, first start Wireshark and the filter expression (wlan.bssid. Alternatively, the PEAP/TTLS server may forward a new RADIUS request to the user’s home RADIUS server. The -0 option is used to choose a deauthentication attack. ![]() This new RADIUS request has the PEAP or TTLS protocol stripped out. If the protected authentication method is EAP, the inner EAP messages are transmitted to the home RADIUS server without the EAP-PEAP or EAP-TTLS wrapper. Deauthentication Frame Station or AP can send a Deauthentication Frame when all communications are terminated (When disassociated, still a station can be authenticated to the cell). ![]() The User-Name attribute of the outgoing RADIUS message contains the user’s true identity – not the anonymous identity from the User-Name attribute of the incoming RADIUS request. Deauthentication frame format is as shown below. It is subtype 12 (0x0c) management frame (type 0) & you can filter it using below wireshark filter. If the protected authentication method is PAP or CHAP (supported only by TTLS), the User-Name and other authentication attributes recovered from the TLS payload are placed in the outgoing RADIUS message in place of the anonymous User-Name and TTLS EAP-Message attributes included in the incoming RADIUS request. ![]()
