WLAN deauthentication attack

Erich_V — Thu, 16 Jan 2020 07:44:28 GMT

Over the festive days, I was playing with some ESP32/ESP8266 microprocessors and found an interesting project for deauther WLAN stations and clients with a small snippet of Code, using the deauthentication mechanism in in 802.11 protocol. Without being authorized by an SSID/AP, I was able to attack my home WLAN and a separated part of the Meraki WLAN in my office.

What scared me most is the fact you can buy prebuilt development boards for cheap money.

Is there any possibility to protect the MR devices from such attacks? I didn't found any related Information about this specific Problem in the documentation.

Only solution would be using 802.11w option, in order to enable management frame protetion.

The problem here is that not all devices support this feature.
