    Bully is a new implementation of the WPS brute force attack, written in C. It is conceptually identical to other programs, in that it exploits the (now well known) design flaw in the WPS specification. It has several advantages over the original reaver code. These include fewer dependencies, improved memory and cpu performance, correct handling of endianness, and a more robust set of options. It runs on Linux, and was specifically developed to run on embedded Linux systems (OpenWrt, etc) regardless of architecture.
    Bully provides several improvements in the detection and handling of anomalous scenarios. It has been tested against access points from numerous vendors, and with differing configurations, with much success.

    Bully requires libpcap and libssl. It uses WPS functionality written by Jouni Malinen; that source code is included in this repro for simplicity, as are libcrypto and several other sources that provide needed functionality.
    Because Bully stores randomized pins and session data in normal files, there is no need for any database functionality.

    Bully can be built and installed by running:
    ~/bully$ cd src
    ~/bully/src$ make
    ~/bully/src$ sudo make install


    A Makefile tested in Kamikaze r18801 (2.6.26) is provided in the repository root directory. Porting to Backfire or another OpenWrt variant should be fairly straightforward.
    Assuming you have ~/kamikaze as your openwrt directory and ~/bully for bully, the following steps should get you up and running:
    cd ~/kamikaze
    mkdir package/bully
    cp -rf ~/bully/* ~/kamikaze/package/bully
    make menuconfig

    Navigate to Network-->wireless and select bully (module or built-in), exit and save. If you elected to build as a package, type
    make package/bully/{clean,compile} V=99
    scp bin/packages/<arch>/bully_1.1-1_<arch>.ipk root@<router-ip>/tmp
    ssh root@<router-ip>

    enter router password,
    opkg install /tmp/bully*ipk

    If you chose to build bully into your firmware, make and install it as you normally would.

    Ensure that you are root, and are using wireless hardware that is capable of injection with a monitor mode interface.

    -c, --channel N[,N...]

    Channel number, or comma separated list of channels to hop on. Some AP's will switch
    channels periodically. This option allows bully to reacquire an AP and continue an attack
    without intervention. Note that using channel hopping will typically slow an attack,
    especially when the AP's signal is weak, because time is spent scanning channels instead
    of testing pins. If no channel is provided, bully will hop on all channels.

    -i, --index N

    This is the index of the starting pin number in the randomized pin file. This option is
    not valid when running bully in sequential pin search mode. This is typically handled
    for you automatically, i.e. an interrupted session will resume after the last pin that
    was successfully tested. Note that when less than 7 digits (8 digits if -B is active) are
    given, zeroes are padded on the left.

    -l, --lockwait N

    Number of seconds to wait when an AP locks WPS. Most AP's will lock out for 5 minutes, so
    the default value is 43 seconds. This will cause bully to sleep 7 times during a lockout
    period for a total of 301 seconds.

    -o, --output file

    By default, messages are printed to the standard output. Use this option to send output
    to the specified file instead.

    -p, --pin N

    This is the starting pin number. Use of this option results in a sequential pin search
    starting at the given pin. This is typically handled for you automatically, i.e. an
    interrupted session will resume after the last pin that was successfully tested. Note
    that when less than 7 digits (8 digits if -B is active) are given, zeroes are padded on
    the left.

    -s, --source macaddr

    The source MAC address to embed in packets sent to the AP. Not all wireless cards can be
    used to spoof the source MAC address like this, but the option is provided for chipsets
    that allow it. When not provided, the wireless interface is probed to retrieve the MAC.

    -v, --verbosity N

    Verbosity level. 1 is the quietest, displaying only unrecoverable error information. Level
    3 displays the most information, and is best used to determine exactly what is happening
    during a session.

    -w, --workdir path

    Working directory, where randomized pins and session files are stored. Session files are
    created in this directory based on the BSSID of the access point. Only one set of randomized
    pins is created, and is used for all sessions. If you want to regenerate the pin file, simply
    delete it from this directory; however incomplete runs that used the deleted file will not
    be restartable. The default directory is ~/.bully/

    -5, --5ghz

    Use 5 GHz (a/n) channels instead of 2.54 GHz (b/g) channels. Untested.

    -B, --bruteforce

    Bruteforce the WPS pin checksum digit rather than calculating it according to the WPS
    specification. Some AP's use a non-compliant checksum in an attempt to evade attacks from
    compliant software. Use of this option can result in a ten-fold increase in the time it
    takes to discover the second portion of the pin, and should only be used when necessary.

    -F, --force

    In certain scenarios bully will print a warning message and exit. This typically indicates that
    it is being used in a manner that is questionable for most users. Advanced users and developers
    can force continuance with this option.

    -S, --sequential

    By default, pins are randomized. This options allows pins to be tested sequentially.

    -T, --test

    Test mode. No packets are injected. Can be used to validate arguments, determine if an
    access point is visible and has WPS enabled, generate a randomized pin file, or create a
    session file for the access point.

    -a, --acktime N

    Deprecated. Packet timings are throttled automatically. Will be removed in future revision.

    -r, --retries N

    How many times do we resend packets when they aren't acknowledged? Default is 3. The idea is to
    make a best effort to ensure the AP receives every packet we send, rather than have transactions
    fail and restart due to a missed packet.

    -m, --m13time N

    Deprecated. Packet timings are throttled automatically. Will be removed in future revision.

    -t, --timeout N

    Deprecated. Packet timings are throttled automatically. Will be removed in future revision.

    -1, --pin1delay M[,N]

    Delay M seconds for every Nth NACK at M5. The default is 0,1 (no delay). Some access points
    get overwhelmed by too many successive WPS transactions, and can even crash if we don't dial
    things back a bit. This is the delay period to use during the first half of the pin.

    -2, --pin2delay M[,N]

    Delay M seconds for every Nth NACK at M7. The default is 0,1 (no delay). Some access points
    handle transactions through M4 easily, only to fall down on too many successive M6 messages.
    This is the delay period to use during the second half of the pin.

    -A, --noacks

    Turn off acknowledgement processing for all sent packets. Useful if you are sure the AP is
    receiving packets even though bully can't see acknowledgements. You might need this for a USB
    wifi adapter that processes acknowledgements and drops them before libpcap ever sees them.

    -C, --nocheck

    Turn off frame check sequence processing. We can improve performance somewhat by making the
    dubious assumption that all packets we receive are valid. See also --nofcs below.

    -D, --detectlock

    Certain access points do not indicate that they have locked WPS in their beacon IE tags, but
    summarily ignore all WPS transactions for a period of time. With this option, we can detect the
    condition and sleep for --lockdelay seconds before resuming. In the interests of remaining
    undetected, there is no point in broadcasting 5 minutes worth of unanswered EAP START messages.

    -E, --eapfail

    Send EAP FAIL messages after each transaction. Some AP's get confused when they don't see this.

    -L, --lockignore

    Ignore WPS lock conditions reported in beacon information elements (don't sleep).

    -M, --m57nack

    Treat M5 and M7 timeouts as NACK's, for those access points that don't send them but instead
    drop the transaction. When using this option you will probably want to increase the --timeout
    value, so that bully doesn't incorrectly assume a pin is incorrect due to a delayed message.

    -N, --nofcs

    Some wireless hardware will have done the work of checking and stripping the FCS from packets
    already. Bully usually detects this and adjusts accordingly, but the option is here if you need
    to force it.

    -P, --probe

    Bully uses beacons to examine the WPS state of an access point. For nonbeaconing AP's, send
    directed probe requests and use the resulting probe responses instead. Requires --essid.

    -R, --radiotap

    Assume radiotap headers are present in received packets. This is useful in cases where presence
    of radiotap headers is incorrectly reported or detected.

    -Z, --suppress

    Suppress automatic timimg algorithm and instead use default timings for received packets. NOT

    -W, --windows7

    Masquerade as a Windows 7 registrar.

    -V, --version

    Print version information to standard output and exit.

    -h, --help

    Display onscreen help.
