Pyrit CUDA:  Release the Kraken!

How To Install Pyrit CUDA on a Mac

We hope that you have not landed here randomly, Pyrit CUDA is not for the faint of heart, But your patience will be rewarded.  Highly rewarded.

CUDA stands for Compute Unified Device Architecture. It uses or unleash the power of your GPU(s) to compute a bit faster things like .... WPA key Recovery.
Pyrit CUDA is not a magic bullet, it's just a much, much bigger caliber.

Why Pyrit CUDA?
On my "Old MBP", Pyrit CUDA is 45% faster than Aircrack-ng without a sweat,  If you have a "New Mac" with a much faster Graphic Card, you can expect 50-200% faster. 
45% means than instead of running for 10hrs, you'll do the job in 5.5hrs,  Some monsters claim 89,000 PMKs/S.  With a little tweak, you can go 300% faster, see example under "tips"

I went to Pyrit after finagling wayyyyy to much with Aircrack-CUDA.  Using Backtrack5 on VMware, Aircrack-CUDA was the straw that broke the camel back: The time needed for the install and fixing the issues was longer than trying Aircrack the regular way.  So, here is Pyrit, native on a Mac.
Pyrit also allows you to create database of pre-computed PMK, also known as Rainbow Tables, and here, it starts to go really fast ... 


How To Install Pyrit CUDA on a Mac, OSX 10.6.8
For OSX 10.7 Lion, almost the same, but read the help first

1)    Click  > About this Mac > More Info > Graphics/Display to check your Card model #
1a)  Verify that you have a CUDA supported graphic card, if not , we're sorry to see you go...
2)     Follow the steps exactly in the order they are mentioned.
3)     You need to have Admin Rights or the Admin Password
4)     You should be Terminal Savvy. If not read the tips at the end first 
5)     You need to type the commands verbatim.  A space too much and you're out ....
6)     You can click on the pictures to enlarge them. It could help....
7)     There is a list of warnings at the end, read them!
8)     Verify that you have verified the verifications


The full install takes about 30~45 min.

Ready?

Download,  in a easily accessible folder the following , do NOT install yet

Nvidia CUDA drivers for Mac:
http://www.nvidia.com/object/mac-driver-archive.html

CUDA SDK    (requires OSX ver. 10.6.7 or higher)
http://developer.nvidia.com/cuda-toolkit-40
Select  "CUDA Toolkit" under Mac OS
For Older Version (10.6.6 and under)

NOTE: 
If you have an "old" Nvidia card, try the "older version" first, you'll save a lot a space. 
the "old version" is half the size of the new one, and you can always upgrade later 


Libnet
http://libdnet.googlecode.com/files/libdnet-1.12.tgz
pylibpcap
http://dfn.dl.sourceforge.net/sourceforge/pylibpcap/pylibpcap-0.6.2.tar.gz  
Scapy
http://www.secdev.org/projects/scapy/files/scapy-latest.tar.gz

You should now,  have something looking like that:

Install  Nvidia Driver for Mac
Click on the DMG, etc ..

This install is going to take few minutes..
While installing....
Take few seconds to click the Like button on our FB page
Thanks


Install  Nvidia CUDA TOOLKIT for Mac
Click on the DMG, etc 

Open Terminal and start the installation of libnet
"Path to"  refers to the path to the file. i.e /Users/MyName/Downloads/
Example:

tar -xzf  /Users/MyName/Downloads/libdnet-1.12.tgz

Install

tar -xzf  “Path to” libdnet-1.12.tgz cd libdnet-1.12 ./configure make sudo make install cd python sudo python setup.py installInstall  Nvidia Driver for Mac, C

Now we install Pylibpcap 

tar -xzf “Path to” pylibpcap-0.6.2.tar.gz cd pylibpcap-0.6.2 sudo python setup.py install

Scapy Install

tar -xzf "Path to" scapy .tar.gz cd scapy sudo python setup.py install

 

Now the prerequisites are done, we can go in the hearth of the subject.
From the Terminal Window, Download Pyrit

svn checkout http://pyrit.googlecode.com/svn/trunk/ pyrit-read-only

Build and install Pyrit

cd pyrit-read-only cd pyrit sudo python setup.py install

Last step, Pyrit CUDA

cd pyrit-read-only cd cpyrit_cuda sudo LDFLAGS=-L/usr/local/cuda/lib python setup.py install

 

Now we need to check if all of that was worth it
Check if Pyrit CUDA is working 

pyrit list_cores

You should see a list of your cores and a list of your GPU(s)
Something like

Once done, let's Benchmark it and see if we can Release The Kraken

pyrit benchmark

*I have installed Pyrit on an old machine, the "good ones" are "reserved" for work. :-)
  Leave a comment either here or on FB with your Config and the Benchmark Results.

GTK, FAQ, RFAQ, TIPS, Help

GTK!  AKA "Good To Know"

Bruteforcing is time consuming, so you need to go as fast as possible, and also AS SMART AS POSSIBLE:   Bruteforcing in blind mode, aka starting @ "00000000" and going all the way up, trying each alphanumerical combination is just a pure waste of your (limited) time, you silly mortal, and your electricity bill will go up a bit.  Go smart, use a statistically sorted Attack Dictionary: Most used password first:  If the password to discover is "password" running an incremental attack will take you few months: The first set of numbers is 100,000,000 long, then for each set of letters, add 110,075,314,176. You have 24 sets, hence 2,641,807,540,224 passwords.  Then repeat with upper cap... then mingle all of that ... a0a0a0a0
Your brain has now stopped perceiving the true value of those numbers.  Mine too.
But that's not it! 
Mr. WPA is a tedious little man:  Each password has 4096 round of hash, salted with the BSSID.  It means in clear that your CPU/GPU will crunch about 1 Megabytes (byte, not bit) of data for each PMK (Pairwise Master Key)  , Each Password is "about" 4 PMK
2500 PMK/second and you'll have 2.44 Gigabytes of data being pushed trough per second...
The first set of numbers, 8ch long, will boils down to about a billion megabytes of data being crunched. 
So, Act like a ninja, and think like Einstein: Go smart!

Tips

If you are here, you should know it:  Don't play too much with the sudo command: it's an unforgiving command.  sudo does not give any warning,  sudo is "Das Terminator" 
Long paths
Avoid typing long path with spaces or weird names:
1) Download in a easily accessible folder
2) Type your command, i.e "tar -xzf" then drag the file from Finder to Terminal; the path will automagically appears correctly.
3) Use the arrow up to call back a previous command
4) copy and paste the command instead of re-typing them:
"cd cpyrit" just looks like "cd pyrit"  ( "C"pyrit )
(The first one that will comment about cd not working will get seriously flamed)

CUDA use 
When using Pyrit CUDA, quit all applications, including Anti-virus, Browser etc, I mean everything: Dropbox, Airport, etc. Anything that use a single %. Kill all processes but the vital ones: The performances will improve significantly.
For the best results, don't even use a screen saver:  quit everything and let the screen go black. Remember? CUDA is using your GPUs.  Following those tips you'll see the performance increasing  significantly:

We are now 279% (Two-hundred-seventy-nine ) faster than Aircrack-ng 1.1 and  600% faster than KisMAC 0.3.3 .  Yes, 600%.  But, that's not it!  Can you go faster than that?

Temperature:
If you crunch for hours, don't forget that  Pyrit CUDA will try to use 100% of your CPUs and 100% of your GPUs: The Temperature is going to go up a bit. If you have a laptop, I'll suggest to elevate it on the four corners and leave at least 1/2 inch of free space under.

Pyrit on OSX Lion 10.7 
"Many people have problems compiling Pyrit on OSX Lion. The version of GCC distributed with the latest XCode no longer supports creating binary code for the PPC-architecture and Python’s setup.py does not know about that; you can get an error message like the following:"

assembler (/usr/bin/../libexec/gcc/darwin/ppc/as or /usr/bin/../local/libexec/gcc/darwin/ppc/as) for architecture ppc not installed

You can solve this situation by forcing GCC to only compile code for the i386- and the x86_64-architecture. To do this, put the following into your .bash_profile:

export ARCHFLAGS=”-arch i386 –arch x86_64”

Basic Command lines
 

pyrit  -h attack_passthrough

The -h option gives a more detailed help on an option, here help on "Attack_Passthrough" -h should be used profusely.

pyrit benchmark

Does a Quick Benchmark

pyrit benchmark_long

Does a long Benchmark

pyrit -r test.pcap -b 00:de:ad:be:ef:00 -i words attack_passthrough

Regular attack on a specific ESSID via Dictionary

pyrit -r test.pcap -b 00:de:ad:c0:de:00 -o passwd.txt attack_batch

  "Pairwise Master Keys that have been computed and stored in the
database previously are taken from there; all other passwords are
translated into their respective Pairwise Master Keys and added to
the database for later re-use. ESSIDs are created automatically in
the database if necessary." 
Note:  .PCAP, .CAP or Dumplogs are the same

Overclocking
You can overclock, but: 
As much as you will be tempted, let me remind you that if you have a laptop, things may get hot.  Really hot!  Even SMCFan Control may not be enough.
Frying your GPU will not be a good thing.  Overclock at your own risk(s)
