Nov 01, 2015 is the Best single graphics card with cracking speed up to 2,096,000 hashes/sec. Using GPU for Cracking WPA/2 Passwords Being in the scope of the series we will stick to WPA/2 cracking with GPU in this chapter. If you are planning to create a cracking rig for research purposes check out GPU hashcat benchmark table below. We tested hashcat against a lot of GPUs. We found that some old GPU (and cheap) give awesome results, at the cost of more power hungry GPU. In particular, we recommend buying AMD 7950 or R9 280 or better. We found those model very cheap. Hashcat is an open-source password recovery tool which uses CPU and GPU power to crack passwords and supports a number of algorithms – including MD5, SHA-1, SHA-2, and WPA. There are no official. GPU memory access requires to be done on 128bits or more for best performance and if possible all memory access shall be avoided. GPU shall use as most as possible registers instead of shared memory. Lot of other hints to found specific to each constraint. Change Log GPUmd5crack v0.2.3 changes. Jun 26, 2020 This video shows how a GPU accelerated hash cracking is superior to CPU based cracking.

Story

Since lot of time I like cryptography and all things aroundcracking/hacking challenge. It is why I have thought about a newchallenge: To crack MD5 as fast as possible using combination of CPUand GPU power (with the help of my GeForce 8800GT and CUDA API).
The development of a MD5 brute force hash cracker using GPU (NvidiaGraphic Processor) is very challenging:

  1. GPU have no easy debug facilities (no breakpoint, no printf... except on linux), and only possible things is to write test in GPUmemory and afterthe test to transfer the result to CPU memory and check it by hand.
  2. GPU programming is very different from CPU programming, onGPU all is executed in parallel and algorithm must be adapted.
  3. GPU hate branch and conditions and that cost lot of time,it is why branch must be avoided.
  4. GPU memory access requires to be done on128bits or more for best performance and if possible allmemory access shall be avoided.
  5. GPU shall use as most as possible registers instead ofshared memory.
  6. Lot of other hints to found specific to each constraint.

Change Log

GPU_md5_crackv0.2.3 changes:
  • This newversion is a special edition for BackTrack4, thanks to OffensiveSecurity Team for their support and help.
    To install GPU md5 Crack on BackTrack 4 do following steps:
    1) Download BackTrack 4 latest version and burn it on a DVD and launchit.
    2)     Launch following commands fromthe shell as root (internet access is required):
    apt-get update
    apt-get install gpu-md5-crack
    3) Now gpu-md5-crackv0.2.3 is ready to use(test it with benchmark):
    ./gpu_md5_crack_0.2.3 -b
  • First versioncommand line only, for Linux and Windows.
  • Add unifiedoptions and multiple charset selection:
    [0-9], [a-z], [a-z0-9], [A-Z], [A-Z0-9], [A-Za-z],[A-Za-z0-9], All Printables.
  • Add benchmarkoption (-b).
  • Add cudadevice choice (-d), to launch multiple instance on different cudadevice for basic multi GPU support.
  • Clarifiedrealtime displayed informations.
  • Cleanupunused header and source code(cutil is no more used ...).
  • Official LGPLv3.0 version see lgpl-3.0.txt.

GPU_md5_crackv0.2 changes:
  • Optimized CPUand GPU code to obtain the fastest possible MD5 brute force crackerusing CPU and GPU combination.Thisversion is highly optimized for Geforce 8800GT or more (GPU code hasbeen optimized with best possible assembly code).
    MD5 GPU brute force speed exceed 200 millions MD5 hash/second (defaultcharset [a-z,0-9]). (Configuration: GeForce 8800GT and Core2Duo E6750using one core)

Plans for the future

  • A new version for 'FPGA' PicoComputing Cards, and maybe anhybrid version CPU/GPU/PICO Card.
  • More optimized algorithm to achieve 300 millions MD5 hash /second.
  • To support combination of multi GPU using multi threadinstead of launching multiple instance in shell.
  • Network-distributed version if enough feedback.
  • Windows/Linux version with Qt Cross Platform GUI (insteadof MFC) if enough feedback.

FreewareIf I have enough feed back/donation I plan also to support othercryptographic algorithm like NTLM, AES-128, SHA-1, RIPEMD-128,RIPEMD160 ...

We all know we can use aircrack-ng to run a wordlist attack to crack WPA/WPA2, in this article I’m going to show you how to do the same using a tool called HashCat, and compare its speed with aircrack-ng.

The advantage of using HashCat is unlike aircrack-ng which uses the CPU to crack the key, HashCat uses the GPU, this makes the cracking process MUCH faster (results below).

Installing & using Hashcat

  1. First you need to download Hashcat from https://hashcat.net/hashcat/
  2. Navigate to the location where you downloaded it, and unzip it, personally I like to use 7zip.
  3. Open the Command Prompt (go to windows search and type cmd).
  4. Navigate to your Hashcat folder where it’s unzipped.
  5. Type hashcat32.exe or hashcat64.exe depending on the architecture of your CPU.
  6. In order to use the GPU, you need to get its id using the following command

mine is #3. Then you need to use the hash type which is 2500 for WPA, I do recommend using

to get familiar with the tool.

To specify device use the -d argument and the number of your GPU.
The command should look like this in end

Example:

Wpa Cracking Tool

Where Handshake.hccapx is my handshake file, and eithdigit.txt is my wordlist, you need to convert cap file to hccapx using https://hashcat.net/cap2hccapx/

Test1: Using HashCat, with Asus GTX 1080 OC edition which has GPU Boost Clock with 1936 MHz, total GB ram of 8 Gigabytes, and Cuda cores 2560.
CUDA = Computing performance Boost Clock = Increases the Clock speed.

Cracking Wpa Wpa2 Psk

Hashcat took 4 mins, 45secs to reach the end of the wordlist and crack the handshake with a wordlist of 100,000,000 passwords.

Aircrack

Test 2:Using Aircrack-ng on Kali installed as main operating system with is i7-7700k CPU – base clock of 4.20, turbo clock 4.50Ghz with 4 cores and 8 threads, it would take 4 hours 22 minutes 14 seconds try all the passwords in the wordlist.

Test 3: Kali installed as a virtual machine, in this case it would take 11 hours, 31 minutes and 40 seconds to try all passwords in the wordlist!
