Simple Dictionary Test - salty - 05-20-2020

Hi,

I'm trying out a simple dictionary attack test. I have an Ethereum wallet I just created with Mist. I used that John the ripper python script to get the hash and put it in hash3.txt. I have the password followed by a newline in guesses.txt.  I run this command:

Code:
hashcat -m 15700 hash3.txt guesses.txt

And it appears to load the dictionary but doesn't seem to succeed. Does anyone have any suggestions?

Code:
hashcat (v5.1.0) starting...

RE: Simple Dictionary Test - philsmd - 05-20-2020

It's in your output:
Code:
Skipping unstable hash-mode 15700 for this device.

It's literally saying that there is a driver problem with your specific device (Apple driver for AMD GPU and Apple driver for Intel GPU)... You could try to test with your CPU with --opencl-device-types 1

or maybe even better, try to test with a more performant (and not that broken, in terms of OpenCL driver support) GPU e.g. a windows (or even ubuntu linux) system with a modern NVIDIA GPU. but also note that scrypt is most of the time (depends of course on the make/model of the hardware and the amount of hardware) faster on modern CPU. so a modern i9 processor on linux/windows etc would probably be even better

There is little we can do here if the driver doesn't work (but the same code works witch each and every other driver/device/operating system etc)

RE: Simple Dictionary Test - salty - 05-22-2020

Thanks @philsmd. It doesn't say anything about Device #1 so I assumed that it could work on the CPU since devices 2 and 3 are graphics.

RE: Simple Dictionary Test - salty - 05-22-2020

When I pass the --opencl-device-types 1 flag, it skips the cpu and of course uses the graphics cards. This makes me think that there is something else going on.

hashcat -m 15700 hash3.txt guesses.txt --opencl-device-types 1

RE: Simple Dictionary Test - philsmd - 05-22-2020

did you try to test with the beta version from https://hashcat.net/beta/

RE: Simple Dictionary Test - salty - 05-22-2020

Thanks! It looks like there is a linux binary and windows executable in there. I'm not seeing a binary for macOS. I will build from master on GitHub and try it out.

RE: Simple Dictionary Test - salty - 05-22-2020

For the latest if any macOs users are curious
Code:
brew uninstall hashcat
brew install hashcat --HEAD

Success!

hashcat -m 15700 hash3.txt guesses.txt --opencl-device-types 1 --show

Where is it storing the result so that --show is required?

For other newbs. I cleared my console too quickly and wanted to run again to see the results. You can run with --potfile-disable to get it to run through the process again: hashcat -m 15700 hash3.txt guesses.txt --opencl-device-types 1 --potfile-disable
