Hashcat not running/detecting CPU at all?

[windowshopr]

I've read through a few forum posts and FAQ's to help make this question as easy to answer as possible, but using a Windows 10 machine here, AMD CPU, with a VERY old NVidia GPU 610. When I run 

Code:

hashcat64.exe -I

, I get the following output:

Code:

hashcat (v5.1.0) starting...

OpenCL Info:

Platform ID #1
  Vendor  : NVIDIA Corporation
  Name    : NVIDIA CUDA
  Version : OpenCL 1.2 CUDA 9.1.75

  Device ID #1
    Type          : GPU
    Vendor ID      : 32
    Vendor        : NVIDIA Corporation
    Name          : GeForce GT 610
    Version        : OpenCL 1.1 CUDA
    Processor(s)  : 1
    Clock          : 1620
    Memory        : 512/2048 MB allocatable
    OpenCL Version : OpenCL C 1.1
    Driver Version : 388.13

So I don't see my CPU in there at all. When I try to run hashcat with the GPU, it tells me that the CUDA version is too old/I know this GPU is old, I don't want to use the GPU (per se, unless there's a way to update the driver to allow it but I doubt it). I just want to start crackin' on my CPU.

The command I run and output looks like this:

Code:

hashcat64.exe hashes.hash -m 10500 -a 3 -D 1 -w 2 ?l

(The logic I'm going for is, run hashcat on the hashes.hash file, hash-type is PDF 1-5, attack type I want to be just brute force, device should be CPU, workload 2 and lowercase characters. Not sure how to set min and max characters)

Code:

hashcat (v5.1.0) starting...

No devices found/left.

Started: Thu Oct 21 13:57:55 2021
Stopped: Thu Oct 21 13:57:55 2021

So I take out the

Code:

-D 1

part, and get this:

Code:

hashcat (v5.1.0) starting...

The wordlist or mask that you are using is too small.
This means that hashcat cannot use the full parallel power of your device(s).
Unless you supply more work, your cracking speed will drop.
For tips on supplying more work, see: https://hashcat.net/faq/morework

So, the two issues I see here are 1) it's trying to use the only available device, which is giving me that outdated CUDA error, but also 

Code:

The wordlist or mask that you are using is too small.

, even though I'm wanting to use Brute-force only? Any ideas on what I need to do? The FAQ regarding "device not found/left" looks like it only pertains to GPU's and yes, that's probably what I need to invest in, but how can I get it working on my CPU?

UPDATE

I downloaded the Intel® CPU Runtime for OpenCL program from here and installed it:

https://registrationcenter-download.inte....0.616.exe

Now when I run -I my CPU shows up:

Code:

hashcat (v5.1.0) starting...

BUT, now when I run the same

Code:

hashcat64.exe hashes.hash -m 10500 -a 3 -D 1 -w 2 ?l

command, I get the following output:

...and then the program just ends there, I see my command line at the bottom again. I'm wondering if it has something to do with the hashes, I read to not post them here unless asked to, but what else could I be missing? Thanks!

[Snoopy]

please also update your hashcat (where are all these people get these old versions?)
version 5.1 is really old, actual version 6.2.4
get the latest beta https://hashcat.net/beta/

one hash was already cracked and removed
if your hashcat seems to stuck, just press enter in your cmd-window or try adding option for automitic refresh
--status --status-timer=10

second

your mask just consist of one position with ?l
so just 23 possibilities, so all possibilities are checked and hashcat is finisching this attack in what? a second...

@Snoopy worked like a charm! The update got er goin. Thanks!

One (or two) last things, could you point me in the direction of some resources regarding the masks? Like how to structure them so that it's guessing what I need it to? And also on how to set min/max character lengths? Thanks!!!

[Snoopy]

well depends on the language you are trying to crack

you could start with some known plain pw list for your language and feed them to https://github.com/iphelix/pack

there you will get a good overview of mainly used length and some basic masks like

word+year like dog1981

Wicked, thanks a lot!
