Can't even launch hashcat, dead domain, cached credential - AlexisPERR - 11-17-2023

Hi guys, 

I really delayed requesting your help here cause I'm computer savvy (or thought I was) , but I already spent hours on this and can't even launch a basic hashcat command line.
Here is my story :

1/ I have an old XP laptop, linked to a domain. The domain is dead a long time ago. The laptop is dead. The HDD is ok, but it's a rare 50 PIN IDE connector. I order a special USB case for it.

2/ one month after, I receive the USB case, plug the HDD. I use disk2vhd to make a VM out of it. I start the VM

3/ XP starts. Blue screen of death after blue screen of death. Something about the HAL not compatible with Hyper-V. Grab an XP SP3 iso, manage to repair (by reinstalling over). XP starts to logon, inactivated.

4/ I can log on as local admin, Safe mode, reset the activation for 30 days. install an old integration Services iso. XP kinda work. Cool.

5/ But the thing is, I must log as a domain user to access crypted Outlook files. Its is possible because XP retains the cached domain credentials for that user.  Of course the password is forgotten. I grab mimikatz from Benjamin DELPY and Vincent LE TOUX. Chrome forbid me to download it, because of course.

Here it is ! the hash in plain text

6/ I grab hashcat v6.2.6, launch it on Windows 7

I go to intel website and and install the latest OpenCL for CPU
Intel® CPU Runtime for OpenCL™ Applications with SYCL support

6/ launch again it on Windows 7

seem related to Windows 7

7/ don't like Windows 7 ? ok, I make a VM with latest Windows 11 Pro, 8 GB of RAM, launch

 hashcat --backend-info

8/ What ? The latest version, the latest driver, the latest OS and it still doesn't work ?
Maybe if I try an old version ? Nope :

9/ What is TBB by the way ? Maybe searching in the forums will help. I will register.
 "Please type hashcat latest version number to register"
Isn't it v6.2.6 ?
Nope, doesn't work.

10/ Finally manage to register (how?)
Search for "TBB"
"One or more of your search terms were shorter than the minimum length"

11/ Okay then I search "Cannot load TBB"
"No result"

12/ Really, nobody except me have this problem ? Maybe Google ?
https://www.google.fr/search?q=hashcat+Cannot+load+TBB

"No result"

Guys I am lost. I am going to sleep.

VM's don't usually have direct access to hardware, hence the errors. It's searching for the proper runtimes and configuration for your hardware but you're running in a VM. It will strictly emulate hardware but not actually provide access to it so hashcat is throwing a tonne of errors.

So what OS is running on the PC which is hosting the VM's? If its Windows 7, you should have no problems using that. Once the Hash has been obtained it can be run on mostly any operating system as long as the proper drivers are supported between both the OS and hashcat. In this relation, look at the hashcat homepage for the requirements.

Mmmm never heard about that for the CPU. In fact you shouldn't even be able to tell if you are within a VM or not. The only exception is you can't Hyper-V within Hyper-V.

I searched Google
https://www.google.fr/search?q=OpenCL+CPU+in+a+VM
and all there is is a few discussions from 10 years ago telling it is possible.

I think it is more a matter of compatibility between hashcat version and Intel OpenCL CPU version.
I registered on Intel website, and there they offer the following downloads:

Code:
opencl_runtime_18.1_x64_setup.msi
w_opencl_runtime_p_2021.1.1.191.exe
w_opencl_runtime_p_2021.2.0.616.exe
w_opencl_runtime_p_2021.3.0.3372.exe
w_opencl_runtime_p_2021.4.0.3556.exe
w_opencl_runtime_p_2022.0.2.3692.exe
w_opencl_runtime_p_2022.0.3.3747.exe
w_opencl_runtime_p_2022.1.0.3787.exe
w_opencl_runtime_p_2022.2.0.9553.exe
w_opencl_runtime_p_2022.2.1.19741.exe
w_opencl_runtime_p_2023.1.0.46319.exe
w_opencl_runtime_p_2023.2.0.49500.exe
w_opencl_runtime_p_2024.0.0.49848.exe


I am going to download every hashcat version possible and cross test it with every OpenCL version possible.
Do you have a trusted download for OpenCL version 16 and 17 ?
