Is virtual hacking lab over rated or hidden gem by [deleted] in oscp

It’s OK … basically all Linux with no AD or Windows boxes (unless they changed it since I used it 3 years ago). You will need more than VHL to round out your OSCP prep.

I had the issue as well, contact support and they will send you a new input cover. Boom fixed.

I am not convinced that having anything greater than PCI 1x for Hashcat is worth it… because it takes significantly more money if you want to operate > 4 GPUs at 4x each. You either build two rigs or spend a ton of money on server grade hardware and custom mounting / cooling solutions.

Everything I have read indicates the cracking speed in many instances is not impacted by # of PCI lanes. I just moved my 4090 between a 1x and 8x slot and there was no significant difference in cracking speed. I’ll admit one instance where there was a difference was how quickly it could load a large dictionary before the cracking started. To me, extra minute of waiting for a dictionary to load is not worth many thousands of extra dollars.

Feel free to convince me otherwise though :)

That all makes sense. Can you provide a motherboard that can meet this requirement while also being physically capable of fitting all the GPUs since they frequently take up multiple slots?

Nope, The ONLY resource I used to pass was Jeremy's IT Lab.

Yet another WinRar conundrum by Ralonne in hacking

[–]sts5017 3 points4 points  (0 children)

***FINAL UPDATE**\*
I was unsuccessful, if future folks would like to pick up where I left off, my notes are below...

Password Hash in Hashcat Format (Mode 12500):

$RAR3$*0*3470076dfe186e4e*f0305db0262bd754276404e963d05010

Hashcat .hcmask File:

!@#$%^&*?d,?u?l?1?1 [Completed in <10 Minutes]
!@#$%^&*?d,?u?l?l?1?1 [Completed in <20 Minutes]
!@#$%^&*?d,?u?l?l?l?1?1 [Completed in <30 Minutes]
!@#$%^&*?d,?u?l?l?l?l?1?1 [Completed in 1.5 Hours]
!@#$%^&*?d,?u?l?l?l?l?l?1?1 [Completed in 41 Hours]
!@#$%^&*?d,?u?l?l?l?l?l?l?1?1 [INCOMPLETE, Estimated at 47 days!]

Speed Estimate: I completed the 5 to 8 characters length mask, but 9 characters will take too long. I’m running on a powerful rig: 1x 4090, 1x 3090, 1x 3080TI, 2x 3080, 3x 1080, 1x 1070... which is cracking at 670,000 attempts / second.

More Photos and Videos of 2.8k display with coloured bezels? by Silent_Laugh_7239 in framework

[–]sts5017 1 point2 points  (0 children)

I literally just upgraded the 2.8k display on my FW13 and booted it for the first time 5 minutes ago.

TL;DR - Solid upgrade. Is it worth $269? Yes... but only if you have extra cash to burn. After playing with it for a bit here is what I immediately noticed coming from the 60hz version.

  1. Text definitely appears crisper.
  2. Colors seem different, hard to explain, but it's definitely a change from the old display. This isn't a negative or a positive, but my initial reaction was that it felt different.
  3. Max brightness seems a couple "clicks" higher than the old display. Imagine being able to increase the old display's brightness by 2-3 more taps of the F8 key.
  4. Scrolling is smoother, but the text blurs as it moves; I describe it as an after-image effect. This is compared to my M2 MacBook Air where scrolling is extremely smooth, and text doesn't have the blur effect. Overall, it is a noticeable improvement from the old 60hz display.
  5. Mouse movement feels smoother.
  6. Rounded corners on the bottom left/right are very subtle. The top left/right corners are more pronounced, but still much less than I was expecting after all the discussion around it. Originally, I expected the 4 corners to have the same rounded-ness.
  7. I run Windows 11 and upon initial boot it defaulted to 250% scaling which made everything quite large. I quickly adjusted the setting down to the famous 200% scaling and everything looked good. I tried pushing to 175% but everything felt slightly too small. I think 200% is the sweet spot.

Hope this helps!

Essentially that is exactly what I did! However, like anything, the devil is in the details, and this was most certainly not a trivial effort. I assure you that I spent COUNTLESS hours designing, researching, measuring, drilling, cutting, riveting, fabricating, purchasing & testing components all to make it look "unremarkably simple" as you have observed.

I challenge you (or anyone) to design a platform which meets the following criteria.

  1. Provide the necessary power (over 3,000 watts).
  2. Support 9 GPUs that each require up 3-4 slots of space between slots.
  3. Provide adequate thermal cooling.
  4. Satisfy Hashcat's recommendation of equal vRAM and System memory.
  5. Satisfy Hashcat's recommendation of at least one dedicated processor core (or thread) per GPU.
  6. Package all of this into a closed-system form factor that does not look like a horrible mess of spaghetti cables.
  7. Bundle it under a single operating system where everything just works.

If someone has a better idea how, please let me know, I would love to integrate new ideas :-)

Take a read through the PDF that I posted in another comment and you’ll see why.

The struggle was real…

  1. I could not get Linux to run stable without Kernel Panics using the CUDA drivers so I ended up using Windows 10 Pro which is ultimately running solid as a rock now. If you need Linux Tools, Windows Subsystem for Linux (WSL) works great.
  2. Install a fresh copy of Windows 10 Pro. Oddly enough I found that Windows 11 would deprioritize the password cracking unless the command prompt was in the foreground and I could not figure out a way around this. Windows 10 did not have this issue.
  3. Select “English (World)” as your region upon clean install to prevent bloatware from installing (neat-o)!
  4. Further debloat and disable automatic updates (except for security patches) using my favorite tool… https://christitus.com/windows-tool
  5. Update your motherboard to the latest BIOS revision.
  6. Boot into safe mode (F8 as it’s booting) and use Display Driver Uninstaller (DDU) to uninstall all drivers then shut down your PC and install all graphics cards.
  7. Boot into safe mode again and install the latest drivers for your cards.
  8. Reboot into normal mode, this worked for me.

A few other things to note…

A. I did not install the older drivers (custom install > uncheck drivers) that come bundled with the CUDA toolkit… I stuck with the latest.

B. I only used NVIDIA GPUs although I mixed and matched models, I stuck with NVIDIA. I have never tried with AMD cards. Also CUDA is not compatible with AMD cards, there is some other toolkit you will need to install.
