Re: CUDA NTLM multi-hash bruteforcer

I've got a new release of this that I'm finishing testing & packaging. I will be releasing versions for both 32-bit and 64-bit Linux initially, and am working on learning how to compile this stuff for Windows (where I will be releasing 32-bit binaries). The new version does not interfere with the GU...

Re: about the algorithm used

Hm, I'll look at porting that to CUDA here shortly. Thanks!

Re: CUDA NTLM multi-hash bruteforcer

The source is still in flux, and right now is beyond ugly. I'm working on making it function with a GUI (where it doesn't run into watchdog timer issues) currently.

Re: How high can you get

Overclocking is one of my concerns in distributed computing. I am going to have each client to pass a stability test before getting any work. The problem with this is that it's hard to tell, with a short test (usually run at the beginning) if you have a low but present error rate. I'd assign each w...

Re: How high can you get

My CPU (according to prime95) is unstable as hell and constantly errors out. No crash for nearly a month now, even when running passwordspro on both cores for 4 days straight. Prime95 will catch and report errors in stress test mode. "Running code without crashing" is not the same as "generating co...

Re: How would you build the fastest BarsWF computer?

The Tesla cards are not pushed nearly as hard as a standard gaming card. Their memory is clocked slower, as mentioned they typically have a LOT more of it (4GB is standard), and the cores have some of the graphics bits disabled to reduce power consumption. They also have no display output. They're n...

Re: How high can you get

If your computer can't handle constant running of any codeset, it's not a stable overclock in my opinion.

If BarsWF crashes your computer or fails to return proper results, your computer is overclocked too far.

Re: How would you build the fastest BarsWF computer?

In real life it seems more cost effective to put four cards in two computers and save quite a few bucks - and cooling problems. Or three cards per machine. I haven't worked out the exact numbers, but I believe the "sweet spot" in performance per unit cost (given reasonably unlimited funding) is 3 c...

Re: CUDA NTLM multi-hash bruteforcer

No idea how to actually do that. I suspect it's a lower level than GDM, either at the base X11 level, or in the display drivers.

If you figure out how to do it, let me know & I'll update the readme for future releases.

Re: CUDA NTLM multi-hash bruteforcer

Are you running with X11 installed/running? My code does NOT pay attention to watchdog timers. If there's a watchdog timer killing the process after 5 seconds or so (which appears to be the case, as len6 took around 4 seconds), you will get errors like that. Kill X11, SSH in, and try again. I run my...

Re: CUDA NTLM multi-hash bruteforcer

BarsWF does around 400M, that's correct. My single hash brute forcer for NTLM was around 435M, but that could be optimized to somewhere around 550-600M depending on the hash reversals - I've not played with that yet. I said my effective check rate was around 20B, and that's correct. If there are a l...

Nice one, looks like it is time to spend another 3 hours to set display drivers for my nVidia card under Ubuntu :-) Download nVidia binary driver. Compile against kernel. Insert module.

Re: Quadro FX 5800

The time for the GPU to generate hashes is significantly longer than the time it takes the CPU to sort them. There's no real point in using the GPU to sort things.

And for $3500, I can get a lot more total processing power. Easily 5x more.

CUDA NTLM multi-hash bruteforcer

Threw this together because I didn't want to do real work. It takes a list of up to 1000 hashes, supports arbitrary character sets, and tests through length 8 right now. On an 8800 GTX, with a big hashlist, it gets checkrates up around 20B or a bit higher, depending on the length. It's compiled for ...
