Post: RE: Benchmark for RX 7900XT/XTX

It's not 50-60% faster in most of the tests on that page. Based on the Phoronix benchmarks, it's only ~15% faster.

Mimikatz is probably your best bet, it's been the most consistent for me across all windows versions.

Post: RE: LM & NTLMv1 + challenge

Attacking the LM Challenge Response in NetNTLMv1 is fairly uncommon and thus not implemented in hashcat. I've recently gone back and did a PoC for this exact attack but I've not pushed it to master ye...

    Thread: cuMemAlloc(): out of memory
Post: RE: cuMemAlloc(): out of memory

You have --force enabled and should read the warning present. Ignoring that for a second, you have 6x 3090 but almost no system RAM. You should have 144gb of system RAM to account for the possible ...

Post: RE: generating actual hashes to stdout

Hashcat accomplishes this by running ingested hashes through each of our module parsers one at a time and reviewing the output for proper tokenization/parsing. It will give you all possibilities for h...

Sounds like your dictionary is relatively small and/or your host is having trouble streaming it to the GPU sufficiently. The speed bump is likely because there's a period where the GPU is left without...

    Thread: generating actual hashes to stdout
Post: RE: generating actual hashes to stdout

Hashcat can't do this for a handful of reasons but mainly, it'd be very very slow and would take a lot of resources for a GPU to do this. Your best bet is to copy the algorithm to a script or utility ...

Bitcoin/Litecoin hashes have variable difficulty and thus varying speeds. Your benchmark of ~14kh/s per A100 is pretty much exactly on target for what I would expect. The speeds you are seeing in the ...

Post: RE: Association Attack & potfiles

The reason it doesn't allow use of the potfile now is that the potfile is NOT an outfile. It's a file that hashcat uses to remove previously cracked hashes from it's current run. We currently can't su...

Hashcat does not have the ability to remove the duplicate hashes, the user must do so themselves.
