    Thread: New Attack-Mode: Association Attack
Post: RE: New Attack-Mode: Association Attack

"Association" is a general term here that allows attacks to be targets *on a per-hash basis*. In other words, you don't have to try each word against each hash. Instead, you can try just one word ag...

Huh - when I did my veracrypt testing in late 2018, it used the filename. This seems like the approach that would cause the least amount of confusion. Otherwise, we'll have a steady stream of users as...

Post: RE: low-end CPU recommendation.

FWIW, for some attacks I've seen it's good to have one core per GPU. I haven't seen anything that would benefit from multiple cores per GPU.

If you GPU is consistently showing 100% utilization, you're supplying enough work for the GPUs to not be bored. For a slower hash like the WPA family, speeds like you're showing aren't unreasonable, b...

if you quit, you can restore with --restore. If you're using the default session name (not specifying an alternate one), then "hashcat --restore" (with no other parameters) will pick up where you left...

It's the product of both rulesets - rule 1 from list 1 AND rule 1 from list 2, etc etc. This is one reason why ':' (do nothing) is often included in rulesets, so that each rule from each wordlist i...

Post: RE: combine rules without duplicates?

Dedupe of text on the command line is a largely solved problem. Depends on your platform. 'sort -u' on Unix-likes covers most use cases. On Windows, 'sort.exe /unique' seems roughly equivalent.
