hybrid attack can't use all gpu power? - gentl - 08-15-2019

Hi friends.
a have 5 gpu 1080ti and hybrid attack is exellent in my case
I made wordlist with help of combipow
So i have about 100 words
i use hybrid attack with mask like

Code:
-a 6 -m 11300 hash.txt wordlist.txt -1 dig_symbols.charset ?1?1?1?1?1?1 --increment

It's rather many work to do. But hashcat running about 1 day and only 1 gpu in use with terrible speed 7-10 h/s
Usual speed for 1 gpu is about 5000 H/s

When i use just mask attack with ?a?a?a?a?a?a?a?a - the speed is good, but i don't need such variant.

I already read "How to create more work for full speed?"
But can't understand how i can implement this to my case. Need exact wordlist + mask.

Only one idea came to me - make wordlist with all variants and use Straight attack.

did you try comparing it with a run with the --slow-candidates command line argument ?

RE: hybrid attack can't use all gpu power? - gentl - 08-15-2019

no bro, -a 6 and -a 7 are not supported by --slow-candidates

you can pipe in from another instance like this:

Code:
hashcat -a 6 wordlist.txt -1 dig_symbols.charset ?1?1?1?1?1?1 --increment --stdout | hashcat -m 11300 hash.txt

note that you won't be able to resume and it won't print the ETA

Awesome, bro!!! Now speed is 5000 on all gpu!!
I think this trick should be added to hybrid attack description or FAQ

this type of strategy was since kind of forever discussed in the FAQ under the "more work" question: https://hashcat.net/faq/morework
