Combinator will only do 2 of each word. If you would like 4 of each. You can do the following.
Code:
hashcat -a 1 dict1.txt dict1.txt --stdout > dict1combined.txt
hashcat -a 1 dict1combined.txt dict1combined.txt --stdout | hashcat -m 13000 hash.txt
Or for the second line
Code:
hashcat -a 1 -m 13000 hash.txt dict1combined.txt dict1combined.txt
Be mindful that combining wordlist has exponential growth. So if you start doing it 4 or 5 times it will be terrabytes in size.
