newbie need help in setting hashcat command with some rules

[philsmd]

you could use permute from hashcat-utils (input dict containing "V5e7gt" without quotes) to generate all the permutations for the 6 chars.

After that you need to add the remaining six ?1 e.g. a mask file like this:

Code:

?l?u?d,?1?1?1?1?1?1V5e7gt
?l?u?d,?1?1?1?1?1?15Ve7gt
?l?u?d,?1?1?1?1?1?1eV57gt
?l?u?d,?1?1?1?1?1?1Ve57gt
?l?u?d,?1?1?1?1?1?15eV7gt
?l?u?d,?1?1?1?1?1?1e5V7gt

etc etc etc

you need to change the position of the ?1 to any position in the mask, e.g. also "?15eV7gt?1?1?1?1?1" and "V5e7gt?1?1?1?1?1?1" and "?1V?15?1e?17?1g?1t" etc is possible.

but it's still very, very difficult to run all of these hashcat mask file masks, especially because your hash is using SCRYPT.

It's probably better if you try to remember much more from the password

another method could be to use this as input to permute from hashcat-utils:
ABCDEFV5e7gt

the A and B and C and D and E and F are of course fake here

and you could later replace the output of permute with a "sed" command to e.g. ?1

Code:

permute < dict.txt | sed 's/[A-F]/?1/g' | sort -u

but you will get of course again very, very many combinations.

One optimization could also be to define -1 to not include the characters V5e7gt , this can be done in the first field of your .hcmask file (instead of using ?u or ?d or ?l you just define the chars that you want without the characters that you think are not repeated).
