Repeating Character in Mask Attack

[monyanus]

Well, an easy way to do that would be to use a combinator attack:

hashcat –m 0 –a 1 my.hash mywordlist.txt



Lazy and quick answer, so not speed optimised. If the options are not that many, you can simply create a custom word list and run a combination attack with the word list. All combinations of all words on each line will be tried, starting with the fewest combinations (e.g. first 1 words, combinations of 2 words, combinations of 3 words etc.)
If there are to many options, you can divide the first and second part over two word lists, see second link:
