Iterate numbers 0000 to 9999 in Combo Attack

[atom]

What you need is to create a rulset that is doing insert rules 0000-9999 and then do a tripple combinator attack using the first hashcat in -a 1 --stdout mode piping into a second hashcat where you use. This works because the first wordlist has a fixed length 5, so you'll start your insert at position 5
