1. generate a list for the first part
hashcat --stdout -a3 -1 aA -2 bB -3 cC ?1?2?3 -o part1.txt

2. create a file part2.txt that has the three variations of the known parts

3. combine part1 + part2
hashcat --stdout -a1 part1.txt part2.txt -o part1_2.txt

4. add the number
hashcat --stdout -a6 part1_2.txt -1 1234 ?1 -o part1_2_3.txt

5. a custom generator for the last part works best. here is a dirty python script:

Code:

chars = set('asd')

for x in chars:
    other_chars = chars.copy()
    other_chars.remove(x)
    for y in other_chars:
        print('{x}{x}{y}{y}'.format(x=x, y=y))
        print('{x}{x}{y}{y}'.format(x=x.upper(), y=y))
        print('{x}{x}{y}{y}'.format(x=x, y=y.upper()))
        print('{x}{x}{y}{y}'.format(x=x.upper(), y=y.upper()))

python script.py > part4.txt

6. you now have everything you need. Run your attack with
hashcat -a1 part1_2_3.txt part4.txt -m [attack mode] [hash file]
