How to Create the Rules for This Password Structure

[Chick3nman]

Thank you for your reply! Yes, its a Cisco DPC3941B router and the service is xfinity. Is the dictionary you used online? I would love to use that one! Also, I am new to the hashcat rules: do those rules mean insert 8637 at spaces 5, 6, 7, and 8? But if I want to go through all the combos of numbers do you know how I would do that? For example I would want to go systematically like this:

apple0000anchor
apple0000basket
.....
apple0000zygote
apple0001anchor
.....
apple9999zygote
brick0000anchor

etc. So the last word changes 5000 times before the last number goes up 1, and so on.

Yes, that is how the rule works. You'll need to generate a rule for each number so 10000 rules total. Sounds like a lot but you use the maskprocessor from hashcatutils to generate the rules for you. The list I've used before is available on another forum I'm not sure I can link but the people working on it abandoned it a while ago so It's possible its already outdated. I can try to dig it up if you'd like it.
