Help with mask
#1
Hi,

I'm trying to crack a 7z password. I have the hash and have a started a brute force, but as i'm fairly sure what teh make up of the password is I thought a mask would be easier (currently estimated 124 years!!!!).

Could someone help me out?

What I know:
  1. It contains a static 5 letter word. I know what the word is but for the example lets say its 'boats'
  2. Any letter can be uppercase or lower case i.e Boats / BoAts / bOATS
  3. It can have up to 4 numbers before and/or after and im failry certain they are either 1 or 0 ie. 0101boats / 0101boats0101 / 01boats01 / boats01
  4. It may or may not have an '!' mark at the end ie. boats01!

This it the code I'm running at the moment
C:\hashcat1>Hashcat64.exe -a 3 -m 11600 hash.txt

I have the beta installed 4.1.1-2
Windows 10

Thanks

Thanks, I think I've got it up and running well at least it states 1 day to complete rather than 124 years - progress!!!

Just a note, you can severely speed up the attack because your dictionary is very small here.

Code:
hashcat --stdout wordlist.txt -r toggle0.rule -r toggle1.rule -r toggle2.rule -r toggle3.rule -r toggle4.rule -r numbers.rule -r numbers.rule | hashcat -m11600 hash.txt -r numbers.rule -r numbers.rule -r exclamation_mark.rule

This won't give you an estimated end time but you should see much higher speeds than without a pipe.

Thanks I was running it on my laptop anyway. I have a gaming rig that should speed things up no end (1080ti)

This particular attack only has 40000 candidates. Running the second command on your laptop will likely be faster than running the first command on your gaming rig.
