Cracking a pin number hash with hashcat on Debian Linux.

I recently needed to crack a pin number hash that was four digits and used the numbers 2490. This sounds easy, but hard until you realise that it is a relatively simple PIN. I used the command below to generate a 60 Gigabyte wordlist, containing all possible combinations of the numbers in the PIN.

crunch 16 16 2490 -o pin.lst

Now I am cracking the PIN hash using my generated wordlist.

sudo hashcat -m 120 -a 0 -o cracked2 pin-hash.txt ../Documents/pin.lst -e salt

This was a successful crack as well. I used a 3.4 GHZ i7 Intel CPU and this cracked the PIN hash in no time.

This is the result I got when cracking this hash. This worked so well. A 16 digit PIN made up of the numbers 2 4 9 0.

I then entered the PIN and got this flag.
