Crunch: Creating Unicode Wordlists
Many languages include Extended or Unicode character. We can make a wordlist using “Unicode” characters with Crunch. The “mixalpha-space-sv” character set contains some of them.
As seen below:
mixalpha-space-sv = [abcdefghijklmnopqrstuvwxyzåäöABCDEFGHIJKLMNOPQRSTUVWXYZÅÄÖ ]
We can use this character set to build a wordlist.
     sudo crunch 3 5 -f charset.lst mixalpha-space-sv -o mixedall.txt
We now have a mixed character list for password cracking. We could take this and combine it with the previous “1 to 5 number” list for a pretty useful combination. Or we could use it in a hybrid attack having Hashcat add the numbers.
As seen below:
      hashcat --remove -m 0 uncracked.txt -o cracked.txt -i -a6 mixedall.txt ?d?d?d?d -O
We will cover Hashcat in depth in a later chapter. For now, just know that the command above would take...
