Attack NTLM hashes using wordlist, enable custom kernels (limits lenght of pass to 27, better speed), use workload 3, ensure we use a session and save in cracked_hashes
hashcat -a 0 -m 1000 -O -w 3 hashfile wordlist -o cracked_hashes --session=crack_these_hashes
To restore this session run
hashcat --session=crack_these_hashes --restore
hashcat -a 0 -m 1000 -O -w 3 hashfile wordlist -o cracked_hashes --session=crack_these_hashes -r rule
hashcat -m 500 hashes.txt -a 3 ?1?1?1?1?1?1?1?1 --increment -1 ?l?d?u
hashcat -m 500 hashes.txt -a 3 'Welkom?1?1?1' --increment -1 ?l?d?u
predefined charsets
?l = abcdefghijklmnopqrstuvwxyz
?u = ABCDEFGHIJKLMNOPQRSTUVWXYZ
?d = 0123456789
?s = «space»!"#$%&'()*+,-./:;<=>?@[\]^_`{|}~
?a = ?l?u?d?s
?b = 0x00 - 0xff
?l?d?u is the same as:
?ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789
hashcat -a 0 -m 1000 -O hashfile wordlist -o cracked_hashes --username
hashcat -m 1000 hashfile --show --username

PRINCE (PRobability INfinite Chained Elements) is a hashcat utility for randomly generating probable passwords:
pp64.bin --pw-min=8 < dict.txt | head -20 shuf dict.txt | pp64.bin --pw-min=8 | head -20
Purple Rain attack uses a combination of Prince, a dictionary and random Mutation rules to dynamicaly create infinite combinations of passwords.
shuf dict.txt | pp64.bin --pw-min=8 | hashcat -a 0 -m 1000 -w 3 -O hashes.txt -g 300000
sort passwords.txt | uniq -c | grep -v "1 " | sort -rn
grep -wif users.txt username_hash_password.txt
sed 's/\$krb5tgs\$\(.*\):\(.*\)/\$krb5tgs\$23\$\*\1\*\$\2/' kerbs.txt
echo HEX | xxd -ps -r | iconv -f cp1252 -t utf8
