Hashcat Cheatsheet

MISC and tricks

# force the CUDA GPU interface, optimize for <32 char passwords and set the workload to insane (-w 4).
# It is supposed to make the computer unusable during the cracking process
# Finnally, use both the GPU and CPU to handle the cracking
--force -O -w 4 --opencl-device-types 1,2

Wrapcat - Automating hashcat commands

Scenario - Cracking large files (eg NTDS.dit)

# Start by making a specific potfile and cracked files (clean environment)
# - domain_ntds.dit
# - domain_ntds_potfile.pot

# Goal is to run many different instances with different settings, so each one have
# to be quite quick

# You can generate wordlist using CeWL
# It usually works pretty well
cewl -d 5 -m 4 -w OUTFILE -v URL
cewl -d 5 -m 4 -w OUTFILE -o -v URL

# With some basic dictionnary cracking (use known wordlists)
# rockyou, hibp, crackstation, richelieu, kaonashi, french and english 
.\hashcat64.exe -m 1000 hashs.txt --potfile-path potfile.pot -a 0 rockyou.txt --force -O

# Then start to use wordlists + masks + simple rule
# For special chars, you can use a custom charset : "?!%$&#-_@+=* "
# Multiple tests, multiples masks and multiples wordlists (including generated ones)
.\hashcat64.exe -m 1000 hashs.txt -a 6 .\french\* '?d?d?d?d' -j c --increment --force -O

# Same commands and behavior but using mask after the tested word (mode 7)
.\hashcat64.exe -m 1000 hashs.txt -a 7 '?d?d?d?d' .\french\* -j c --increment --force -O

# Then, wordlists + complex rules
# Once again run against multiple wordlists (including generated ones)
# Kaonashi and OneRuleToRuleThemAll can produce maaaaaassive cracking time

.\hashcat64.exe ...

# Then smart bruteforce using masks (custom charset can be usefull too)
# Can be quite long, depending on the mask. Many little tests with different masks
# Knowing for example that password is min 8 char long, only 8+ masks
# Play by incrementing or decrementing char vs decimal (you can also use specific charset to reduce time)

# Directly using hashcat
.\hashcat64.exe -m 1000 hashs.txt --potfile-path potfile.pot -a 1 wordlist1.txt wordlist2.txt --force -O
