# MAX POWER
# 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


Attack modes

-a 0 # Straight : hash dict
-a 1 # Combination : hash dict dict
-a 3 # Bruteforce : hash mask
-a 6 # Hybrid wordlist + mask : hash dict mask
-a 7 # Hybrid mask + wordlist : hash mask dict

Examples

# Benchmark MD4 hashes
hashcat -b -m 900

# Create a hashcat session to hash Kerberos 5 tickets using wordlist
hashcat -m 13100 -a 0 --session crackin1 hashes.txt wordlist.txt -o output.pot

# Crack MD5 hashes using all char in 7 char passwords
hashcat -m 0 -a 3 -i hashes.txt ?a?a?a?a?a?a?a -o output.pot

# Crack SHA1 by using wordlist with 2 char at the end 
hashcat -m 100 -a 6 hashes.txt wordlist.txt ?a?a -o output.pot

# Crack WinZip hash using mask (Summer2018!)
hashcat -m 13600 -a 3 hashes.txt ?u?l?l?l?l?l?l?d?d?d?d! -o output.pot

# Crack MD5 hashes using dictionnary and rules
hashcat -a 0 -m 0 example0.hash example.dict -r rules/best64.rules

# Crack MD5 using combinator function with 2 dictionnaries
hashcat -a 1 -m 0 example0.hash example.dict example.dict

# Cracking NTLM hashes
hashcat64 -m 1000 -a 0 -w 4 --force --opencl-device-types 1,2 -O d:\hashsample.hash "d:\WORDLISTS\realuniq.lst" -r OneRuleToRuleThemAll.rule

# Cracking hashes from kerberoasting
hashcat64 -m 13100 -a 0 -w 4 --force --opencl-device-types 1,2 -O d:\krb5tgs.hash d:\WORDLISTS\realhuman_phill.txt -r OneRuleToRuleThemAll.rule
# You can use hashcat to perform combined attacks
# For example by using wordlist + mask + rules
hashcat -a 6 -m 0 prenoms.txt ?d?d?d?d -r rules/yourule.rule

# Single rule used to uppercase first letter --> Marie2018
hashcat -a 6 -m 0 prenoms.txt ?d?d?d?d -j 'c'


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
.\hashcat64.exe -m 1000 hashs.txt -a 6 .\french\* -1 .\charsets\custom.chr '?1' -j c --force -O
.\hashcat64.exe -m 1000 hashs.txt -a 6 .\french\* -1 .\charsets\custom.chr '?d?1' -j c --force -O

.\hashcat64.exe ...

# 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 -m 1000 hashs.txt --potfile-path potfile.pot -a 0 french.txt -r .rules\best64.rule --force -O
.\hashcat64.exe -m 1000 hashs.txt --potfile-path potfile.pot -a 0 french.txt -r .rules\OneRuleToRuleThemAll.rule --force -O
.\hashcat64.exe -m 1000 hashs.txt --potfile-path potfile.pot -a 0 french.txt -r .rules\best64.rule --force -O
.\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)
.\hashcat64.exe -m 1000 hashs.txt --potfile-path potfile.pot -a 3 '?u?l?l?l?d?d?d?d' --force -O
.\hashcat64.exe -m 1000 hashs.txt --potfile-path potfile.pot -a 3 '?u?l?l?l?l?d?d?d' --force -O
.\hashcat64.exe -m 1000 hashs.txt --potfile-path potfile.pot -a 3 '?u?l?l?l?l?l?d?d' --force -O
.\hashcat64.exe -m 1000 hashs.txt --potfile-path potfile.pot -a 3 -1 .\charset\custom '?u?l?l?l?l?l?d?1' --force -O
.\hashcat64.exe ...

# Then increment mask size and play again
# Can be longer for 9 char and above.. Up to you to decide which masks and how long you wanna wait
.\hashcat64.exe -m 1000 hashs.txt --potfile-path potfile.pot -a 3 '?u?l?l?l?d?d?d?d?d' --force -O
.\hashcat64.exe -m 1000 hashs.txt --potfile-path potfile.pot -a 3 '?u?l?l?l?l?d?d?d?d' --force -O
.\hashcat64.exe -m 1000 hashs.txt --potfile-path potfile.pot -a 3 '?u?l?l?l?l?l?d?d?d' --force -O
.\hashcat64.exe ...

# If you have few hashes and small/medium wordlist, you can use random rules
# And make several loops
.\hashcat64.exe -m 1000 hashs.txt --potfile-path potfile.pot -a 0 wl.txt -g 1000000  --force -O -w 3

# You can use combination attacks
# For example, combine different names, or combine names with dates.. Then apply masks
# Directly using hashcat
.\hashcat64.exe -m 1000 hashs.txt --potfile-path potfile.pot -a 1 wordlist1.txt wordlist2.txt --force -O
# Or in memory feeding, it allows you to use rules but not masks
.\combinator.exe wordlist1.txt wordlist2.txt | .\hashcat64.exe -m 1000 hashs.txt --potfile-path potfile.pot -a 0 -rules .\rules\best64.rule --force -O
# Or create the wordlist before and use it
.\combinator.exe wordlist1.txt wordlist2.txt
.\hashcat64.exe -m 1000 hashs.txt --potfile-path potfile.pot -a 6 combinedwordlist.txt '?d?d?d?d' -j c --increment --force -O

# Finally use your already cracked passwords to build a new wordlist
.\hashcat64.exe -m 1000 hashs.txt --potfile-path potfile.pot --show | %{$_.split(':')[1]} > cracked.txt
.\hashcat64.exe -m 1000 hashs.txt -a 6 cracked.txt '?d?d?d?d' -j c --increment --force -O
.\hashcat64.exe -m 1000 hashs.txt -a 0 cracked.txt -r .rules\OneRuleToRuleThemAll.rule --force -O

# You can also checks the target in popular leaks to find some password
# Then try reuse or rules on them
