All the binaries located in the **Startup folders are going to be executed on startup**. The common startup folders are the ones listed a continuation, but the startup folder is indicated in the registry. [Read this to learn where.](privilege-escalation-with-autorun-binaries.md#startup-path)
```bash
dir /b "C:\Documents and Settings\All Users\Start Menu\Programs\Startup" 2>nul
dir /b "C:\Documents and Settings\%username%\Start Menu\Programs\Startup" 2>nul
dir /b "%programdata%\Microsoft\Windows\Start Menu\Programs\Startup" 2>nul
dir /b "%appdata%\Microsoft\Windows\Start Menu\Programs\Startup" 2>nul
Note: The **Wow6432Node** registry entry indicates that you are running a 64-bit Windows version. The operating system uses this key to display a separate view of HKEY\_LOCAL\_MACHINE\SOFTWARE for 32-bit applications that run on 64-bit Windows versions.
Run and RunOnce registry keys cause programs to run each time that a user logs on. The data value for a key is a command line no longer than 260 characters.
It's not created by default on Windows Vista and newer. Registry run key entries can reference programs directly or list them as a dependency. For example, it is possible to load a DLL at logon using a "Depend" key with RunOnceEx: `reg add HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnceEx\0001\Depend /v 1 /d "C:\temp\evil[.]dll"`
**Exploit 2**: If you can overwrite any of the binaries indicated on any of the registry inside **HKLM** you can modify that binary with a backdoor when a different user logs in and escalate privileges.
Any shortcut created to the location pointed by subkey Startup will launch the service during logon/reboot. Start up location is specified both at Local Machine and Current User.
If you can overwrite any \[User] Shell Folder under **HKLM**, you will e able to point it to a folder controlled by you and place a backdoor that will be executed anytime a user logs in the system escalating privileges.
Under the registry key `HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SafeBoot` is the value **AlternateShell**, which by default is set to `cmd.exe` (the command prompt). When you press F8 during startup and select "Safe Mode with Command Prompt," the system uses this alternate shell.\
3. Add a line similar to the following: `multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /fastdetect /SAFEBOOT:MINIMAL(ALTERNATESHELL)`
**Exploit 2 (PATH write permissions)**: If you have write permission on any folder of the system **PATH** before _C:\Windows\system32_ (or if you can change it) you can create a cmd.exe file and if someone initiates the machine in Safe Mode your backdoor will be executed.
**Exploit 3 (PATH write permissions and boot.ini write permissions)**: If you can write boot.ini, you can automate the startup in safe mode for the next reboot.
Active Setup runs before the Desktop appears. Commands started by Active Setup run synchronously, blocking the logon while they are executing. Active Setup is executed before any Run or RunOnce registry entries are evaluated.
Inside those keys you will find more keys and each for those will home some interesting key-values. The most interesting ones are:
* This is the command that is executed if Active Setup determines this component needs to run during logon.

If you could write/overwrite on any Key with _**IsInstalled == "1"**_ the key **StubPath**, you could point it to a backdoor and escalate privileges. Also, if you could overwrite any **binary** pointed by any **StubPath** key you could be able to escalate privileges.
A **Browser Helper Object** (**BHO**) is a DLL module designed as a plugin for Microsoft's Internet Explorer web browser to provide added functionality. These modules are executed for each new instance of Internet Explorer and for each new instance of Windows Explorer. However, a BHO can be prevented to be executed by each instance of Explorer setting the key **NoExplorer** to 1.
Note that the registry will contain 1 new registry per each dll and it will be represented by the **CLSID**. You can find the CLSID info in `HKLM\SOFTWARE\Classes\CLSID\{<CLSID>}`
