Network Adapter Selector

THERE IS A PROBLEM WITH UNINSTALLER NOT WORKING, PLEASE DONT DOWNLOAD THIS TOOL IF YOU ARE NOT READY TO INSTALL THIRD PARTY APPLICATION TO REMOVE IT LATER

A solution containing an Injector to hook WinSock methods and bind the new connections to the specific network adapter along with a Shell Extension to simplifies the process of injecting the code into other programs.

How to get

Download the latest version of the program from the releases page.

Command line parameters

If you are not interested in using the provided shell extension, you can always use the following command line parameters directly to manipulate running applications or start a new process.

• -d --debug: Debug mode creates a log file in temp directory logging all activities of the injected code. [true, false]
• -n --network: Identification string of the network adapter to bind.
• -a --attach: Process identification number of the process to attach. OR
• -e --execute: Address of the executable file to start.
• -c --args: Arguments to be sent to the executable file.
• -t --delay: Delay in milliseconds before trying to inject the code.

Network Identification String

Network identification string is the network GUID in {00000000-0000-0000-0000-000000000000} format, all uppercase. To get those you can run the following commands in the CMD to start the "Wired AutoConfig" and "WLAN AutoConfig" services and list network adapters:

net start "Wired AutoConfig"
net start "WLAN AutoConfig"
netsh lan show interfaces
netsh wlan show interfaces

Or use the following code in a PowerShell window that uses .Net libraries to produce a similar result:

[System.Net.NetworkInformation.NetworkInterface]::GetAllNetworkInterfaces()

Also, you can use the registry and read them from the following path directly:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\NetworkCards

Examples

Attaching to an already running process: (PID 1234)

NetworkAdapterSelector.Hook.exe --network "{ABCDEFGH-0000-0000-0000-000000000000}" --attach 1234

Starting a new instance of notepad.exe and attaching to it after one second:

NetworkAdapterSelector.Hook.exe --network "{ABCDEFGH-0000-0000-0000-000000000000}" --execute "C:\Windows\System32\notepad.exe" --delay 1000

Technology

Both parts of the solution are in pure C# using EasyHook library and SharpShell framework. It was a little experiment to see how stable is EasyHook and how SharpShell can perform in terms of performance.
