Penetration testing utility and antivirus assessment tool.
Built with Visual Studio Community 2019 v16.9.3 (64-bit) and tested on Windows 10 Enterprise OS (64-bit).
Made for educational purposes. I hope it will help!
This repository started to have known signatures and I don't have time to upload new executables each time so you should compile this project yourself.
Some features may require administrative privileges.
Check the library here. Feel free to use it!
Run Invoker_x86.exe (32-bit) or Invoker_x64.exe (64-bit).
To automate the backdoor while setting up a persistence, run the following command:
32-bit Invoker can:
64-bit Invoker can:
Elevate privileges by injecting bytecode into a higher-privileged process.
This tool can parse an HTTP response as well as extract the payload from a custom element, e.g. from
payload is a binary code/file encoded in Base64.
Check the example at pastebin.com/raw/xf9Trt0d.
This might be useful if antivirus is constantly deleting your local payloads.
Also, check an additional example at pastebin.com/raw/iW17rCxH - payload hidden in the image element.
P.S. Bytecodes provided will most certainly not work for you.
Use ngrok to give your local web server a public address.

If you wish to run a PowerShell reverse or bind shell from the Invoker, check my other project.
Just copy and paste any of the one-liners in your PowerShell session.
Direct system calls library and assembly were generated with SysWhispers2. Credits to the author! As of this writing, this tool only supports 64-bit direct system calls.
To generate the same library and assembly, run the following command from your preferred console:
python syswhispers.py -f NtOpenProcess,NtClose,NtAllocateVirtualMemory,NtWriteVirtualMemory,NtFreeVirtualMemory,NtCreateThreadEx -o syscalls

Find out how to make a simple DLL with a hook procedure here. The hook procedure will invoke a message box on each window close.
Also, check out a keyboard hook procedure (i.e. keylogger) here.
Always remove all the created artifacts after you are done testing, e.g. remove
Run the Invoker as administrator.
Enable all access token privileges.
Duplicate the access token from e.g. Windows Logon Application (winlogon.exe) and run a new instance of the Invoker.
Within the new Invoker instance, open the Command Prompt and run
whoami, you should now see
Enable all access token privileges once again.
Close the old Invoker instance.
P.S. You get more access token privileges from Local Security Authority Subsystem Service (lsass.exe).
