TheBhTiNjector is a file binder that concatenates files while preserving their functionality.

Basically, it concatenates multiple types of files, which can be executables, images or executables with images, uniting them and having the possibility of injecting shellcode.

The shortest definition is, a shellcode is a small piece of code used as a payload in exploiting a software vulnerability. And what does it mean? Shellcode is defined as a set of instructions injected and then executed by an exploit. Shellcode is used to directly manipulate the registries and functionality of an exploit, and can even secure a shell on the target machine. For the shellcode to work correctly, you need to pay attention to these aspects:

-- Shellcode Size: The shellcode size cannot exceed the available space in the image, resulting in improper injection.

-- Shellcode Format: The shellcode may not be formatted correctly to run on the target architecture. Make sure the shellcode is compatible with the architecture of the system where the image will run.

-- Poor Testing: If you are not seeing the expected behavior when opening the image, it is possible that your testing is incomplete or inadequate. Make sure you are testing in a suitable environment and that you are observing the results correctly.

First you compile the shellcode, enter the shellcodes directory with cd shellcodes, after entering you can compile them (this may vary depending on your machine) for example:

nasm -f elf32 -o shellcode.o shellcodeWin.asm

ld -m elf_i386 -o shellcode shellcode.o

or:

nasm -f win32 shellcodeWin.asm -o shellcode.obj

Then you move the compiled shellcodes to the main directory.

Then, you compile the main code with your preferred compiler, in this case I will use G++ for example: g++ -o main.exe main.cpp

After you compile, you can run for example: ./main.exe -h which will give you all the options of what to do and how to do it.

After that, you can concatenate the files and inject the shellcode, as in this example:

You can also concatenate binary with binary, as in this example:

You can also inject shellcode into binaries

To contribute to this project you need to make a pull request, and then give us a detailed description of what you want to add or change and we at the black hell team will review the code and authorize it, sometimes editing the implementation a little to maintain good programming practices.
