DLLirant is a tool to automatize the DLL Hijacking researches on a specified binary.
You need to install Visual Studio Community Edition or superior.
Start DLLirantDLL.sln in the directory "DLLirantDLL" to update the Visual Studio version on the project and select "Release x64" in the Visual Studio top menu and close Visual Studio (just one time).
In a first time you need to start a command line with the tool x64 Native Tools Command Prompt for VS (search with the windows touch)
Use the cd command to your DLLirant directory and to test a binary:
python3 DLLirant.py -f "C:\THEFULLPATH\YourBinary.exe"
The script will create an output directory in the same directory of DLLirant.py, copy the targeted binary to the output directory.
Via the dumpbin tool from Visual Studio, the script will extract the dll names required by the binary, and test each imports functions available one by one by compilate a custom DLL with the required exported functions.
If a function required by the binary is executed, the custom DLL will create a C:\\DLLirant\\output.txt file and display a MessageBox to be sure that a DLL Hijacking is possible.
A results.txt will be also created in the DLLirant directory with all potential DLL Hijacking available.
A file admin-required.txt will also be available for the potential DLL Hijacking who require specific privileges.
If a binary require a DLL from the system or another one, you can create a import directory in the same directory of DLLirant.py the script will copy all your DLL files in the output directory with your targeted binary.
