API-Hashing

A basic exemple of the API-Hashing method used by Red Teamers but also by malwares developers in C++ to avoid IAT entries.

How to compile

• Install LLVM for Windows: https://github.com/llvm/llvm-project/releases/download/llvmorg-16.0.0/LLVM-16.0.0-win64.exe
• Do not forget to check the "Add LLVM to the system PATH for current user" during the installation.

clang++ *.cpp -o output.exe
