What is it?

Native QuasarClient is a native implementation of the client part for QuasarRAT. Since the original client is created in C# and depends on the .NET framework it creates some portability issues. This client aims to maximize the clients portability by creating it in C++ and using native APIs for multiple platforms and operating systems.

Compiling on windows

(Requires proper setup of MinGW including PATH environment variables set to use build script)

1. Clone the repository
   • > git clone --recursive https://github.com/UbbeLoL/Native-QuasarClient.git
2. Navigate to the NativeClient directory
   • > cd .\QuasarRAT\NativeClient
3. Run "build-(configuration)-(toolset).bat"

Compiling on linux

(Step 2 to 4 is only required first compilation)

1. Clone the repository
   • $ git clone --recursive https://github.com/UbbeLoL/Native-QuasarClient.git
2. Navigate to the CryptoPP directory
   • $ cd ./QuasarRAT/NativeClient/cryptopp
3. Build cryptopp (Only need to do this once)
   • $ cmake CMakeLists.txt && make
4. Create "lib/" directory and copy "cryptopp.a" to it
   • $ mkdir ../lib && mv libcryptopp.a ../lib/libcryptopp.a
5. Navigate to the NativeClient directory
   • $ cd ../
