# goron

Yet another llvm based obfuscator.

当前支持特性：

 - 混淆过程间相关

 - 间接跳转,并加密跳转目标(-mllvm -irobf-indbr)

 - 间接函数调用,并加密目标函数地址(-mllvm -irobf-icall)

 - 间接全局变量引用,并加密变量地址(-mllvm -irobf-indgv)

 - 字符串(c string)加密功能(-mllvm -irobf-cse)

 - 过程相关控制流平坦混淆(-mllvm -irobf-cff)

## 混淆效果

- ### 未混淆

- ### 间接跳转(-mllvm -irobf-indbr)

- ### 间接函数调用(-mllvm -irobf-icall)

- ### 间接全局变量引用(-mllvm -irobf-indgv)

- ### 字符串(c string)加密功能(-mllvm -irobf-cse)

- ### 过程相关控制流平坦混淆(-mllvm -irobf-cff)

## 下载

```

git clone https://github.com/amimo/goron.git -b llvm-7.1.0

```

## 编译

```

cd goron

mkdir build

cd build

cmake -DCMAKE_BUILD_TYPE=Release -DLLVM_ENABLE_ASSERTIONS=ON -DLLVM_ENABLE_PROJECTS=clang -G "Unix Makefiles" ../llvm

make -j12

```

## 使用

跟ollvm类似,可通过编译选项开启相应混淆.

如启用间接跳转混淆

```

$ path_to_the/build/bin/clang -mllvm -irobf -mllvm --irobf-indbr test.c

```

对于使用autotools的工程

```

$ CC=path_to_the/build/bin/clang or CXX=path_to_the/build/bin/clang

$ CFLAGS+="-mllvm -irobf -mllvm --irobf-indbr" or CXXFLAGS+="-mllvm -irobf -mllvm --irobf-indbr" (or any other obfuscation-related flags)

$ ./configure

$ make

```
