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