Framework for investigating VM-based Android packers

A aramework for investigating VM-based Android packers

In this project, we proposed a novel framework to investigate the VM-based Android packers with the following advantages：

1. An cross-layer dyanmic intrumention approach for monitor the behaviors of VMs;
2. An novel symbolic-based approach to reverse-engineer the customized VMs;
3. An new semantic analysis approach to recognize the semantics of the new customized bytecode.

For more details, please refer to the following paper.

parema's Issues

可否请您给出一个Parema的使用说明

您好，我最近也在进行Android App脱壳的研究，将parema代码下载到本地，尝试配置环境运行测试，但是每一步都有报错，比如安装valgrind会显示缺少文件，脚本中的valgrind模块似乎没有get_constraint_groups方法但是被使用了，

也可能是我水平有限没有理解透彻，可否请您给出一个Parema的使用说明，谢谢！

how do i use parema

Is this project suitable for learning about VM protection?
how do i use it.
