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.
