Onion Tunnel is a simple tunnel app for tunneling every connection through TOR network. It is in my GitHub repository named OnionTunnel: https://github.com/mirsamantajbakhsh/OnionTunnel.
I was researching about Android Malware and their features, compare them. I’ve found that most of them (actually all) do not support live video stream from Android camera, aka Spy Camera, and one that supports live camera, needs an activity. Therefore, I’ve started a hidden spy camera project to live stream video from Android camera to an Rtmp server without activity, named Live Hidden Camera.
In the previous tutorials, I’ve described the simple Java byte code structure and stated to reverse a simple Hello World Java application. In this tutorial, I will describe the remaining parts of the class file.
In the Reversing Java: Part I, I’ve described the main structure of Java class file bytes. In this part, I’ll continue decompiling the HelloWorld example.
Recently I’ve interested in byte code structure of Java and Dalvik. I’ve found some useful tools for playing with them.
Java byte codes are simple to reverse engineering because they compile in run time. i.e. JVM will execute the byte codes in run time, thus Java code is cross platform but executes with more delay than direct compiled machine codes (for example using C++ and gcc).
