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. Continue reading Reversing Java: Part III
Recently I’ve interested in byte code structure of Java and Dalvik. I’ve found some useful tools for playing with them.
Destination Byte Code
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).
