Reverse Engineering – Debugging Fundamentals The debugger concept and purpose is to test and troubleshoot another written program. Whether the debugger is a simple script, tool or a more complex computer program the idea is to utilize it in order see and verify the functionality of the “target” program / application in such a form that one can see and understand via the debugger what is happening while the “target” program / application runs and especially when it stops. The “target” program’s / application’s code that is examined (by the debugger) might alternatively be running on an Instruction Set Simulator (ISS). The ISS is a certain form of technique that gives the ability to halt when specific conditions are encountered but which will typically be somewhat slower than executing the code directly on the appropriate (or the same) processor. When the “target” program / application reaches a running condition or when the program cannot normally continue due to a programmin...

How to Reverse Engineer? In this article, we are going to talk about RCE, also known as reverse code engineering. Reverse code engineering is the process where the code and function of a program is modified, or may you prefer: reengineered without the original source code. For example, if a software programmer has created a program with a bug, does not release a fix, then an experienced end user can reverse engineer the application and fix the bug for everyone using the program. Sounds helpful doesn’t it? That’s because we only touched the tip of the iceberg; the road of reverse engineering is a long one and the end leads to somewhere dark and illegal. Why you wonder? Because, by that logic, computer users can modify the code of any program, alter licensing features of a commercial product and remove critical features to their own liking. For example, a software such as Photoshop that requires you to buy a serial key to register and use it, can be reverse engineered to either ext...
