Practicing reverse engineering
Since knowing the inputs and outputs cannot, with any surety, provide you with a true picture of the internal construction of the application you want to reverse engineer, let's look at some helpful utilities from Kali Linux that might make it easier. We will look at three debuggers, one disassembly tool, and one miscellaneous reverse-engineering tool.
We will show usage and output from two Linux-based debuggers, Valgrind and EDB-Debugger, and then the similar output from a Windows-only debugger, OllyDbg.
The disassembler is JAD, a Java decompiler.
Demystifying debuggers
What is debugging? The honor of coining the term is often erroneously attributed to Admiral Grace Hopper, on the occasion of her team members finding a physical (but dead) moth stuck in a relay inside a Mark II computer at Harvard University. The term may actually come from Thomas Edison as he mentioned and defined the term as "...little faults and difficulties..." In software development, a bug...
