Everything About Reverse Engineering

In today’s article, we will talk about Reverse Engineering and learn about its uses in cybersecurity, and what programming languages are used in this field, the methods, and tools that Reverse Engineering people work with.

First of all, Reverse Engineering is not a science that specializes only in cyber and information security, but it is a science concerned with analyzing the structure of software and hardware to obtain basic information about its manufacture and components.

Reverse engineering is the process of taking apart an object to analyze its components and how they interact with each other in order to identify the object's design principles, its original purpose, and/or its source code. It is typically used to improve a product or uncover potential security vulnerabilities. It can also be applied to non-software systems, such as mechanical and electrical devices.

The uses of Reverse Engineering in the field of cybersecurity :

Reverse Engineering has many uses in the field of cybersecurity, for example, many of us use Cracks to use programs without buying them, but have you ever asked yourself how Cracks works? Cracks are manufactured after the program that we will do the crack for is analyzed, so it analyzes all the steps of the program to know where the protection code for the program comes from. And after the whole program is analyzed, the programmer’s role comes to create Anti-License Software and be in the form of Cracks or Keygen. This is an example of the uses of Reverse Engineering, but it is not the only use. There are many other uses such as security auditing and product analysis. a and in the case of the loss of software documents, and also many companies use Reverse Engineering to analyze competing products for them to know their weaknesses and strengths for the competitive technical intelligence, and also use Reverse Engineering to be a continuous development of companies’ software by analyzing from a reverse point of view Software Improvement.

One of the programming languages that are used in Reverse Engineering is Assembly Language, which is one of the most important programming languages in this field and in many other fields! To explain assembly, we need another article on its own or more, but I will give you a small explanation of it. It is the easy-to-read form for humans of machine language that forms commands and is executed from a computer with a specific core. As for machine language, it is a sequence of bits that represent computer commands.

Reverse Engineering sections :

Reverse Engineering is divided into many sections and we will get to know some of them:

📌 The Reverse Code Engineering

RCE is a branch of software engineering in which a set of techniques and tools are used to arrive at a scheme or model of the program to understand the composition of the program to make it easier for programmers to maintain the program and break the protection or take some code to use in other programs, and all of these things can be used for useful things and negative things because reverse engineering is a double-edged sword.

📌Disassembler

We mean by converting the program from Machine Language to Assembly Language in order to analyze the program.

📌 The Decompiler

The goal is to convert the program code to any other language such as C or C++.

📌 The Packers or un-packers

It is used to decipher the confusion between the interfaces of the program by decoding its files.

📌 The Hex Editing

The goal is to get the Binary Code for the program.

We will go deeper in the next articles.
