Reverse engineering has its origin in mechanical engineering. To obtain information to understand how a machine or mechanical device works, 3D scanning, computed tomography, ultrasonic measurement, and other methods are used even today. Reverse engineering reverses the engineering process that designs and assembles components of a product to create a functional device.

Reverse engineering aims at uncovering information on how the individual components of a product function, helping you to gain a complete understanding of each component and the entire system. This is precisely why this process is often applied to competing products so that a product can be improved or adapted and survives in the competitive market. Reverse engineering has a lot of other uses and isn’t just hardware.

Processes of reverse engineering software              

Reverse engineering is required for both the investigation of industrially manufactured products as well as software reconstruction.

Recovering software source code

Source code is a text written in a programming language for a computer program. The computer converts that human-readable text into a machine-readable language automatically. To be able to open-source code for software, machine language translation needs to be reversed. To this end, a decompiler is used. This is a computer program that uses the binary machine code to generate human-readable source code. The process of retranslating the machine-readable binary code into human-readable source code is automatically carried out.

Understanding the rules of a communication protocol

Reverse engineering is also used when developers wish to write drivers for operating systems but the knowledge about the operating system’s exact functioning and structure is secret. The rules of a communication protocol are made accessible with the aid of a sniffer. A sniffer is a data traffic analyzing software tool within a network.

Subsequent creation of a software prototype

The term code feedback is used in this case, instead of reverse engineering. The software’s rebuilt source code is modified and transferred to a prototype to be further processed there. Now software projects can be completed and subsequently generated with the graphical modeling language UML.

When is reverse engineering used for software?

• Testing and quality management of software
• Further development of software
• Investigation of network communication protocols
• Detection of computer viruses, trojans, extortion software, and other malicious programs
• Moving or maintenance of abandoned programs
• Search for software bugs
• General examination of a file format for your understanding
• Improve software compatibility with third-party platforms and software
• Use of undocumented platform functions
