“In today’s digital life, reverse engineering is crucial as a process for analyzing, understanding, and reconstructing software and systems. This method encompasses various technical and legal challenges, some of which we will explore further. One of the most significant challenges in reverse engineering is the process of analyzing closed-source code. This process is essential for better understanding the functionality of software or systems. However, technical and legal complexities related to reviewing and reconstructing closed-source code can pose obstacles. Another challenge we may encounter in reverse engineering is obtaining the necessary data or resources for analysis and reconstruction. Some systems and software do not provide comprehensive information about their operation, which can disrupt the reverse engineering process. Additionally, legal conflicts are also a significant challenge in this field. The use of reverse engineering to access information in cases that may conflict with intellectual property rights raises complex legal issues that require careful and professional attention. In general, reverse engineering is a powerful tool for analyzing and reconstructing software and systems, but it comes with various technical, legal, and social challenges that necessitate appropriate approaches and
