Since we only license the rights to use it, is it legal and ethical to reverse engineer software? Are there types of software with which we can alter and change? Reverse engineering software involves analyzing a program to understand how it works, often to create a compatible product or to identify security vulnerabilities. The legality and ethics of reverse engineering depend on the terms of the software license. Some licenses explicitly prohibit reverse engineering, while others may allow it under certain conditions. Types of software that can typically be altered and changed include open-source software, where the source code is freely available for modification. Proprietary software, on the other hand, may have restrictions on modification and reverse engineering. It is important to review the specific license agreement for each software product to determine what actions are permitted
