Reverse Engineering

Reverse engineering is the process of deconstructing a software program, hardware device, or system to analyze its components and understand its inner workings, often when the original design documents or source code are unavailable. Within computer science, it is used to achieve interoperability between systems, improve upon existing designs, or recover lost data. In the field of cybersecurity, it is a fundamental technique for malware analysis to determine a threat's capabilities, for vulnerability research to discover exploitable flaws, and for digital forensics to investigate the mechanics of an attack.
