OllyDbg

OllyDbg is a free software tool used for analyzing and debugging computer programs, particularly those written for Windows. It allows users to see how a program operates by breaking it down into its individual parts, examining its code, and monitoring its behavior while it runs. This is especially useful for software developers and security professionals to identify bugs, understand how software works, or detect malicious activity. OllyDbg provides a user-friendly interface, making it easier for users to navigate complex program structures without needing extensive programming knowledge.
