Exploit Development Tools
They are software tools that help developers to create and test exploits. Exploits are pieces of code that take advantage of vulnerabilities in software to gain unauthorized access to a computer system or network. They can be used to identify and exploit vulnerabilities in a variety of software, including operating systems, web applications, and database systems.
