A penetration tester discovered a new exploit and would like to create a Metasploit module. Which of the following programming languages would be best for the penetration tester to use?

JavaScript is primarily a client-side web scripting language and is not the native language for Metasploit module development.

Python is a versatile scripting language used in many security tools, but it is not the native language for Metasploit module development.

Perl is an older, powerful scripting language often used for text processing and system administration, but it is not the primary language for Metasploit modules.

The Metasploit Framework is primarily written in Ruby, and all Metasploit modules (exploits, payloads, auxiliary, post-exploitation) are developed using the Ruby programming language. Therefore, Ruby is the best choice for creating new modules that integrate seamlessly with the framework.
