About the Author

Paulino Calderón Pale (@calderpwn) is a very passionate software developer and penetration tester from a Caribbean island in México called Cozumel. He learned to write code and administer IT infrastructures early in his life—skills that came handy when he joined the information security industry. Today, he loves learning new technologies, penetration testing, conducting data-gathering experiments, developing software, and contributing to the open source community. He maintains a blog of his public work at http://calderonpale.com.

In the summer of 2011, he joined Google’s Summer of Code program to work on the Nmap project as an NSE (Nmap Scripting Engine) developer. He focused on improving the web scanning capabilities of Nmap and has produced over 20 scripts for gathering information, and detecting and exploiting security vulnerabilities since then.

He is the cofounder of Websec, an information security company focused on web security operation in México (http://websec.mx) and Canada (http://websec.ca), where they help companies in different industries secure their IT infrastructures.
