One of the objectives of this chapter was to learn about the modules that allow us to extract metadata from documents and images, as well as to extract geolocation information from IP addresses and domain names. We discussed how to obtain domain, information such as how technologies and CMS are being used in a certain web page. Finally,we reviewed how to extract metadata from web browsers such as chrome and firefox. All the tools reviewed in this chapter allow us to get information that may be useful for later phases of our pentesting or audit process.
In the next chapter, we will explore programming packages and Python modules for implementing cryptography and steganography.
