In this chapter, we will cover the following topics:
- Gathering information using the Shodan API
- Scripting a Google+ API search
- Downloading profile pictures using the Google+ API
- Harvesting additional results using the Google+ API pagination
- Getting screenshots of websites using QtWebKit
- Screenshots based on port lists
- Spidering websites
Open Source Intelligence (OSINT) is the process of gathering information from Open (overt) sources. When it comes to testing a web application, that might seem a strange thing to do. However, a great deal of information can be learned about a particular website before even touching it. You might be able to find out what server-side language the website is written in, the underpinning framework, or even its credentials. Learning to use APIs and scripting these tasks can make the bulk of the gathering phase a lot easier.
In this chapter, we will look at a few of the ways we can use Python to leverage the power of APIs to gain insight into our target.
