Course Overview
Hey there! Welcome to our course, Technical Information Gathering With theHarvester. In the Cybersecurity Tools course, you learned how to gather both technical and people information about your target using theHarvester tool. In a red team engagement, one of the most important steps of the whole project is gathering information about your client, and that's because the information that you collect in here will be really useful during the exploitation phase of your engagement. For example, if you do a really good information gathering job, you may find not‑so‑secure servers open to the internet, which can be way easier to exploit than the main company website. So in this course, we'll cover theHarvester, which will help you to automate the information gathering so you can find tons of interesting information about your target. We start by showing how to use theHarvester to find subdomains, and IP addresses that could be interesting for an exploitation phase. Then we also cover how to use the tool to find information about the people that work in the company, such as email addresses, Twitter accounts, and even LinkedIn profiles. So whether you're trying to gather information about a target in a red team engagement or you're just looking to audit the cybersecurity exposure of your own company, join me in learning how to gather technical information with theHarvester tool here, at Pluralsight.
