How to Find Technical Information for Ethical Hacking


What Information You Are Looking For

As mentioned in the previous video, we are looking for technical information when performing our reconnaissance. We are also looking for passive information that can be gleamed by anyone and non-technical information like emails and passwords.

One important tool we can use for reconnaissance is Google. For example, we can search “” in Google to reveal only results that include that phrase exactly. This will provide you with many different emails and contact information that is crucial in reconnaissance. You can also use the term “filetype:ext” to find only files of a specific type, replacing “ext” with the file extension (i.e. pdf).

Surprisingly enough, it is very easy to convince a CEO, executive, or other member of an organization if you have access to their contact information. By gathering information on individual employees, you can leverage your knowledge for social engineering. For example, a bank employee who is an avid stamp collector is more likely to open an email about a new stamp collection than another type of email.

Another tool that is very useful for gathering information is With this site you can search for information on an individual by providing some information upfront. is another, similar site limited to the US that provides detailed results. However, some of the results are behind a paywall. Of course, we can also use social media sites like Facebook and LinkedIn to gather information on an individual. When performing reconnaissance, it is important to gather as much useful information as you can. While you may not end up using all of it, it is better to have a wide variety of information available to use. As this is an ethical hacking course, it’s important that you do not compromise your ethics for manipulation and self-gain.
