Using public resources
On the internet, there are several public resources that can be used to collect information regarding a target domain. The benefit of using these resources is that your network traffic is not sent to the target domain directly, so your activities are not recorded in the target domain log files.
The following are the resources that can be used:
Due to the ease of use—you only need an internet connection and a web browser—we suggest that you utilize these public resources first before using the tools provided with Kali Linux.
To protect a domain from being abused, we have changed the domain name that we used in our examples. We are going to use several domain names, such as example.com from IANA and the free hacking testing site https://www.hackthissite.org/ as well, for illustrative purposes.
