Ethical Hacking tutorial part 1 (Footprinting)
Ethical Hacking- Footprinting
Footprinting is a part of reconnaissance process which is used for gathering possible information about a target computer system or network. Footprinting could be both passive and active. Reviewing a company’s website is an example of passive footprinting, whereas attempting to gain access to sensitive information through social engineering is an example of active information gathering.
Footprinting is basically the first step where hacker gathers as much as information as possible to find ways to intrude into a target system or at least decide what type of attacks will be more suitable for the target. During this phase, the hacker can collect the following information –
- Domain name
- IP Addresses
- Employee information
- Phone numbers
- Job information
Below we will discuss how to extract the basic and easily accessible information about any computer system or network that is linked to the internet.
Domain Name information
You can use HTTP:\\www.whois.com/whois website to get detailed information about a domain name. And including its owner, its registration, date of registration, expiry, name, server, owner’s contact information, etc.
Below shows the Domain information about www.google.com.
And domain name profile must be private. One which should hide the above-mentioned information from potential hackers.
Finding IP Address
You can use ping command at your prompt. This command is available on Windows as well as on Linux OS. Following is an example to find out the IP address of google.com
History of websites
It is very easy to get a complete history of any website using www.archive.org.
You can enter a domain name in the search box to find out how the website was looking at a given point in time and what were the pages available on the website on different dates.
Though there are some advantages of keeping your website in an archive database, if you do not like to see how your website progressed through different stages, then you can request archive.org to delete the history of your website.
