Hackers are crazy and like to do things that can be repeated. When a hacker
compromises a system, he tries to expand the time he spends therewith
using tools called rootkits. Rootkits are hackers'
tools and will delete
everything or footprints that he leaves while hacking effectively. Apart from
this hacker also has a fudge to get access as many systems as possible. For
this character trait, they usually try to get access to /etc folder and access all
the user passwords that are present. Rootkits will help the hacker in
extending his connection or relation with the system in a definite way.
If the hacker is gaining money with this method, he may get accustomed to
the fact that many are trying the same. So,
he will make sure that the
vulnerability he has found is not available to anyone. For this reason, he
makes shell scripting code that will spoof the other attackers and make
them not access the system. Hackers also in this process exploit as much as
they can and will back up important files or sensitive information into their
directory using network packeting tools and delete those traces forever.
6) Creating Backdoors in the System
After getting access to a system for a long time and understanding every
pathway and directory system intelligent hackers create backdoors to
continue their exploitation even if the vulnerability is patched. It is often
difficult for security administrators to determine a backdoor until it causes
system damage because they are often cleverly inserted into the system by
hackers.
In this section, we will discuss backdoor and how to make one.
How to make a backdoor:
1) First of all, look at the system as you are in-depth and try to change the
system code in a way such that you can easily get access to the system for
the next time.
2) Backdoor injection tools will have the ability to send the password
changing information using its exploitation tools that are present.
3) Backdoors can also be created in a clumsy manner and of a lot of
variables with weird names so that the programmers can never detect the
original attacker. This anti-spoofing mechanism will lead to a change of the
system code which will be easily obtained by
the hacker using the other
backdoors he has implemented.
By this, we have given a complete tour of how a hacker's mind works. It
may feel overwhelming sometimes, but hackers work it out in a hard way.
So, if you want to be a professional hacker you need to create your working
process or follow this straightforward methodology that has been said by
many famous hackers .
In the next section, we will discuss the
ethical hacking toolkit or
prerequisites a hacker should be aware of before starting web hacking and
network hacking for testing the quality of the systems. Follow along with
this checklist and use it whenever you are starting an attack.
