Ethical Hacking (basic)
What is hacking?
Hacking is the act of finding the possible entry
points that exist in a computer system or computer network and finally entering
into them. hacking is usually done to gain unauthorized access to a computer
system or a computer network, either to harm the system or to steal sensitive
information available on the computer. Hacking is not always a malicious
activity, but the term has mostly negative connotations due to its association
with cybercrime. hacking is usually legal as long as it is being done to find
weaknesses in a computer or network system for testing purposes.
Types of hacking (BASIC)
we can segregate hacking into different categories, based on what
is being hacked.
here is a set of basic hacking examples:
Social engineering
Social engineering is a manipulation technique. Using
a fake identity and various psychological tricks, hackers can deceive you into
disclosing personal or financial information. They rely on phishing scams, spam
emails or instant messages, or even fake websites to achieve hacking.
Hacking passwords
Hackers use many ways to gain passwords. The
trial-and-error method in which involves hackers trying to guess every possible
combination to obtain access. Hackers also use simple algorithms to generate
different combinations for letters, numbers, and symbols to help them identify
password combinations. Another technique is known as a dictionary attack, which
is a program that inserts common words into password fields to see if one
works.
Malware hacking
Hackers infiltrate
a user’s device to install malware. More likely, hackers will target potential
victims via email, instant messages, and websites with downloadable content or
peer-to-peer networks.
Wireless Networks Hacking
hackers just
simply take advantage of open wireless networks. Many people do not secure
their Wi-Fi routers, and this can be exploited by hackers driving around looking
for open and unsecured wireless connections. This is an activity known as wardriving.
When hackers are connected to an unsecured network, they only need to
bypass basic security to gain access to devices connected to that network.
Website hacking
Website hacking: hacking a website means taking unauthorized
control over a web server and its associated software such as databases and
other interfaces.
Network hacking
Network hacking a network means gathering
information about a network by using tools like telnet, NS lookup, ping,
tracert, netstat, etc. with the intent to harm the network system and hamper
its operation.
Email hacking
Email hacking includes getting unauthorized access to an email
account and using it without taking the consent of its owner.
The advantages of hacking
are quite valuable for the following scenarios:
Whenever you need to recover lost information, especially in case you lost your
password.
When you want to perform penetration testing to strengthen computer and network
security.
when to put adequate preventative measures in place to prevent security
breaches.
to have a computer system that prevents malicious hackers from
gaining access.
The disadvantages of hacking
are quite dangerous if it is done with harmful intent. it
can cause:
massive security breach.
unauthorized system access to private information.
privacy violation.
hampering system operation.
denial of service attacks
malicious attack on the system.
purpose of hacking
there could be various positive and negative intentions behind
performing hacking activities, here is a list of some probable reasons why
people indulge in hacking activities:
just of fun
show-off
steal important information
damaging the system
hampering privacy
money extortion
system security testing
to break policy compliance
