Are you a beginner who wants to learn hacking but don’t know where to
start? If so you are at the right place. Since most of the books and
free resources on the Internet are only meant for those who already have
a considerable amount of knowledge on the subject, they fail to teach hacking for beginners.
Therefore, I have decided to come up with this post that gives useful
tips for beginners on how to kick start their journey to becoming a
hacker
many subgroups of the computer underground with different attitudes
use different terms to demarcate themselves from each other, or try to
exclude some specific group with which they do not agree. Eric S.
Raymond (author of The New Hacker's Dictionary) advocates that members
of the computer underground should be called crackers. Yet, those people
see themselves as hackers and even try to include the views of Raymond
in what they see as one wider hacker culture, a view harshly rejected by
Raymond himself. Instead of a hacker/cracker dichotomy, they give more
emphasis to a spectrum of different categories, such as white hat, grey
hat, black hat and script kiddie.
A white hat hacker breaks security for non-malicious reasons, perhaps to
test their own security system or while working for a security company
which makes security software. The term "white hat" in Internet slang
refers to an ethical hacker. This classification also includes
individuals who perform penetration tests and vulnerability assessments
within a contractual agreement. The EC-Council , also known as the
International Council of Electronic Commerce Consultants has developed
certifications, course ware, classes, and online training covering the
diverse arena of Ethical Hacking.
A "black hat" hacker is a hacker who "violates computer security for
little reason beyond maliciousness or for personal gain" (Moore, 2005).
Black hat hackers form the stereotypical, illegal hacking groups often
portrayed in popular culture, and are "the epitome of all that the
public fears in a computer criminal". Black hat hackers break into
secure networks to destroy data or make the network unusable for those
who are authorized to use the network.
Part 1: Targeting
The hacker determines what network to break into during this phase. The
target may be of particular interest to the hacker, either politically
or personally, or it may be picked at random. Next, they will port scan a
network to determine if it is vulnerable to attacks, which is just
testing all ports on a host machine for a response. Open ports—those
that do respond—will allow a hacker to access the system.
Part 2: Research and Information Gathering
It is in this stage that the hacker will visit or contact the target in
some way in hopes of finding out vital information that will help them
access the system. The main way that hackers get desired results from
this stage is from "social engineering", which will be explained below.
Aside from social engineering, hackers can also use a technique called
"dumpster diving". Dumpster diving is when a hacker will literally
search through users' garbage in hopes of finding documents that have
been thrown away, which may contain information a hacker can use
directly or indirectly, to help them gain access to a network.
Part 3: Finishing The Attack
This is the stage when the hacker will invade the preliminary target
that he/she was planning to attack or steal. Many "hackers" will be
caught after this point, lured in or grabbed by any data also known as a
honeypot (a trap set up by computer security personnel).
Grey hat:-
A grey hat hacker is a combination of a Black Hat and a White Hat
Hacker. A Grey Hat Hacker may surf the internet and hack into a computer
system for the sole purpose of notifying the administrator that their
system has been hacked, for example. Then they may offer to repair their
system for a small fee.
Elite hacker:-
A social status among hackers, elite is used to describe the most
skilled. Newly discovered exploits will circulate among these hackers.
Elite groups such as Masters of Deception conferred a kind of
credibility on their members.
Script kiddi:-
A script kiddie (or skiddie) is a non-expert who breaks into computer
systems by using pre-packaged automated tools written by others, usually
with little understanding of the underlying concept—hence the term
script (i.e. a prearranged plan or set of activities) kiddie (i.e. kid,
child—an individual lacking knowledge and experience, immature).
Neophyt:-
A neophyte, "n00b", or "newbie" is someone who is new to hacking or
phreaking and has almost no knowledge or experience of the workings of
technology, and hacking.
Blue hat:-
A blue hat hacker is someone outside computer security consulting firms
who is used to bug test a system prior to its launch, looking for
exploits so they can be closed. Microsoft also uses the term BlueHat to
represent a series of security briefing events.
Hacktivis:-
A hacktivist is a hacker who utilizes technology to announce a social,
ideological, religious, or political message. In general, most
hacktivism involves website defacement or denial-of-service attacks.
Nation state Intelligence agencies and cyberwarfare operatives of nation
states.
Attack:-
A typical approach in an attack on Internet-connected system is:
1. Network enumeration: Discovering information about the intended target.
2. Vulnerability analysis: Identifying potential ways of attack.
3. Exploitation: Attempting to compromise the system by employing the vulnerabilities found through the vulnerability analysis.
In order to do so, there are several recurring tools of the trade and
techniques used by computer criminals and security experts.
Security exploit:-
A security exploit is a prepared application that takes advantage of a
known weakness. Common examples of security exploits are SQL injection,
Cross Site Scripting and Cross Site Request Forgery which abuse security
holes that may result from substandard programming practice. Other
exploits would be able to be used through FTP, HTTP, PHP, SSH, Telnet
and some web-pages. These are very common in website/domain hacking.
Techniques
Vulnerability scanner:-
A vulnerability scanner is a tool used to quickly check computers on a
network for known weaknesses.Hackers also commonly use port scanners.
These check to see which ports on a specified computer are "open" or
available to access the computer, and sometimes will detect what program
or service is listening on that port, and its version number. (Note
that firewalls defend computers from intruders by limiting access to
ports/machines both inbound and outbound, but can still be
circumvented.)
Password cracking:-
Password cracking is the process of recovering passwords from data that
has been stored in or transmitted by a computer system. A common
approach is to repeatedly try guesses for the password.
Packet sniffer:-
A packet sniffer is an application that captures data packets, which can
be used to capture passwords and other data in transit over the
network.
Spoofing attack (Phishing):-
A spoofing attack involves one program, system, or website successfully
masquerading as another by falsifying data and thereby being treated as a
trusted system by a user or another program. The purpose of this is
usually to fool programs, systems, or users into revealing confidential
information, such as user names and passwords, to the attacker.
Rootkit:-
A rootkit is designed to conceal the compromise of a computer's
security, and can represent any of a set of programs which work to
subvert control of an operating system from its legitimate operators.
Usually, a rootkit will obscure its installation and attempt to prevent
its removal through a subversion of standard system security. Rootkits
may include replacements for system binaries so that it becomes
impossible for the legitimate user to detect the presence of the
intruder on the system by looking at process tables.
Social engineering:-
When a Hacker, typically a black hat, is in the second stage of the
targeting process, he or she will typically use some social engineering
tactics to get enough information to access the network. A common
practice for hackers who use this technique, is to contact the system
administrator and play the role of a user who cannot get access to his
or her system.
Trojan horses:-
A Trojan horse is a program which seems to be doing one thing, but is
actually doing another. A trojan horse can be used to set up a back door
in a computer system such that the intruder can gain access later. (The
name refers to the horse from the Trojan War, with conceptually similar
function of deceiving defenders into bringing an intruder inside.)
Viruses:-
A virus is a self-replicating program that spreads by inserting copies
of itself into other executable code or documents. Therefore, a computer
virus behaves in a way similar to a biological virus, which spreads by
inserting itself into living cells. While some are harmless or mere
hoaxes most computer viruses are considered malicious.
Worm:-
Like a virus, a worm is also a self-replicating program. A worm differs
from a virus in that it propagates through computer networks without
user intervention. Unlike a virus, it does not need to attach itself to
an existing program. Many people conflate the terms "virus" and "worm",
using them both to describe any self-propagating program.
Key loggers:-
A key logger is a tool designed to record ('log') every keystroke on an
affected machine for later retrieval. Its purpose is usually to allow
the user of this tool to gain access to confidential information typed
on the affected machine, such as a user's password or other private
data. Some key loggers uses virus-, trojan-, and rootkit-like methods to
remain active and hidden. However, some key loggers are used in
legitimate ways and sometimes to even enhance computer security. As an
example, a business might have a key logger on a computer used at a
point of sale and data collected by the key logger could be used for
catching employee fraud.
Learn Programming (Optional)
If you want to take your hacking skills
one step ahead, programming is something that you can’t skip down.
Although you can easily find a lot of ready made tools and programs that
let you hack with ease, it is always better to have some basic
knowledge of programming languages like HTML, PHP and JavsScript so that
you will be in a position to develop your own tools and exploit codes.
However, if you do not wish to learn programming you can skip this step
and still be a good hacker.
How Long does it Take to Master the Skills of Hacking?
Since hacking is not something that can
be mastered overnight, you should never be in a hurry to get going. It
requires knowledge, skills, creativity, dedication and of course the
time. Depending upon the amount of effort and dedication you put, it can
take up anywhere between a few months to few years to develop all the
the necessary skills. Everyone can become a hacker provided they learn
it from the basics and build a solid foundation. So, if you want to be a
hacker all you need is passion to learn, a good source of knowledge
that will guide you through the basics and some perseverance.
Short Bytes: Your desire to master the art of Facebook hacking can harm you in a big way. Recently, a variant of Remtasu malware has been spotted in the wild that can hack your Facebook, instead of your friend’s account. Surprisingly, this malware always finds a way to remain on the system even after the victim reboots the system or tries to locate the threat in the list of active processes.
