All rights reserved. This book will take you through the concepts of computer hacking in a very simple andeasy to follow manner so that even the readers with no prior knowledge of hacking shouldbe able to easily understand the concept. To start off, all you need is a little workingknowledge of computers, operating system Windows and an Internet connection.

Many of the popular books that I have read on ethical hacking are mostly suitable only forthose who already have a considerable amount of knowledge in the field.

Also, thesebooks dive too much into the theory part presenting the reader with lots of unnecessaryexplanation, thereby adding to the bulk of the book. This may cause the reader togradually lose interest in the book or quit reading in the mid way. So, I decided to come up with a book that demands no prior knowledge of the topic and iseasy for the readers to follow and comprehend at every point. Instead of stuffing the bookwith conventional paragraphing kind of content, I prefer to present the topics in an easy tofollow manner by including bullet points, illustrations and practical examples.

I have also decided to drop obsolete concepts and techniques from the bookand only keep those that are active and feasible in the present day scenario. After all, hacking is just a mindset more than a skill set! You should easily be able to protect yourself from all those wicked hackers out there by maintaining the security of your online accounts, web server or your own personal computer.

This book lays the foundation required to start off your career as an ethical hacker where you can begin to apply the knowledge and skills in your profession. This book will cover the concepts of computer hacking for both Windows and Linuxoperating systems.

For Windows based practical examples and illustrations, I have usedmy Windows 8. For Linux based examples I have used Kali Linux 1. Since most examples are not specific of the operating system version, you canimplement them on any version of Windows and Linux installed on your computer. Each chapter including all the concepts presented in this book are laid out in a hierarchical manner where one concept forms the foundation for the other. This may not be true forevery chapter but in many cases the concepts discussed in the earlier part of the book mayseem to form the key elements in understanding the subsequent concepts.

Therefore, Irecommend reading this book in an orderly manner and not skip the concepts or chaptersin between. Throughout this book, you will be presented with many illustrative examples, analogiesand eye-catching diagrams that will not only make the whole understanding processeasier, but also makes the learning process a fun! I hope you like this book and enjoy theconcepts presented in it.

Chapter 1 - Introduction I bet most of you are really excited to get started. But, before we actually move on tolearning how to hack, let us begin to understand what hacking really means. In the field of computer security, hacking simply refers to the act of exploiting theweakness that exists in a computer system or a computer network.

In other works, a hacker is someone who has developed a deeper interest in understandinghow the computer system or the software program works, so that he can take control of thecomputer by exploiting any of the existing vulnerabilities in it.

These type of hackers are often hired by many organizations in order to ensure the security of their information systems. Black Hat Hacker: A black hat hacker also known as cracker is someone who always uses his skills for offensive purposes. The intention of black hat hackers is to gain money or take personal revenge by causing damage to information systems. Grey Hat Hacker: A grey hat hacker is someone who falls in between the white hat and black hat category.

This type of hacker may use his skills both for defensive and offensive purposes. Script Kiddie: A script kiddie is a wannabe hacker. These are the ones who lack the knowledge of how a computer system really works but use ready-made programs, tools and scripts to break into computers.

Exploit: An exploit is a defined way piece of software, set of commands etc.

Buy for others

Threat: A threat is a possible danger that can exploit an existing vulnerability to cause possible harm. Attack: An attack is any action that violates the security of the system. In other words, it is an assault on the system security that is derived from an existing threat.

Hacking is not something that can be mastered overnight. So, for anyone who is wanting to become a hacker, all it takes is some creativity,willingness to learn and perseverance. What skills do I need to become a hacker?

In order to become a hacker, it is essential to have a basic understanding of how acomputer system works.

For example, you may start off with basics of operating system,computer networks and some programming. At this point in time, you need not worry much about this question as this book will takeyou through all those necessary concepts to establish the skills that you need to possess asa hacker. What is the best way to learn hacking? As said earlier, the best way to learn hacking is to start off with the basics. Once you haveestablished the basic skills, you can take it even further by going through the books thatdiscuss individual topics in a much detailed fashion.

Do not forget the power of Internetwhen it comes to acquiring and expanding your knowledge. Chapter 2 - Essential Concepts Now, let us begin to understand some of the basic concepts that are essential in laying thegroundwork for our journey of learning how to hack.

How To Hack: Hacking Secrets Exposed (A Beginner's Guide)

Before actually jumping into thehands-on approach, it is highly necessary for one to have a thorough understanding of thebasics of computer network and their working model. In this chapter you will find a briefdescription of various concepts and terminologies related to computer networks,encryption and security.

Some of the commontypes of computer network include: Local Area Network LAN This is a type of computer network where interconnected computers are situated veryclose to each other say for example, inside the same building. Wide Area Network WAN This is a type of computer network where interconnected computers are separated by alarge distance a few km to few hundreds of km and are connected using telephone linesor radio waves. It is aglobal system of various interconnected computer networks belonging to government orprivate organizations.

This computer can be a terminal or a web serveroffering services to its clients. For example, twocomputers on a network can communicate only if they agree to follow the protocols. The following are some of the most widely referred network protocols: Internet Protocol IP Address An Internet Protocol address IP address is a unique number assigned to each computeror device such as printer so that each of them can be uniquely identified on the network.

A typical example of private IP address would be somethinglike An example public IP address would be something like Once acomputer is on the ISP network it will be assigned a public IP address using which thecommunication with the Internet is made possible. Finding your public IP is extremely simple.

Figure 2. It is one of the most widely used protocol on the Internet forrequesting documents such as web pages and images.

Most e-mail systems that send mail over the Internet use SMTP toexchange messages between the server. TelnetTelnet is a network protocol that allows you to connect to remote hosts on the Internet oron a local network.

It requires a telnet client software to implement the protocol usingwhich the connection is established with the remote computer. In most cases telnet requires you to have a username and a password to establishconnection with the remote host. Occasionally, some hosts also allow users to make connection as a guest or public. After the connection is made, one can use text based commands to communicate with theremote host.

However, SSH has an upper hand over telnet in terms of security. Telnetwas primarily designed to operate within the local network and hence does not take care ofsecurity. On the other hand SSH manages to offer total security while connecting toremote hosts on a remote network or Internet.

Akin to telnet SSH also uses a client software and requires a username and password toestablish connection with the remote host. Each of these services are uniquely identified by a number called network port or simply referred to as port. If a computer wants to avail a specific service from anothercomputer, it has to establish a connection to it on the exact port number where theintended service is running.

For example, if a terminal is to request a web document from a remote server using HTTP,it has to first establish a connection with the remote server on port 80 HTTP service runson port 80 before placing the request. In simple words, port numbers can be compared to door numbers where each door grantsaccess to a specific service on a computer.

When data such as a mail, message or afile has to be transmitted between two hosts, it is fragmented into small structures calledpackets and are reassembled at the destination to make the original data chunk. Since Internet is the mother of millions of computers each having a unique IP address, itbecomes impossible for people to remember the IP address of each and every computerthey want to access.

So, in order to make this process simpler the concept of domainnames was introduced. However, since the network protocol understands only the IP address and not the domainnames, it is necessary to translate the domain name back to its corresponding IP addressbefore establishing a connection with the target server.

This is where DNS comes inhandy. All this processwill happen in a split second behind the scenes and hence goes unnoticed. How DNS Works? This request is oftenreferred to as a DNS query. The local name server will receive the query to find out whether it contains the matchingname and IP address in its database. If found, the corresponding IP address response isreturned. This process continues until the query reaches theDNS server that contains the matching name and IP address.

The IP address response then flows back the chain in the reverse order to your computer. The following figure 2. A firewall can be simply compared to a security guard who stands at theentrance of your house and filters the visitors coming to your place. He may allow somevisitors to enter while deny others whom he suspects of being intruders. Similarly afirewall is a software program or a hardware device that filters the information packets coming through the Internet to your personal computer or a computer network.

How Firewall Works? Firewalls may decide to allow or block network traffic between devices based on the rulesthat are pre-configured or set by the firewall administrator. Most personal firewalls such asWindows firewall operate on a set of pre-configured rules which are most suitable undernormal circumstances, so that the user need not worry much about configuring thefirewall.

The operation of firewall is illustrated in the below figure 2. However, in order to meet customized needs large networks andcompanies prefer those firewalls that have plenty of options to configure. For example, a company may set up different firewall rules for FTP servers, telnetservers and web servers. In addition, the company can even control how the employeesconnect to the Internet by blocking access to certain websites and restricting the transfer offiles to other networks.

Thus, in addition to security, a firewall can give the company atremendous control over how people use their network. Firewalls use one or more of the following methods to control the incoming and outgoingtraffic in a network: 1. Packet Filtering: In this method, packets small chunks of data are analyzed against a set of filters. Packet filters has a set of rules that come with accept and deny actions which are pre-configured or can be configured manually by the firewall administrator.

If the packet manages to make it through these filters then it is allowed to reach the destination; otherwise it is discarded. Instead, it compares certain key aspects of each packet to a database of trusted source. Both incoming and outgoing packets are compared against this database and if the comparison yields a reasonable match, then the packets are allowed to travel further.

Otherwise they are discarded. Firewall Configuration:Firewalls can be configured by adding one or more filters based on several conditions asmentioned below: 1. IP addresses: In any case, if an IP address outside the network is said to be unfavourable, then it is possible to set filter to block all the traffic to and from that IP address.

For example, if a certain IP address is found to be making too many connections to a server, the administrator may decide to block traffic from this IP using the firewall. Domain names: Since it is difficult to remember the IP addresses, it is an easier and smarter way to configure the firewalls by adding filters based on domain names.

By setting up a domain filter, a company may decide to block all access to certain domain names, or may provide access only to a list of selected domain names. Otherwise they are blocked using the firewall so as to prevent intruders from using the open ports for making unauthorized connections. Specific words or phrases: A firewall can be configured to filter one or more specific words or phrases so that both the incoming and outgoing packets are scanned for the words in the filter.

For example, you may set up a firewall rule to filter any packet that contains an offensive term or a phrase that you may decide to block from entering or leaving your network.
