12 Steps To Become A Hacker!

Here we bring to you 12 steps to become a hacker, together with all the books, tutorials and resources that you need to learn in the process. So pack your bags and get set for the journey! 

Hacking is a fascinating field but it definitely isn't easy. Here we have listed 12 of the most important steps essential to become a hacker, together with all the resources that you need for learning. Here we focus on the skills and attitude needed to become a hacker. Breaking the security system and entering into the system is not the only thing a hacker does. One requires knowledge of a wide variety of subjects and in depth knowledge of programming languages and operating systems. And needless to say, learning is essential in the journey...

Here are the 12 steps:

It is not an easy task to become a hacker. As a hacker, you need to have an attitude and curiosity. Reading the hacking manifesto can teach you the attitude of a hacker. Nurturing the hacker attitude is more about developing competence in the languages rather than having a stereotypical attitude.

Though a lot of people consider that a hacker is a criminal, in real life, they are hired by big companies for protecting information and minimizing potential damage. The act of hacking actually is that of being over-curious and outwitting authority. As a hacker, you should be hell bent on breaching authoritarian rules, secrecy and censorship. Deception is another arsenal which will allow you to dodge the vigilant eyes of authority.

The act of stealing something or doing harm to someone is not hacking. Such people are commonly called crackers in the community. Crackers are involved in illegal activities and we do not recommend you to get involved into such activities.

Step 1: Learn To Program In C

C programming is one of the most powerful languages in computer programming. It is necessary to really master this language. This programming language was invented by Denise Ritchie in between the years 1969 and 1973 at AT&T Bell Labs. C programming will essentially help you divide the task in smaller pieces and these pieces can be expressed by a sequence of commands. Try writing some program on your own by assessing the logic.

Here are 35 ebooks on C programming

Step 2: Learn More Than One Programming Language

When you are trying to become a hacker, it is very important to learn other modern computer programming languages such as JAVA, Perl, PHP and Python. One of the best ways to learn these is by reading books from experts.

Here are 32 free ebooks on JAVA

Here are 24 free ebooks on Perl

Here are 21 free ebooks on PHP

Here are 50 free ebooks on Python

Step 3: Learn UNIX

UNIX is a multi-tasking and multi-user computer operating system that is designed to provide good security to the systems. This operating system was developed by some employees of AT&T in Bell Labs. The best way to learn it is to get into an open-source version (e.g. centos) and install/run the same on your own. You can operate internet without learning UNIX, but it is not possible for you to be an internet hacker without understanding UNIX.

Here are 33 free ebooks on UNIX

Step 4: Learn More Than One Operating Systems

There are many other operating systems apart from UNIX. Windows operating system is one of the most commonly compromised systems, hence, it is good to learn hacking Microsoft systems, which are closed-source systems.

According to the National Vulnerability Database, Microsoft operating systems have a large number of vulnerabilities.

Windows OS installers are distributed in binary, therefore, it is not easy for you to read the code. Binary code is basically the digital representation of text and data that computer understands. However, knowing how programs are written for Windows and how different applications behave on this operating system will help.

One of the recent vulnerabilities of a popular OS was that Java Web Start applications get launched automatically even if the Java plug-ins are disabled. How to be a hacker is about knowing the weaknesses of these operating systems and targeting them systematically.

Step 5: Learn Networking Concepts

The networking concept needs to be sharp when you want to be a hacker.

Understanding how the networks are created is important, however, you need to know the differences between different types are networks. Having a clear understanding of TCP/IP and UDP protocol is a must to be able to exploit the vulnerabilities on world wide web.

Understand what is subnet, LAN, WAN and VPN.

The networking commands to do a HTTP request needs to be on your fingertips. The HTTP protocol, is the gateway through which one enters the internet world. Hence, it is necessary to learn this protocol in order to break the barriers. The hackers often use the HTTP gateway to breach the security of the system and take control over it.

Apache Httpd is one of the most commonly used web servers and knowing in and out of it is going to empower you on any HTTP or other application layer protocol related endeavors.

Also Nmap is a powerful network scanning tool that is used by hackers and security professional across the world to identify vulnerable hosts. However, to effectively start using it you must understand the networking basics.

Step 6: Start Simple: Go Through Tutorials About Hacking

This is the simple and best way to start. Read as many tutorials as possible that are meant for hacking. These articles will give you insight and help you develop the attitude to be a hacker. Some tutorials will initiate you with Nmap, Nessus and SuperScan, some of the hacking programs or tools that hackers generally use. These tutorials are readily available over the internet; Both text and video tutorials are available for you to answer your question how to be a hacker.

Here are some of the video tutorials

Here are some of the text tutorials

Step 7: Learn Cryptography

As an expert hacker, you need to understand and master the art of cryptography. The technology of cryptography and encryption is very important for internet and networking. It is the practice and study of techniques that are used for secure communication in the presence of third parties. The encryption is done for various aspects of information security such as confidentiality of the data, integrity of the data and authentication. Moreover, the technology of cryptography is extensively used in ATM cards, computer passwords and e-commerce. While hacking, these encrypted codes needs to be broken, which is called decryption.

Understand various techniques used for password cracking. There are dozens of tools available to do password cracking, and using it is not hacking. To be expert at hacking its important for you to understand how to create a program that can crack a password from cypher text.

Here are 20 free ebooks on Cryptography

Step 8: Experiment A Lot

This is an important step for setting yourself up as an expert hacker. Setup a laboratory on your own to experiment the learning on the practical applications. A simplest lab will have your computer, however once you advance you may want to add more and more computers and required hardware for your experiments.

It is good to try experimenting on your own computers, where you can rectify if you have done any mistake. Many hackers initially start off by downloading virtual lab applications such as Oracle VirtualBox. You require at least 3 GBs of RAM and a comparatively powerful processor to carry out your hacking experiments. Setting up the virtual machine is crucial, as it will allow you to test virus, applications and different servers without affecting your own PC.

Some of the things you may need to keep in mind when doing experiments

- Keep a backup before any experiment.
- Start small and have check points.
- Know when to stop.
- Document your progress
- Keep improvising
- Automate repetitive tasks

Step 9: Read Some Good Books From Experts

Reading will always enhance your knowledge. Try to read as many books and articles as possible written by the experts in the field field of ethical hacking and enterprise security

Reading a lot about anything related is so important in the world of hacking that you must also consider enhancing your reading speed. If your reading speed is slow, then you may not be able to progress fast in this field. Practice speed reading techniques like skimming, chunk reading etc.

When it comes to reading a lot, it's also important to know that a majority of content on web is not worth your time. Many people use search engine tricks to attract traffic but have little value in it. If you skim through an article within seconds and decide not to read that is going to save you a lot of time for some really well researched content.

Step 10: Go Next Level: Write Vulnerability

Vulnerability of a program is the weakness of the program. It is a good approach to look for the vulnerability of an existing program and share the same with others. In this way you will have the option to collect varied opinions from different sources, enabling you to hone your current skill set.

The examples of computer vulnerabilities include memory safety violation, input validation error, privilege confusion bugs and user interface failure. For instance, Microsoft’s Internet Explorer 11 had the vulnerability bug in its preview version which several hackers exploited.

Identifying a new weakness in any software is the real work any expert hackers would perform.

Step 11: Contribute To Open Source Security Projects

Contributing to an open-source computer security project is a great platform to test your skills. This is not everyone’s cup of tea. Many organizations like Mozilla and Apache offer these types of open source projects. Try to be a part of these projects and add a valuable contribution to the benefit of the community.

Participating in the open source security projects such as anti-spam, anti-virus, firewall and data removals help you augment your dexterity as a hacker. Contribute your vulnerability findings to the global vulnerability databases and give back to the community.

Remember that it does not matter if your contribution is small, as long as you participate and add value it helps.

Step 12: Continue Learning And Keep Listening To Security Talks

The key to success in the hacking career is continuous learning. Reading blogs for hacking available at sites such as hackerfactor blog and IKEA hacker blog; participating in the forums such as hackforums.net and elite hack are great ways to refresh your knowledge as a hacker. The online video forums like TED or TechTalk are good sources to know more about the emergent hacking techniques and technologies that are being deployed. You should also try following the posts of famous hackers such as Adrian Lamo, Kevin Mitnick, Kevin Poulsen and Robert Tappan Morris.

Learn How To Create Animations Without jQuery

JavaScript animation libraries which bypass jQuery actually deliver incredible performance as they avoid DOM manipulation as much as possible. 

A belief is very much present there in the web development community that if you want to make animations on the web, CSS animation is the only way. Hence several developers abandon JavaScript-based animation. But the reality is that JavaScript-based animation is often as fast as CSS-based animation, sometimes it's faster. JavaScript animation libraries which bypass jQuery actually deliver incredible performance as they avoid DOM manipulation as much as possible.

These libraries act 20 times faster than jQuery. So if you want to use JavaScript in your UI animations then go through the following facts and steps:

1. JavaScript Use: 

CSS animations are definitely convenient if you want to sprinkle property transitions into your style sheets. They deliver fantastic performance out of the box. But when you use CSS transitions to power rich motion design it becomes too difficult to manage all the features.

But in JavaScript, you have an infinite amount of logical control. The key features of JavaScript animation are cross-browser SVG support, physics-based loader animations, timeline control and Bezier translations.

2. Velocity and GSAP: 

The two most popular JavaScript animation libraries are Velocity.js and GSAP. These libraries work both with and without jQuery. If they are used with jQuery, then there is no degradation in your performance.

If jQuery is present on your page, you can use Velocity and GSAP just like you would jQuery’s $.animate().

But these two libraries can also work when jQuery is not present on the page. This means you don't need to limit an animation call onto a jQuery element object and you would pass the target element(s) to the animation call by:

/* Working without jQuery */

Velocity(element, { opacity: 0.5 }, 1000); // Velocity

TweenMax.to(element, 1, { opacity: 0.5 }); // GSAP


On the other hand, GSAP uses an object-oriented API design so that you get full control over animations.

3. Working Without jQuery: 

Let’s explore querySelectorAll as it will likely be your best weapon if you are into animation without jQuery:

document.querySelectorAll("body"); // Get the body element
document.querySelectorAll(".squares"); // Get all elements with the "square" class
document.querySelectorAll("div"); // Get all divs
document.querySelectorAll("#main"); // Get the element with an id of "main"
document.querySelectorAll("#main div"); // Get the divs contained by "main"


You can simply pass querySelectorAll a CSS selector (the same selectors you would use in your style sheets), and it will return all matched elements in an array. As you're attaching animations to jQuery element objects, you may be wondering how we can chain animations back to back, like this:

$element // jQuery element object
.velocity({ opacity: 0.5 }, 1000)
.velocity({ opacity: 1 }, 1000);

With Velocity, you can just call animations one after another:

/* These animations automatically chain onto one another. */
Velocity(element, { opacity: 0.5 }, 1000);
Velocity(element, { opacity: 1 }, 1000);


If you're animating this way then there is no chance of any performance drawback. This one-Velocity-call-at-a-time process has a huge benefit too like if you’re using promises with your Velocity animations, then you will get an actionable promise object with each Velocity call. In the case of GSAP, there is an expressive object-oriented API which allows you to place your animations in a timeline. It gives you control over scheduling and synchronization.

Animation is an experimental process and you need to play with timing. While CSS transitions are easy to use, they become unmanageable as soon as you attempt to sequence even moderately complex animations. Velocity has its UI pack designed in a way so that it deals with multi-animation complexity, and GSAP offers nestable timelines.

4. JavaScript Functions: Physics: 

There are several powerful effects which can be achieved exclusively via JavaScript. You can explore the same with physics-based animation. The utility of physics in motion design is that interfaces flow naturally from the user’s input, which means, interfaces adhere to how motion works in the real world.

GSAP offers physics plugins which adapt to the constraints of your UI. Velocity offers an easing type which is based on spring physics. Velocity offers an easing type based on spring physics. With the typical easing options, you pass in a named easing type.

5. JavaScript Functions: Scrolling: 

Velocity enables the user to scroll the browser to the edge of any element by passing in scroll as Velocity’s first argument (instead of a properties map). The scrollcommand behaves in a similar way to a standard Velocity call; options are taken and they can be queued too. Elements can be scrolled within containers and you can scroll horizontally too.

GSAP has ScrollToPlugin and it offers similar functionality. It automatically relinquishes control when the user interacts with the scroll bar.

6. JavaScript Functions: Reverse: 

Velocity and GSAP have reverse commands enabling you to animate an element back to the values prior to its last animation. GSAP enables you to retain a reference to the animation object. Then invoke its reverse()method at any time: var tween = TweenMax.to(element, 1, {opacity:0.5});
tween.reverse();

6. Transform Control: 

CSS animation contains all transform components in a single CSS property including scale, transla-tion, rotation and skew. So it cannot be animated independently using different durations. For rich motion design independent control is imperative. Both Velocity and GSAP allow you to animate transform components individually.

So we can come to this conclusion that JavaScript animation has better browser support and more features in comparison to CSS animation. JavaScript provides a more manageable workflow for animation sequences. Most importantly you don’t need to use jQuery for animation with JavaScript libraries, without affecting performance level.
