Who doesn't want to be a hacker? We all are so fascinated by the term hacking, isn't it? so let's talk about ethical hacking. it's like being a digital detective in today's super-connected world.

Everything, from our mobile phones to smart TVs, is connected to the internet, making our lives easier but at the same time, riskier too!

But, as they say, "With great power comes great responsibility." Messing up in this digital playground can be a real headache. It might mean losing your hard-earned cash, getting into trouble you didn't ask for, or even facing some serious privacy invasions.

That's why being a cybersecurity pro is so important. It's like having a digital shield that defends us against the bad guys, keeps our info safe, and helps make the online world a better place.

So let's start learning the cybersecurity, I will help you get started with the easiest possible way, with this ethical hacking for absolute beginners.

What is Ethical Hacking?

Ethical Hacking is an act of finding the loopholes, vulnerabilities, to attempt to gain unauthorized access to a system, application, or a device in an authorized manner. In simple words, it's about hacking the systems with permission of the owner.

This is done to test the security of systems and fix the vulnerabilities to prevent any possible attacks that may happen in the future.

Fields in Ethical Hacking

The realm of ethical hacking and cybersecurity is vast and includes specialized fields:

To begin your journey, grasp the basics of Linux (operating systems, file systems), command-line interface (CLI), a programming language (preferably Python or any other scripting language), ciphers, and cryptography.

This beginners guide breaks down each topic in cybersecurity / ethical hacking, providing resource links for self-learning and hands-on practice.

Digital forensics

Digital forensics involves recovering, analyzing, and examining digital device contents, such as mobile phones, hard disks, and memory cards. It plays a vital role in criminal investigations, providing essential evidence for court proceedings.

Digital forensics plays an important role in investing criminal cases and nowadays has become a crucial part of criminal investigation. The devices found at the crime scene are transferred to the digital forensics department for recovering the data, this information is vital for the court proceedings and is used as evidence. These pieces of evidence are crucial for investigations.

Digital forensics is an important field in the cybersecurity landscape. A career in digital forensics offers lucrative job opportunities, with salaries ranging from 5L to 20L minimum in India. To excel in this field, you need:

  • Attention to detail
  • in-depth knowledge of computer hardware/software
  • Knowledge of various technologies
  • Networking concepts
  • Cyber-security concepts
  • Ready to learn new tools/skills

Reverse Engineering

Reverse engineering is a process of understanding how a device or a system is constructed by means of software as well as hardware. It is a way of identifying the internals of a system and backtracking to recreate it, by analyzing its processes or flow.

It’s also known as backward engineering or back engineering. Furthermore, it enables us to find out how a system or a particular device works so that we can create an updated or improved version of it, use our own system to fill the necessary gaps or create a modified system with the functionality to work for our intended task.

In the cyber-security world, reverse engineering is used to analyze malware or viruses and to find out how they work. It is often used to create the tools to patch the damage caused by the malware or neutralize the malware. It’s also used to find vulnerabilities in software/apps.

To get started with reverse engineering, these skills are required:

  • Proficiency with debugging tools
  • Understanding of Operating systems, CPU architecture and platforms
  • Familiarity of tools like hex editors, disassemblers, debuggers and compilers
  • Programming language as well as understanding of assembly language is a must
  • Understanding of executable file formats, their basics
  • concepts like obfuscation

Binary Exploitation

binary exploitation

Binary exploitation is an act of using the security loopholes/vulnerabilities in a software or system to manipulate the software to perform unauthorized actions or that are not normally allowed for the specific user/role.

Binary exploitation is used to manipulate the software to perform actions it was not designed to do. These loopholes are used to take control of the system and acquire the shell/perform unauthorized activities.

Binary exploitation plays a vital role in cyber security, to master the binary exploitation, one should have these skills:

  • Familiarity with Linux operating systems and command-line interfaces
  • Understanding of Programs/Softwares, Operating systems
  • Understanding of CPU Registers, CPU architecture
  • Knowledge of a scripting language or C
  • Understanding of tools like hex dump, hex editors, file command, strings command

Website hacking

Here comes the interesting part, Website Hacking. it it the most hyped field in cyber security, the hacking scenes in movies.

Website hacking is an act of manipulating or accessing the contents of a website in an unauthorized manner. Website hacking is used to access credentials, and sensitive information of a website and its users, or to stop/block its services of it. It also involves changing the contents of the website and acting on behalf of the users.

Website hacking is commonly done by XSS or cross-site scripting, SQL Injection, Brute Force attacks, Hacking admin panels, Dictionary attacks, Denial of service attacks and more.

To learn website hacking, the following skills are essential.

  • Understanding of web technologies
  • Knowledge of various databases and their types
  • Proficiency in Linux CLI
  • Social Engineering skills
  • Scripting language knowledge
  • Networking concepts
  • Web servers
  • TCP/UPD protocols, ports

Penetration testing

Penetration testing are the activities performed to find out the security vulnerabilities in software/systems and exploit them, penetration testing is performed by ethical hackers and these are authorized cyberattacks on the system to find out the weak points in the system to prevent the loss that may happen by the actual attacks, it is also called as pentest in short.

Penetration testing is useful for assessing the security of an organization, penetration testers use the same tools, techniques and processes as that of an attacker, thus to find out the weaknesses in the system, and performing pen tests helps reduce the risk of data breach from exploiting these vulnerabilities and validate system security.

To learn Penetration Testing, you need:

  • Networking skills
  • Proficiency in Linux and CLI
  • Knowledge of wireless networks
  • Understanding of system administration
  • Familiarity with network services, protocols, and types
  • Knowledge of Active Directory
  • Strong Attention to detail


Cryptography is the branch of cyber-security that deals with hiding or converting information so that no unauthorized person can read it.

Cryptography is a way of securing sensitive information using a set of mathematical rules, and formulae to convert the information in a format that only the intended receiver can retrieve the original contents of the information.

Cryptography is used while storing and transmitting information in a secure communication system, so that no third party, unauthorized user can read the original information, only the receiver with the particular secret key can process the information and retrieve it back.

You need to have following skills to master the cryptography

  • Strong mathematical skills
  • Knolwedge of any programming language, python preferred
  • Number Theory and Number Systems (binary, octal, decimal, hexadecimal)
  • Understanding of Encryption standards
  • Ready to learn tools and write own decryption algorithms

Steganography is a set of techniques used to hide the secret data inside the general non-secret files. the information is hidden in images, audio, video files, these files works normally so one cannot detect that there's something inside these files normally.

Steganograhy is generally performed on image files, zip files, pdf files, audio/video files.
