What does a Hacker Do?
In simple terms, Hackers are experts skilled at breaching and breaking down the defences of computer systems in order to gain unauthorized access into various electronic devices such as laptops, computers, phones, IoT devices, networks, and even the entire computer systems. Hackers essentially take advantage of cracks and weaknesses that are present in the security systems of a network.
While hackers are often stereotyped as youngsters who are skilled in modifying computer systems and programs, in reality, today’s hacker community comprises various kinds of individuals who have their own motives and goals.
Roles and Responsibilities of a Hacker
The role of a hacker is not merely limited to hacking computer systems and accessing sensitive information. The other responsibilities of a hacker also include:
- An ethical hacker scans systems and networks using various scanning tools such as Nmap and Nessus to find open and vulnerable ports and close them to prevent any potential cyber attacks.
- Ethical Hackers are also responsible for examining patch installations and ensuring they are not vulnerable to any cyber attacks.
- An ethical hacker also makes use of social engineering to search through digital trash bins and other dark corners of the network to find any personal information, passwords, or any other sensitive information that can be used for a cyber attack.
- Hackers also try to evade security systems such as the IDS to avoid any detection. They attempt to fall through the cracks of the security systems undetected.
- Hackers also help in strengthening the security of the network systems and develop preventive measures to reduce the chances of a cyber attack.
- Ethical hackers must also report any kind of security breaches to their superiors and keep any information they have discovered confidential.
- Hackers should also clear their trails or trace after completing a security check-up to prevent malicious hackers from exploiting any loopholes or vulnerabilities.
Types of Hackers
As mentioned earlier, the hacking community comprises individuals with varying motives and goals. The various types of hackers are as follows :
- White Hat Hackers: White Hat Hackers or Ethical Hackers are those professional hackers who do not intend to cause any harm to any computer systems or programs. They closely work with organisations to identify gaps and cracks in their security systems and protect them against cyber attacks.
- Black Hat Hackers: Black Hat Hackers or Crackers are those professional hackers with malicious motives who intend to cause harm to computer systems and programs. They hack into computer systems and networks to access personal and financial data for selfish motives.
- Grey Hat Hackers: Grey Hat Hackers are a combination of White Hat Hackers and Black Hat Hackers. The main motive is to gain unauthorized access into computers systems and networks without any malicious intent. These hackers like cracking systems and exploiting weaknesses in them just for fun.
- Script Kiddies: A script kiddie is an amateur hacker with only basic knowledge of hacking. They usually hack into computer systems and networks with pre-written scripts or codes written by others. They do not have complete knowledge about hacking.
- Hacktivist: Hactivists are activists that intend to hack government websites and networks to gain access to government secrets and expose them to the public. They usually involve DoS attacks or website defacement.
- Green Hat Hackers: Green Hat Hackers or a Neophyte are the ones who are new to the field of hacking. They are beginners who have little to no knowledge of hacking and wish to gain more expertise in this field.
- Red Hat Hackers: Red Hat Hackers are similar to White Hat Hackers except for their methodology. Red Hat Hackers also intend to protect computers systems and networks, however, they are more ruthless while dealing with Black Hat Hackers.
- Blue Hat Hackers: Blue Hat Hackers are similar to Script Kiddies, however they intend to use their knowledge to seek revenge against an organisation or a person. They are also new to the field of hacking and usually have revengeful intentions when they learn hacking.

How to Become a Hacker?
You can find below a comprehension step-by-step guide to begin your journey to becoming a professional hacker :
Earning a Relevant Degree or Certification
Most students who wish to pursue a career in the field of hacking usually complete a bachelor’s degree or a master’s degree in computer science or a related field. They also have the option of obtaining a professional certification that usually requires students to clear two separate exams to become a professional ethical hacker. The CompTIA Security+ certification is a popular certification that students usually opt for when they wish to pursue a career in hacking and cybersecurity. Additionally, students with EC-Council’s Certified Ethical Hacker (C|EH) credential is sought after by many employers who are looking to hire ethical hackers.
Learn the Concepts of Networking
As a hacker, you must be able to grasp the concept of networking and understanding the knowledge behind the creation of networks. Students can also take up an entry-level position as network support to understand essential activities such as the creation of networks, monitoring, updating, and installing the latest security systems, and checking for any vulnerabilities.
Excel in All the Programming Languages
By excelling in the mother of all programming languages, C Programming, students gain the opportunity to learn the basics of UNIX/LINUX since its operating system is written through C programming. Students should excel in at least 2 to 3 programming languages since it gives them the freedom to create their programs and security systems in their own distinct style.
Learn How to Use Linux
Almost all of the best-operating systems for hacking are based on Linux. UNIX/LINUX is an open-source operating system that provides better security to computer systems. Mastering this enables students to become better professional hackers, whether they are freelancers or working in an organization. Almost all professional hackers use UNIX/LINUX systems.
To be a successful hacker, students must also master the art of cryptography since encryption and decryption also form an important part of hacking. Encryption is mostly done for strengthening the security of network and computer systems to ensure confidentiality and integrity of data. Students need to master both aspects of cryptography since decryption is also required to crack codes and decrypt data as and when required.
Joining Formal Hacking Communities
Students also have the excellent opportunity to join legal and formal hacking communities that comprise many professional ethical hackers that can help many beginners to find their foothold when they begin their career in hacking. They can also participate in many discussion forums that are composed of individuals and students from all over the world as well as have the opportunity to be a part of many exciting hacking competitions and contests that allows them to enhance their skills and improve their knowledge and coding skills.
