In today’s interconnected world, cybersecurity attacks are a common threat all companies face. As more and more companies perform their data operations online, the chances of attacks are increasing rapidly. Hackers are not just becoming more efficient, but are not afraid to target even large organizations with well-equipped security measures.

In 2011, Sony lost around $170 million due to a hacker who hacked into a PlayStation system and stole valuable data. Similarly, in 2018, Marriott International found out that hackers have stolen data of almost 500 million customers. Therefore, IT professionals are opting for an Ethical Hacking course to help their companies fight against security threats.

Let us take a look at the basics of hacking.

What is hacking?

Hacking means accessing a computer or network without permission. The person performing the unauthorized access is called a hacker. Notably, a hacker identifies the technical weaknesses of a computer or a network. He or she then uses this vulnerability to gain access to the system. The main aim of any hacker is to alter the security features of the system.

There are different types of hackers. They are differentiated based on their activities:

Ethical hackers

They are also called White Hat hackers. They identify the weaknesses of computers and networks in order to fix them. Ethical hackers are employed by companies as security professionals to fight against malicious cyber attacks.


They are also called Black Hat hackers as their main intention is to hack into systems and perform malicious activities. They steal customer or business data, transfer funds, and blackmail companies, violate their privacy rights and damage their servers.

Grey hat hackers

This type of hackers falls between White Hat and Black Hat hackers. They might hack into a user’s system to identify the vulnerabilities. Then, they will show these weaknesses to the system user. The user may rectify it to enhance security.


They are a special type of hackers who have a common agenda. They use hacking as a medium to convey a particular religious, social or political message to the people or a government. Usually, they hack into websites and social media accounts to leave a message that can be viewed.

Both small and large companies are vulnerable to cyberattacks. Hackers perform the following attacks and scams to create problems:

Malware attacks

These involve small pieces of code that might arrive in different forms. They may be e-mail attachments and additional software that come with the original software. After installation, they spread to the entire system. Ransomware is an example of malware that denies users access to their sensitive information. Users need to pay a certain ransom amount to regain access. Hackers use this to blackmail companies and extort money in return of user data.


These are ways to steal sensitive information through fake websites. In this process, links are sent to users or employees. They are offered amazing prizes and gifts in order to make them click on a certain link. This link will take them to a fake website that looks exactly similar to an original reputable site, such as Facebook or Gmail. Hackers steal the user information that is logged in. Companies have lost a lot of money and sensitive information over the years due to phishing scams.

Misusing weak passwords

Weak passwords are an easy way to gain access to many user accounts. More than 80% of the system hacks involve password cracking. This is because most people use one password for all of their accounts online. A hacker can use a simple graphics card to run more than 300 billion password combinations per minute. In 2012, hackers cracked more than 1 million eHarmony passwords and 6 million LinkedIn passwords.

DDoS attacks

Distributed denial of service attacks is used to temporarily or permanently disable a company’s server. The hacker floods the server with access requests and data with the help of botnets. Notably, a botnet is an infected computer that is directed to send requests to a specific target such as a server.
