Hacking—Definition, Types, Security, and More
A commonly used hacking definition is the act of compromising digital devices and networks through unauthorized access to an account or computer system. Hacking is not always a malicious act, but it is most commonly associated with illegal activity and data theft by cyber criminals.
Hacking refers to the misuse of devices like computers, smartphones, tablets, and networks to cause damage to or corrupt systems, gather information on users, steal data and documents, or disrupt data-related activity.
A traditional view of hackers is a lone rogue programmer who is highly skilled in coding and modifying computer software and hardware systems. But this narrow view does not cover the true technical nature of hacking. Hackers are increasingly growing in sophistication, using stealthy attack methods designed to go completely unnoticed by cybersecurity software and IT teams. They are also highly skilled in creating attack vectors that trick users into opening malicious attachments or links and freely giving up their sensitive personal data.
As a result, modern-day hacking involves far more than just an angry kid in their bedroom. It is a multibillion-dollar industry with extremely sophisticated and successful techniques.
History of Hacking/Hackers
Hacking first appeared as a term in the 1970s but became more popular through the next decade. An article in a 1980 edition of Psychology Today ran the headline “The Hacker Papers” in an exploration of computer usage's addictive nature. Two years later, two movies, Tron and WarGames, were released, in which the lead characters set about hacking into computer systems, which introduced the concept of hacking to a wide audience and as a potential national security risk.
Sure enough, later that year, a group of teenagers cracked the computer systems of major organizations like Los Alamos National Laboratory, Security Pacific Bank, and Sloan-Kettering Cancer Center. A Newsweek article covering the event became the first to use the word “hacker” in the negative light it now holds.
This event also led Congress to pass several bills around computer crimes, but that did not stop the number of high-profile attacks on corporate and government systems. Of course, the concept of hacking has spiraled with the release of the public internet, which has led to far more opportunities and more lucrative rewards for hacking activity. This saw techniques evolve and increase in sophistication and gave birth to a wide range of types of hacking and hackers.
Types of Hacking/Hackers
There are typically four key drivers that lead to bad actors hacking websites or systems: (1) financial gain through the theft of credit card details or by defrauding financial services, (2) corporate espionage, (3) to gain notoriety or respect for their hacking talents, and (4) state-sponsored hacking that aims to steal business information and national intelligence. On top of that, there are politically motivated hackers—or hacktivists—who aim to raise public attention by leaking sensitive information, such as Anonymous, LulzSec, and WikiLeaks.
A few of the most common types of hackers that carry out these activities involve:
Black Hat Hackers
Black hat hackers are the "bad guys" of the hacking scene. They go out of their way to discover vulnerabilities in computer systems and software to exploit them for financial gain or for more malicious purposes, such as to gain reputation, carry out corporate espionage, or as part of a nation-state hacking campaign.
These individuals’ actions can inflict serious damage on both computer users and the organizations they work for. They can steal sensitive personal information, compromise computer and financial systems, and alter or take down the functionality of websites and critical networks.
White Hat Hackers
White hat hackers can be seen as the “good guys” who attempt to prevent the success of black hat hackers through proactive hacking. They use their technical skills to break into systems to assess and test the level of network security, also known as ethical hacking. This helps expose vulnerabilities in systems before black hat hackers can detect and exploit them.
The techniques white hat hackers use are similar to or even identical to those of black hat hackers, but these individuals are hired by organizations to test and discover potential holes in their security defenses.
Grey Hat Hackers
Grey hat hackers sit somewhere between the good and the bad guys. Unlike black hat hackers, they attempt to violate standards and principles but without intending to do harm or gain financially. Their actions are typically carried out for the common good. For example, they may exploit a vulnerability to raise awareness that it exists, but unlike white hat hackers, they do so publicly. This alerts malicious actors to the existence of the vulnerability.
Prevention from Getting Hacked
There are several key steps and best practices that organizations and users can follow to ensure they limit their chances of getting hacked.
Hackers are constantly on the lookout for vulnerabilities or holes in security that have not been seen or patched. Therefore, updating software and operating systems are both crucial to preventing users and organizations from getting hacked. They must enable automatic updates and ensure the latest software version is always installed on all of their devices and programs.
Use Unique Passwords for Different Accounts
Weak passwords or account credentials and poor password practices are the most common cause of data breaches and cyberattacks. It is vital to not only use strong passwords that are difficult for hackers to crack but also to never use the same password for different accounts. Using unique passwords is crucial to limiting hackers’ effectiveness.
Spoofed websites are another common vehicle for data theft, when hackers create a scam website that looks legitimate but will actually steal the credentials that users enter. It is important to look for the Hypertext Transfer Protocol Secure (HTTPS) prefix at the start of a web address. For example: https://www.fortinet.com.
Avoid Clicking on Ads or Strange Links
Advertisements like pop-up ads are also widely used by hackers. When clicked, they lead the user to inadvertently download malware or spyware onto their device. Links should be treated carefully, and strange links within email messages or on social media, in particular, should never be clicked. These can be used by hackers to install malware on a device or lead users to spoofed websites.
Change the Default Username and Password on Your Router and Smart Devices
Routers and smart devices come with default usernames and passwords. However, as providers ship millions of devices, there is a risk that the credentials are not unique, which heightens the chances of hackers breaking into them. It is best practice to set a unique username and password combination for these types of devices.
What is Ethical Hacking? How Legal is Ethical Hacking?
Ethical hacking refers to the actions carried out by white hat security hackers. It involves gaining access to computer systems and networks to test for potential vulnerabilities, and then fixing any identified weaknesses. Using these technical skills for ethical hacking purposes is legal, provided the individual has written permission from the system or network owner, protects the organization’s privacy, and reports all weaknesses they find to the organization and its vendors.

Hacking is the act of compromising digital devices and networks by gaining unauthorized access to an account or computer system.
What are the seven types of hackers?
There are many different types of hackers, the most common of which are black, grey, and white hat hackers. Black hat hackers are the bad guys—the cyber criminals. The white hat or ethical hackers are the good guys, while grey hat hackers are somewhere in the middle.
Other common hacker types include blue hat hackers, which are amateur hackers who carry out malicious acts like revenge attacks, red hat hackers, who search for black hat hackers to prevent their attacks, and green hat hackers, who want to learn about and observe hacking techniques on hacking forums.
Other common hacker types are cyber terrorists, hacktivists, state- or nation-sponsored hackers, script kiddies, malicious insiders, and elite hackers.
What is the biggest hack in history?
The biggest hack in history is thought to be the data breach against Yahoo! The 2013 attack compromised around 3 billion people, and the company revealed that every Yahoo! customer was affected by it.
Which country has the most hackers?
China is believed to be the country with the highest number of dangerous hackers. Most of the major cyberattacks that occurred around the world can be traced back to China.
