What is a Hacker?

Introduction

The term “hacker” can have different meanings depending on the context in which it is used. Sometimes, a hacker is a computer expert who uses their technical knowledge to solve problems or create new programs. This type of hacker is often called a “white hat” because they use their skills for good.

However, in other cases, the term “hacker” refers to someone using their computer skills to gain unauthorized access to computer systems or networks. This type of hacker is often called a “black hat” because they use their skills for malicious purposes.

Overall, the term “hacker” can refer to either a skilled computer expert who uses their knowledge for good or someone who uses their skills to gain unauthorized access to computer systems. The specific meaning of the term depends on the context in which it is used.

Is Hacking Legal?

Whether hacking is legal depends on the specific situation and the laws of the jurisdiction in which the hacking is taking place. In some cases, hacking may be legal if it is performed with the permission of the system owner or network being accessed. For example, if a security consultant is hired by an organization to test the security of their systems, the consultant may be allowed to hack into the systems to identify vulnerabilities.

However, hacking may be illegal in other cases, even if performed with the best intentions. For example, this is typically considered illegal if a person gains unauthorized access to a system or network without the owner’s permission.

In general, it is important to understand the laws and regulations that apply to hacking in your jurisdiction and to obtain the necessary permissions before attempting to hack into any systems or networks. Hacking without the proper permissions can result in legal consequences, even if the intentions are benign.

What Do Real Hackers Do?

Real hackers may do various things for a living, depending on their specific skills and interests. Some real hackers may be employed by organizations to help protect their networks and systems from cyber threats (yes, we are hiring). These hackers may use their skills to test the security of a system, identify vulnerabilities, and develop strategies to prevent unauthorized access.

Other hackers may be independent security consultants or researchers who use their skills to help organizations improve their security posture. They may also participate in hacking competitions or challenges, using their skills to solve problems or complete tasks in a controlled environment. Some make a living out of bug bounty programs.

Bug bounty programs are initiatives in which organizations offer rewards or incentives to individuals who can identify and report vulnerabilities or security flaws in their systems or products. These programs are designed to encourage people to help organizations find and fix vulnerabilities before they can be exploited by malicious hackers.

There are many different bug bounty programs run by a variety of organizations, including technology companies, government agencies, and other organizations. These programs may offer different rewards or incentives and have different participation rules and requirements. There are also  “Bug Bounty as a Service” tools, like Bugcrowd and HackerOne, which pay researchers to find product vulnerabilities.

What Do Hackers Study?

Hackers typically study various topics related to computer science, engineering, and information technology. This may include computer programming, network security, cryptography, and operating systems.

Hackers may also study tools and techniques commonly used in hacking, such as exploits, malware, and other types of attack software. They may also study the tactics and methods other hackers use to understand how these attacks work and how to defend against them.

In addition to technical subjects, hackers may also study social engineering techniques, such as persuasion and manipulation, to better understand how to trick people into revealing sensitive information or granting access to systems.

Here are some of the books we recommend reading to get started with infosec:

Do Hackers Get Punished?

Yes, hackers can be punished if caught and charged with a crime. The specific punishment that a hacker may face can vary depending on the laws of the jurisdiction where the crime was committed, as well as the specific details of the crime.

In many cases, hackers can face significant penalties, including fines, imprisonment, and other forms of punishment. For example, in the United States, the Computer Fraud and Abuse Act (CFAA) provides penalties of up to 20 years in prison for certain hacking crimes.

However, it is important to note that not all hackers are caught and prosecuted. Many hacks go undetected, and the perpetrators may never be identified or punished. Additionally, some hackers may operate from countries where the laws and penalties for hacking are less strict, making it more difficult to prosecute them.

What Was the Biggest Hack of All Time?

It is difficult to determine the biggest hack of all time, as many high-profile hacks have resulted in significant damage and losses. Some of the largest and most well-known hacks include the following:

  1. The WannaCry ransomware attack: In May 2017, a group of hackers launched a ransomware attack that infected more than 200,000 computers in 150 countries. The attack used a vulnerability in the Windows operating system, and resulted in widespread disruptions to businesses and public services. The hackers demanded a ransom in exchange for the decryption keys, but it is unclear how much money they could collect.
  2. The Equifax data breach: In 2017, the credit reporting agency Equifax announced that hackers had gained access to the personal information of 143 million customers, including Social Security numbers, addresses, and birth dates. The breach resulted from a vulnerability in the company’s web application, and it is considered one of the largest data breaches in history.
  3. The OPM data breach: In 2015, the US Office of Personnel Management (OPM) announced that hackers had accessed the personal information of more than 21 million federal employees and contractors. The breach was the result of a series of attacks that had been ongoing for over a year, and it is considered one of the largest breaches of government data in history.
