Who are the Professional Ethical Hackers?
Introduction:
The Impact of Computers and the Internet on the Workplace:
The Rise of Data Theft. The widespread use of computers has transformed the work environment globally, with a shift from physical records to digital storage.
While this has eased the workload of many, it has also heightened the risk of data theft. Hackers, individuals with technical expertise and malicious intent, pose a threat to computer systems and data. Let's examine the different types of hackers and the methods and techniques used in hacker attacks. In a September 2018 survey of U.S. adults, 32.7 percent of respondents stated that they had experienced a hack of their social media or e-mail account. In another survey conducted during the same year, 14 percent of respondents stated that their online accounts had been hacked more than once.
Who is a Hacker?
A hacker is an IT professional who uses technical skills to solve problems or achieve objectives within computer systems. In recent times, "hacker" often refers to a security hacker, who seeks to gain unauthorized access to sensitive information. Some hackers use their skills for lawful purposes.
The Process of Hacking | An Explanation:
Hacking involves unauthorized access to devices, networks, or systems by exploiting vulnerabilities. Hackers possess advanced skills in breaching security to take advantage of technical or social weaknesses.
Technical vulnerabilities:
Exploiting Technical Weaknesses:
Skilled hackers take advantage of software vulnerabilities or poor security practices to gain unauthorized access or inject malware, potentially disrupting the entire system.
Manipulating Social Weaknesses:
Types of hackers:
The world's work environment has dramatically changed due to computers and the Internet, with much data now stored electronically. While this shift has reduced the physical strain on workers, it also raises the risk of data theft.
People who steal or harm data are known as hackers, with various types of hacker attacks and techniques. There are three main types of hackers: black hat, white hat, and gray hat. Not all hacking is malicious or illegal, as some hackers (white hats) use their skills for legal purposes.
1- White Hat Hackers | Authorized Hackers | Ethical hackers:
White Hat hackers, also known as ethical hackers, are computer security experts who use their skills to find and fix vulnerabilities in systems before they can be exploited by malicious actors.
They are hired by companies to test their networks and systems for security weaknesses. They use a combination of tools and manual techniques to identify and patch any vulnerabilities, such as vulnerability scanners, network scanners, web application scanners, code reviews, and penetration tests. White hat hackers work closely with system administrators and security experts to ensure that systems are secure and to help make the online world a safer place.
2- Black Hat Hackers | Criminal Hackers:
Black hat hackers are malicious individuals who use their technical skills to gain unauthorized access to systems and networks for personal gain. They often target companies and government organizations to steal confidential data or disrupt operations. They engage in cybercrime (to prevent cyberattacks see this.)activities such as identity theft and selling stolen data. Black hat hackers exploit vulnerabilities by using malware, social engineering, and phishing tactics to steal sensitive information.
Their activities can result in financial losses, damage to reputations, and disruption of operations. To protect against black hat hackers, organizations should implement strong security measures, keep software updated, and monitor suspicious activity. They should also have a comprehensive security policy and employ professionals to prevent these malicious attacks.
3- Grey Hat: “Just for Fun” Hackers:
A grey hat hacker is a hacker who finds vulnerabilities in computer systems for personal enjoyment, without malicious intent like a black hat hacker. They may access systems without permission, but their goal is not to cause harm. Any individual or organization that wants to protect its systems from unauthorized access is at risk.
4- Green Hat: Hackers-in-Training:
A green hat hacker is a novice in the world of hacking, who seeks to learn and improve their skills with the ultimate goal of becoming a full-fledged hacker. They focus on acquiring knowledge from experienced hackers and don't pose a risk to anyone yet. Their main motivation is to learn and gain expertise in cyberattacks.(Areas of Focus in Cybersecurity)
5- Blue Hat: Authorized Software Hackers:
Blue hat hackers are individuals hired by organizations to identify and fix any security vulnerabilities in new software or systems before their official release. Their aim is to ensure the software is secure before it's made available to the public. Criminal hackers are the ones most at risk from blue hat hackers' efforts.
6- Red Hat: Government-Hired Hackers:
Red hat hackers are government-hired individuals tasked with finding and neutralizing black hat hackers. They employ ruthless methods, using similar tactics as black hat hackers, to take them down. The main focus of red hat hackers is to find and disarm black hat hackers. The primary target at risk is black hat hackers.
7- State-Sponsored Hackers | international Threat Prevention:
State-sponsored hackers are individuals employed by government organizations to perform unauthorized access to foreign networks and systems. They are experts in their field, utilizing advanced techniques to breach their targets. The main objective of state-sponsored hackers is typically espionage, though they may also engage in data theft and sabotage.
8- Hacktivists | Politically Motivated Hackers:
Hacktivists are computer hackers who use their technical abilities to support political and social causes. They frequently target government websites, corporate networks, and other organizations with the aim of making a statement. This form of cyber protest, known as hacktivism, can vary from spreading a message to more aggressive acts such as website defacement, data theft, and DDoS attacks.
The term “hacktivism” combines "hack" and "activism" and is a means of cyber protest. These hackers often use their skills to shed light on injustices, promote free speech, and increase awareness of social and political issues. In some cases, they may also access confidential information and disrupt services for their own reasons, driven by strong political convictions and a desire for change.
Noteworthy hacktivist groups include Anonymous, LulzSec, and Telecomix, involved in leaking confidential documents, and website disruption of governments and corporations, among others. The impact of hacktivists can range from being an annoyance to posing a serious security threat to networks and systems.
Though hacktivism can cause substantial harm by stealing sensitive information and disrupting services, it can also create security loopholes for malicious actors. Hence, it is often viewed negatively by governments and organizations, who consider hacktivists as criminals and their activities illegal.
However, some hacktivists defend their actions as a form of civil disobedience. The issue of hacktivism is complex and contentious, but its impact in the fields of technology and politics is undeniable. As the internet evolves, so will the actions of hacktivists, and their impact will continue to be felt.
9- Malicious Insider: Whistleblower Hackers:
Malicious insider hackers, also known as whistleblowers, are individuals who launch a cyberattack from within their own organization. Their motivations may range from personal grudges to uncovering illegal activities. They aim to exploit or reveal confidential information within the organization. Internal executives and business leaders are at the highest risk of being targeted by malicious insider hackers.
