Ethical Hacking 101: Get to Know the Top 5 White Hat Hackers of All Time
What do you think about after hearing the word "hacker"? For many, the term has become painfully associated with digital crime and the illegal actions of cyber threat actors. Truthfully, though, there are tons of ethical hackers out there who put their information security expertise to work to make our world safer and more secure. Initially, terms like a hacker, cracker, and phreaker or hacking, cracking, and phreaking described individuals and actions involving using advanced computer science, network security, and knowledge about telecommunications infrastructure to complete various objectives. Criminals have given the words somewhat of a negative connotation there, and this isn't entirely fair. Throughout the world, ethical hackers are employed in governments, deployed in private organizations, and working to help secure digital assets and infrastructure against the intrusion and encroachment of would-be criminals and state-sanctioned cyber exploitation efforts. These individuals and the organizations they serve are often known as "white hats" and "white hat hackers." Though many do not agree with this somewhat simplistic and dualistic way of thinking, for better or worse, these terms contrast with the idea of "black hats" and "black hat hackers" that use their cyber expertise for less honorable purposes. Though there are many symbolic connections to other topics, these ideas of white and black being in opposition are a timeless convention. Just as in the medieval world, white knights and black knights opposed each other on fields of battle and war. They were divided by their ideologies and attitudes towards personal responsibility. Today's white hat hackers and black hat hackers often find themselves eye to eye in a constant struggle for cyber supremacy and control of the digital networks that have become central to modern human existence. This article outlines the top five most famous ethical hackers of all time. It provides praise for their historic efforts to enhance global cybersecurity and digital resilience to exploitation and crime.

White, Black, Grey, Blue, Green, and Red: Hackers Come in Many Colors
Now that we've set the stage, it's time to introduce some of the other leading players in the fast-paced hacking world. In addition to the terms white and black hats, various other color-based terms that specific global information security or cybersecurity world members have adopted to describe the motivations that drive professionals with these unique and highly in-demand skill sets. White Hat Hackers: This term refers to ethical hackers that use their cyber expertise to complete operations such as penetration tests on banking software to help secure it and prevent criminals from taking advantage of security shortfalls. White hat hackers come in all shapes, sizes, and creeds and can be found in every nation. What aligns a white hat hacker is their decision to use their talents to enhance cybersecurity rather than corrupt it or take advantage of opportunities to be found across networks to exploit, disadvantage, or harm individuals and other organizations. Black Hat Hackers: This term refers to unethical hackers that use their cyber expertise to complete operations. That includes directing a ransomware attack against a bank to plunder cash and cause general chaos. Black hat hackers also come in all shapes and sizes and belong to every nation. Many black hat hackers are also connected to various world governments and might conduct intelligence and war-fighting missions. Black hat hackers use their talents to penetrate networks to exact revenge, create chaos, profit, and harm individuals and organizations. Grey Hat Hackers: This term refers to ethically neutral hackers that may penetrate cyber networks but without the intention of causing harm. Many individuals who become white and black hat hackers begin as grey hats, simply testing out their expertise and advancing their skills by getting online and seeing what is possible. Grey hats are often earlier in their careers and are hungry for knowledge. In some situations, though, grey hats can be at risk of committing severe cyber offenses because of trying to satisfy their curiosity to learn. Red Hat Hackers: This term refers to some of the most hardcore ethical hackers out there. Red hat hackers use their skills to go head to head against black hat hackers. They know that fighting a fire sometimes takes fire. They also understand that to understand their adversaries fully, they must learn to think as they do and act using the same tools and trade secrets. These white hats sometimes use heavy-handed tactics to accomplish their goals in the name of security for both private organizations and national governments. Blue Hat Hackers: This term refers to amateur hacking enthusiasts motivated to advance their skills to exact revenge against individuals and organizations they feel have harmed them in the past. In this way, blue hat hackers could be said to be turning more closely to the dark side of the force but have not entirely made the conversion to a complete Sith Lord just yet. Green Hat Hackers: This term refers to amateur hacking enthusiasts motivated to learn and advance their skills. These hackers are not explicitly motivated by revenge or the desire to harm anyone. They also have not fully learned how to use force for the sake of good. They are interested in learning about hacking and its unique moral opportunities.
