When a cyber security researcher stopped the spread of WannaCry, the headlines praised him as a savior. But just a few short months later he was in handcuffs for allegedly creating a piece of malware that steals banking information. Even if he is innocent, it’s important to understand the difference between white hat, black hat and even gray hat hackers.
A complicated history
Since all the way back in the 1950s, the term hacker has been vaguely defined. As computers and the people who worked with them became more accessible, the word was used to describe someone who explored the details and limits of technology by testing them from a variety of angles.
But by the 1980s, hackers became associated with teenagers who were being caught breaking into government computer systems. Partially because that is what they called themselves, and partially because the word hacker has an inherently aggressive ring to it.
Today, several of those pioneering hackers run multimillion-dollar cyber security consulting businesses. So what should you call someone who uses their knowledge for good?
“White hat” hackers
Sometimes referred to as ethical hackers, or plain old network security specialists, these are the good guys. Whether it’s selling what they find to hardware and software vendors in “bug bounty” programs or working as full-time technicians, white hat hackers are just interested in making an honest buck.
Linus Torvalds is a great example of a white hat hacker. After years of experimenting with the operating system on his computer, he finally released Linux, a secure open-source operating system.
“Black hat” hackers
Closer to the definition that most people outside the IT world know and use, black hat hackers create programs and campaigns solely for causing damage. This may be anything from financial harm in the form of ransomware to digital vandalism.
Albert Gonzalez is one of the many poster children for black hat hacking. In 2005, he organised a group of individuals to compromise poorly secured wireless networks and steal information. He is most famous for stealing over 90 million credit and debit card numbers from TJ Maxx over the course of two years.
“Gray hat” hackers
Whether someone is a security specialist or a cyber criminal, the majority of their work is usually conducted over the internet. This anonymity affords them opportunities to try their hand at both white hat and black hat hacking.
Today, there are quite a few headlines making the rounds describing Marcus Hutchins as a gray hat hacker. Hutchins became an overnight superstar earlier this year when he poked and prodded the WannaCry ransomware until he found a way to stop it.
During the day, Hutchins works for the Kryptos Logic cybersecurity firm, but the US government believes he spent his free time creating the Kronos banking malware. He has been arrested and branded a “gray hat” hacker.
The world of cyber security is far more complicated than the stylised hacking in Hollywood movies. Internet-based warfare is not as simple as good guys vs. bad guys, and it certainly doesn’t give small businesses a pass.
