White-haired 'monsters'

Hackers are not always known as Internet ninjas and are different from the rest of the world. Initially, "hacker" is a word that means positively, to refer to those with extensive knowledge of computers and computer networks. It was not until the Hollywood movies about hackers came into being that the meaning of the word became negative with the default "computer crime expert".

The hacker world is currently divided into two halves: hacker "white hat" and "black hat" hacker. Just as the figurative implies, 'black hat' represents the 'bad' part - is a force of hackers that infiltrate and illegally attack computer systems to harm and profit. 'White hats' represent the rest - are system security experts, or independent 'honest' security researchers.

However, the boundary between the two concepts is quite fragile. Given the need for exploration, discovery, and attraction of money, the 'white hat' hacker will most likely change his life goals, and move from one front line to another. Saying that to see that nothing is clearly different, maybe good people will turn into bad people if they are not steadfast and do not win over themselves in temptation.

However, there are still "white hat" hackers whose work is enough to guarantee their reputation. They know how to combine the passion of research, discovery and fighting against the underground forces that always seek to destroy. In this article, we will return to the original hacker definition and explore the world of white-hat hackers.

1. Tim Berners-Lee

Born on June 8, 1955, also known as TimBL, Tim Berners-Lee is an English computer scientist.

Not only famous for inventing the World Wide Web, Berners-Lee is also known as one of the members of the "white hat" hacker group. As a student at Oxford University, Berners-Lee was banned from using computers at school after he and a friend were arrested for attacks and access to restricted areas.

After finishing college, Berners-Lee also carried out several other attacks, including HTML.

Steve Wozniak is known as a white hat hacker because he created the amazing Blue Box device.

The story begins when Wozniak reads the article that says "The Secret of the Little Green Box", talking about Blue Box. It describes telecom-thieves who hack into the system and make free long-distance calling by using a simulated copy of the audio signal on AT&T network systems. Then they sold blue boxes to their college classmates and friends.

And of course the last part of the story is probably guessing. From that magic box Blue Box they discovered things that were more valuable than it

3. Kevin Mitnick

Mitnick was born on August 6, 1963, originally known as the most famous black hat hacker in the world. After ending a period of multiple attempts to infiltrate the US government's top-secret systems, attacking the world's 'largest' banks and companies, he abandoned the "black hat". "and switched to the work of a writer, a consultant.

In an article on TakeDown.com, it is said that Mitnick's ambition to become a 'hacker' was cultivated very early and he achieved great success.

In 1982, Mitnick was accused of breaking into a North American Air Defense Command computer in Colorado Springs, Colo. He has changed a call program to distract an employee trying to track his call.

4. Tsutomu Shimomura

As a black hat hacker, Mitnick used to hack the system of computer security expert Shimimura. To 'take revenge' on Mitnick's actions, Shimomura took advantage of his 'hacking' skills to help the FBI in tracking and locating Mitnick.

Thanks to Shimomura's help, the FBI succeeded in tracking and locating Mitnick. Mitnick was finally arrested. And now both of them are on the same line.

5. Jeff Moss

Although Moss is known as a white hat hacker, he is known more in the computer world of Dark Tangent.

Moss founded the Black Hat security conferences, and attracted thousands of computer security experts. In addition, he founded Defcon, the annual conference of hackers.

Since he was a child, Torvalds has started to 'hack' important information on his computer. In 1991, inspired by the use of the Mimix operating system, Torvalds created the first Linux kernel version. And soon, Linux has become a popular operating system all over the world to this day.

Although Torvalds was not the first to suggest open-source software, the spread of Linux partly supported the development of open source software.

Torvalds is one of the most influential people in the computer world.

7. Richard Matthew Stallman

Stallman was the one who founded the GNU project. The GNU project includes both open source operating systems and a mass collaboration project.

According to Stallman, GNU includes programs that are not GNU software and these programs have been developed by many different people for their own purposes.

8. Robert Hansen
