Five white hat hackers

Not all hackers are black. Those hackers who use their own hacking skills to do good deeds are called "white hat hackers", which is somewhat similar to the nature of network security engineers. Ordinary hackers are mostly affiliated with security companies, and make a living by testing the security of computer systems. Stephen Wozniak

Wozniak and Steve Jobs are the co-founders of Apple. His hacking trip also originated from stealing free phones.

He dropped out of school to be Apple's first PC with Jobs. At that time, a total of 100 first-generation Macs were produced, each of which cost $666.66.

At present, Wozniak has washed his hands and focused on charity. Tim Berners - Lee

Tim Berners Lee is the father of the Internet. When he was a student at Oxford University, he began to attack with his peers. After that, he was banned from touching the computer by the school.

He unconsciously combined hypertext with TCP and DNS, gave birth to WWW, and then established W3C. Linus Torvalds of MIT.

Linus Torvalds is the founder of ——Linux, the best Unix-like system.

199 1 year, based on Minix operating system, he wrote the kernel of Linux and invited programmers to improve the code together. Now, only 2% of the code in Linux is written by Linus himself.

Because of his outstanding work, he was awarded honorary doctorates by Stockholm University and Helsinki University, and Time magazine listed him as one of the most influential figures in the past 60 years. Richard Stallman

Storman started the GNU project in 1983 to develop a completely free operating system. When he was still working at MIT, people asked them to add passwords to computers. He and other hackers thought that the password system was a means for system administrators to control users. So later he cracked the user's password, and then sent them an email telling them that he cracked their password and told them that it was better to use the Enter key as the password like him, which was shorter and more convenient. This implicitly tells them that the so-called security is just a joke.

Another request to modify the source code of the printer program was rejected, which strengthened his belief in taking the road of free software. Currently active in various anti-monopoly activities. Tsutomu Shimomura

Tsutomu Shimomura's fame benefited from an attack by Kevin Mitnick, a famous black hat hacker.

Japanese-American security experts found the exact location of mitnick. He co-authored a book with John Markoff, a journalist from The New York Times, entitled "Documentary: Chasing the Most Wanted Computer Man in the United States-Narration of the Chaser".
