The 15 Most Infamous Hackers Of All Time
There was a time when hacking was just considered “cool,” but as more and more segments of the government upgraded to computers, hacking has now become a national security threat to countries around the world.
So much so that countries have had to pass legislation to ensure that hackers don’t get out so easy. But of course, finding a hacker isn’t as easy as locating a local criminal. Using multiple ISPs, these hackers can create havoc a million miles away, just by sitting in their bedroom.
Over the last few years, hackers even got glorified thanks to shows like House of Cards and Mr Robot. And why wouldn’t they? It is kind of amazing to think that a bunch of people can hack into someone as powerful as Hillary Clinton’s emails or hack into all the details of the UK government.
The most recent virus, Wanna Cry, attacked thousands of computers in China and Japan. The Russian and American government blamed each other for the virus wave. However, there has been no second wave of attacks.
While most of the current hackers remain anonymous because they want to protect themselves and essentially don’t want to go to jail forever, there are some hackers whose identities have been uncovered over the years.
Here are most infamous hackers of all time:
15. Jonathan James

In 2007, the Boston Market, Barnes & Nobles, and OfficeMax were the victims of another massive attack by him. In May 2008, James was found dead after a self-inflicted gunshot.
14. John McAfee

To get back to the Belize government, McAfee hacked all the computers of their system.

12. John Draper
John Draper, famously known as Captain Crunch, discovered that the whistle found in Cap’n Crunch cereal produced a 26,000 Hertz frequency sound.

John was arrested in 1971 after Esquire published a story about Phone Phreaking. He was sentenced to five years of probation.
The publicity helped Stephen Wozniak to come into contact with the hacker. Steve Jobs and Wozniak eventually hired him to build the telephone interface for the Apple II.
A Greek hacker going by the pseudonym Astra gained excessive fame after he hacked into the French Aviation company Dassault Group’s computers. He stole weapon information for five years before he was found guilty. During this time, Astra sold information about jet fighters and military aircraft to different countries for around $1,000 each.

His real identity has never been revealed, but rumors say that he is a 58-year-old mathematician. Astra was arrested in January 2008 and sentenced to six years in jail.
10. Stephen Wozniak
We all know Wozniak founded Apple along with Steve Jobs. While Stephen was studying at the University of California, he made devices called blue boxes, which enabled free long-distance phone calls. Wozniak was so excited about the new technology that he even used these blue boxes to call the Pope. And this was the first official phone phreaking case.
Taking the help of John Draper, who already had a lot of knowledge about phone systems and phreaking, Wozniak was also able to build the telephone interface for the Apple II computer.
