Top 5 Dangerous Hackers In The World

Top 5 Dangerous Hackers In The World

Today, we are going to talk about the Top 5 Dangerous Hackers In The World forever. Computer hacking is the act of identifying and exploiting the system and network vulnerabilities in order to obtain unauthorized access to those systems. The term ‘hacker’ probably appeared in your news feed most of the time last year, for most of the prominent attacks and it’s likely to pop up a lot more. Computers and the Internet have changed the work environment of the world beyond imagination. In the case of computers occupying a large part of our lives, all our data has been transferred to computers and the virtual world. Although such changes reduce physical presence, they also increase the chances of data theft.

There are Mainly Three Types of Hackers we all know: –

  • White Hat Hackers: – A white hat hacker is an ethical computer hacker and a computer security expert who specializes in penetration testing and other testing methods that ensure the security of an organization’s information system. This is an individual person who uses hacking skills to detect security vulnerabilities in hardware, software or networks. White hat hackers also called Ethical Hackers.
  • Black Hat Hackers: – A black hat hacker is a hacker who violates the cyber laws for their own profit. They are the bad guys of the hacker world. Black hat hackers are also knowledgeable computer experts but with the wrong intention. Black hat hackers are actually criminals who enter computer networks with malicious intent and expose malware that destroys files and computer systems. Their main intention is to steal passwords, credit card and bank account numbers, sensitive personal information and blackmailing. Black hat hackers are malicious hackers, sometimes called crackers.
  • Grey hat hackers: – The Gray hat hacker falls in between the black hat hackers and white hat hackers. These types of hackers do not inherently corrupt their motives; they are just looking to get something from their own discovery. A grey hat hacker may sometimes violate laws of typical ethical standards, but does not have the malicious intent typical of a black hat hacker. The term came into use in the late 1990s, derived from the concepts of “white hat” and “black hat” hackers. 

Unethical hacking refers to the use of advanced technology for exploiting weaknesses and breaching defenses in a computer system. In this type of hacking, hackers use their skills to gain access to computer systems and steal certain information for the purpose of blackmailing.

Here we are going to talk about the top 5 most dangerous unethical hackers forever. Let’s go.

5. Jonathan James

Jonathan Joseph James was an American hacker who was the first juvenile to be convicted and jailed for hacking in the United States. The story of Jonathan James, known as ‘cOmrade’, is a tragic one. According to the New York Times, what really earned James attention was his hack into the computers of the United States Department of Defense.

Starting at 15, he hacked into Bell South, the Miami-Dade school system and the Department of Defense. He eventually hacked into NASA’s network and downloaded enough source code to learn how the International Space Station worked. At that time the source code was equivalent to $1.7 Million. NASA had to shut down its network for three entire weeks while they investigated the breach, costing an additional $41,000.
