What is a hacker?
Hackers refer to people with superb computer skills, such as programming skills, familiar with network principles, and the use of computer software. The original definition does not mean network intruders.
Hackers are divided into two types, white hat hackers and black hat hackers. It is not a must for hackers to be treacherous ;
White hat hackers are ethical hackers, usually employed by a cyber security company or expert to conduct intrusion activities under legal circumstances, including penetration testing and finding out security vulnerabilities on the network. The purpose of the white hacker is to improve cybersecurity and not for personal gain.
Black hat hackers are cybercriminals who use illegal ways to gain profits, including hacking computers, hacking into companies’ systems, and ultimately achieving the goal of profit. The more common cyber crimes include phone ransomware attacks, phishing, identity theft, and illegal intrusion into computer systems.
Those are some famous examples of black hat hackers:
- Nicolai Popescu, one of the most wanted criminals in global cybercrime. He claimed to have a global fraud network to defraud money by posting false advertisements at auctions
- Kevin Mitnick, Condor, is a hacker who turned from a black hat to a white hat. He had hacked into the super systems of companies such as Nokia and Motorola, and after being released in 2002, he started to run his own cyber security company.
- .Albert Gonzales, Soupnazi, who is known as the king of phishing, specializes in phishing attacks on victims. He stole 170 million bank accounts worldwide and has served his sentence since 2008.
There are also many hackers with different purposes. For example, some of them keep attacking the systems of an enterprise for revenge or looking for vulnerabilities in significant systems to show off their superb technology. However, it may thus help hackers or white hats to understand the loopholes and carry out illegal intrusions or improve system security.
