Cybersecurity attacks and threats, which are common problems of today; can put individuals, companies, and states in a difficult position. Cybersecurity attack is the name given to all of the attack actions made using various methods to steal, change or destroy data from one or more computers to the opposite computers or networks. These cyberattacks, however serious they may seem, can certainly be prevented. States have protection methods for cyber attacks.
Common Types of Hackers in Cybersecurity Attacks
- White Hat Hackers
White hat hackers are well-meaning hackers who do not break security systems to cause harm. White hats can work with the company that produces the software to find a system’s weak spots. Before publicizing the vulnerability they detect in any system, white hats notify the company/person who developed the software, allow a reasonable time to close the gap, and do not harm the system during this period. It then announces the details of this vulnerability in various newsgroups and websites to inform the public. We can say that the white hats are working defensively. These people are also called “ethical hackers”.
- Black Hat Hackers
Black hat hackers are the opposite of white hat hackers. They engage in harmful activities such as information theft, fraud, terrorism, and deliberate destruction by bypassing security systems without permission. They can do this by remotely accessing a computer or cracking software. Black hats who crack software are called “crackers”.
- Grey Hat Hackers
They are hackers who are walking around the border of legality. They determine the weak points and vulnerabilities of the systems they are the administrators of or support and guide their security policies.
Common Types of Hacks
Malware is short for malicious software. Worms, viruses, and trojan horses can be given as examples. They are malicious software that infiltrates computer systems without the consent of individuals. They can render computers or networks inoperable, hide, reproduce, or give attackers access and remote control of the system.
In this method, which is called phishing attacks, attackers try to steal people’s site and credit card information by sending e-mails that appear to come from reliable sources. Usually, victims who click on the links they send via e-mail are directed to the cloned sites and share the information they entered with the attackers.
3) DoS and DDoS
These methods, which are called Denial of Services and Distributed Denial of Services in English, are attacks to try to prevent some online services from working correctly. Attackers send too many requests to a website or a database and keep the system busy, which can cause systems to stop working. On the other hand, DDoS happens when attacks are made by more than one computer.
4) Man in The Middle
In this type of cyber attack, attackers hide between the victims and the web service they want to access and direct the victims to the service they want to access over their networks. For example, they spoof a Wi-Fi network and the victims get into the attackers’ Wi-Fi instead of the Wi-Fi network they want to access. From now on, attackers can see every action they take and collect users’ data.
