The development of technology in today’s world has brought many advantages and disadvantages. While the digitalized world enables us to perform our transactions more easily, it also created the need to ensure the security of these transactions. The world of our age is the world of technology and the common point of all technologies is cyber security.

Malware, a type of cyber attack, is a type of malware that infects computers, can process and steal data without the device owner’s permission. There are many types of malware. Some of those;

  • Ransomware 
  • Trojan 
  • Worms 
  • Bot 
  • Rootkit 
  • Spyware 
  • Virus 
  • Adware 
  • Scareware 
  • Logic Boms 
  • Trap Door 
  • MITMO 

Ransomware: It is one of the most popular types of cyber attacks of recent times. Computers are intercepted using information obtained through a variety of social engineering and phishing methods. Attackers then capture and encrypt data on computers. After that, they demand a ransom. Even if the victim has paid the ransom, there is no guarantee that they will completely survive this attack. The most popular method of integrating this malware into computers is emails sent to the target via fake email accounts. By sending an email, such as a government agency or a bank, the target is trapped. Therefore, it is one of the simplest security measures not to open e-mails that you are not sure about.

Trojan: This malware, called a Trojan horse, hides itself until the right moment of the attack after it enters the systems. The Trojan may present itself as an application. For this reason, games, software, etc. that you will download to your phone or computer. Before downloading apps, make sure they are safe. 

Worms: These malicious software, which enters computers through security holes or vulnerabilities, reproduce by itself without the need for any action. The aim is to take over the systems by spreading rapidly on the network.

Bot: Malware that runs as a computer program and can be controlled by multiple external sources. This malware; chat etc. It aims to capture various information through web-based programs. Other malware may also be needed to carry out this attack. 

Rootkit: It is a type of malware designed to remotely access and control a computer.The aim here is to infiltrate the computer without being caught by users and security software, if any. As a resultif a rootkit attack succeeds; data can be stolenall operations can be performed on the computerfiles can be rundifferent malware can be installed. Rootkit attacks can be carried out by exploiting a vulnerability. 

Spyware: This malware can infiltrate computers through a Trojan horse or a program downloaded to the computer. The goal is to collect data and track browser history. Therefore, it is a dangerous type of malware. With this malware, the security settings of your computer can be changed and accordingly different malware attacks can be opened. 

So how can a malware attack be detected? A few tips for this;

  • If your computers are running slow,
  • If your computers have firewall and security software, when disabled,
  • When you receive unfamiliar error messages.
