What Are the Different Types of Cyber Attacks?

Cyber attacks are growing more and more frequent with advancements in technology and more people working remotely, presenting more opportunities for cyber attackers to strike. If you are required to use devices in your role, you must be aware of the many different types of cyber attacks and how to protect your devices. Here are some of the most common examples of cyber attacks:


Malware is malicious software that is used to execute unauthorized actions on a system. Worms, ransomware, and trojans are some examples of malware that can be used to attack a system, each working in different ways. For example, trojan viruses appear as normal software and adware displays ads on your screen. Preventive measures include:

  • Installing antivirus software
  • Firewalls
  • Making sure you and your colleagues are trained in identifying suspicious links and emails
  • Regularly updating your system and software
  • Strong and safe password management


Ransomware is a form of malware where attackers hold a user’s data or system hostage, usually accompanied by a threat demanding payment in exchange for release. These threats are often fake as most attackers won’t gain access to your data or system before you click on one of their malicious links or attachments. Preventative measures include:

  • Only clicking on links from trusted sources
  • Installing up-to-date security software
  • Don’t pay the ransom as there is no guarantee that you will get your files back
  • Reporting any suspicious emails


Phishing is a very common type of cyber attack that often catches vulnerable people unaware. Attacks pose as a trustworthy contact or business and encourage users to provide sensitive information such as bank details and passwords. Alternatively, they often include malicious links or attachments in emails which an unsuspecting user may click on. Preventative measures include:

  • Only opening links from trusted sources
  • Checking the sender’s email address – you can also look up the company online to cross-reference the contact details
  • Checking for spelling mistakes and odd structuring within the email
  • Regularly updated and secure passwords


In man-in-the-middle attacks, a hacker can access sensitive information when it is being passed between two unprotected systems. These attacks commonly occur in places with free Wi-Fi, as unsuspecting users are more likely to connect to these public connections without realizing the danger involved. Preventative measures include:

  • Only connect to secure and trusted Wi-Fi connections
  • Make sure any websites visited are secure
  • Don’t save or send passwords and other sensitive information via unencrypted applications

Which Industries are Most Likely to be Targeted by Cyber Attackers?

The industry your business resides in can impact how likely and frequently you are to experience cyber attacks. The industries that commonly experience cyber attacks are banks and financial institutions, governments, and health industries which makes sense due to the nature of the information they possess. These cyber attacks could be people trying to gain money or sensitive information for personal gains or to steal business ideas.

However, if your business falls outside of the aforementioned industries, this doesn’t mean you should become complacent with your IT security. Any company is at risk if the proper steps are not taken to protect your business and its IT systems. As more companies are offering the option to work from home or in other remote places, this presents more opportunities for hackers to target individuals with cyber attacks. This is most commonly in the form of public Wi-Fi. We have an in-depth blog available with more information on the topic.
