How malware spreads?

There a three ways in which malware can spread. These include email, web or directly and are the vector classes that are of particular interests to cyber security experts.

  • Email – this is a very simple and effective method of spreading malware throughout your computer system. Criminals can send you applications secretly that will collect data the moment that they are opened.  This can happen when you get emails sent to you from untrusted sources and most of them have links that directs you to a convincing version of your bank for example.
  • Web – criminals can design websites that can exploit vulnerabilities in your system. A typical example maybe something when a pop up ad warns you that your computer has a virus and it will ask you to click to clean the virus to get rid of it.
  • Direct – this includes using a USB infected device that can exploit the host operating system from within the network or social engineering tactics. It sounds simple but it too is very effective.
