Terrorism is the use of force or brutal violent force against people or property in order to intimidate the population and achieve various goals. At the end of the 20th century, it became one of the most serious threats to public security. In the modern world, the danger of being attacked by radicals or witnessing such an act is common. The cases of terrorism and the transformation of the international situation over the past 20 years make people realize the global nature of the current events. It is evident that phenomenon is highly dangerous for society, that is why nowadays people all over the world are trying to prevent these incidents. However, aside from making people more cautious, it would also be helpful to analyze the objectives and strategies that those organizations implement to accomplish them. As an example of a modern terrorist group, the Islamic State of Iraq and Syria (ISIS) will be presented and investigated as this is one of the most well-known and destructive forces that brought chaos around the world.

The most distinctive feature of ISIS is their innovative approach to fulfilling their ultimate goals by using the means of media influence to recruit supporters in its ranks. Therefore, it can be assumed that this war is fought by not only military means but also by manipulative psychological methods. In recent years the organization has made itself known by distributing videos on the Internet of American hostages who were brutally executed. These events caused fear and hatred around the world, which was the initial goal of ISIS. The primary goal of the executioners is not to kill as many local and western prisoners as possible, but first of all, to make people talk about ISIS. They manage to achieve that by using such a powerful catalyst as social media that work on the principle of viral distribution of information. Such a strategy of intimidation more than once helped radical Islamists to seize cities and villages in Syria and Iraq without firing a shot. In addition, it also explains why for some people, this organization becomes attractive. Such ideological
