The Covid-19 outbreak and the subsequent lockdown dramatically changed the behaviour of billions of people across the world who switched to the digital space. In a matter of weeks, the restricted movement of people shifted work, connecting and entertainment to online. With the rise of social distancing, we have been directed to our devises for almost any activity, which has consequently increased our vulnerability from all forms of cyberattacks. If we consider the fact that we are living in times of progressive informatization of society it is realistic to expect the new scenarios for disruption of individual, corporate, national and global security. Cyberspace does not recognize geographical and political boundaries, therefore cyberthreats do not recognize borders between countries. The fact is that cyberspace is accepted as a legitimate battlefield (the socalled fifth battle space together with: land, air, sea and outer space) in strategic documents of most countries of the world. This, of course, further complicates relations in the international arena, setting new challenges for experts in international war law and humanitarian law, and actualizes the issues of international legislative harmonization. It is not necessary to emphasize the necessity for cooperation between international institutions responsible for cybercrimes, as well as the exchange of information between States, their regulatory bodies and security services to counter cyberthreats.
