Non-security of the Czech Army's soldiers on social networks
Kulhánek, Jan ; Ludvík, Jan (advisor) ; Kučera, Tomáš (referee)
The aim of this thesis is to examine the risk of the Czech Army not being properly secure on social networks, the behaviour of its uniformed members and their positive identification of social networking sites. The Russian aggression in the Ukraine and the hacking of Czech medical facilities have once again brought up the importance of cybersecurity and the role that it plays in the modern world, with the human factor being positively identified as the weakest link in security. This case study seeks to define the ideal types of soldier behaviour on social media and to analyse the potential risks that each type poses. To this end, this thesis first presents information necessary to fully understand the vast topic of cybersecurity on social media. Next, it defines several ideal types and their building blocks, in order to categorize the social media accounts of soldiers it later analyses. The author concludes that each defined ideal type has inherently problematic behaviours associated with it and carries with it a level of risk for the Army of the Czech Republic. However, the present user and family member ideal types were found to be the riskiest. Key words OSINT, SOCMINT, NATO, Czech Armed Forces, Cybersecurity, Security, Social media, Ideal type analysis, Social engineering Title The insecurity...

Psychology of Phishing Attacks During Crises: The Case of Covid-19 Pandemic
Kaliňák, Viliam ; Erkomashvili, David (advisor) ; Špelda, Petr (referee)
Events and circumstances that accompany crises such as losses of loved ones, losses of material resources, dislocation, or physical harm, have an overall negative impact on people's mental health. It is this impaired state of man which makes him vulnerable to manipulation of social engineers who wants to take advantage of him in order to enrich themselves. This was also the case of the COVID-19 pandemic, the unprecedented crisis in modern history, during which phishing and fraud campaigns rapidly increased as people have been forced to stay safe at home and spent most of a day online. This work analyzes the psychological strategies of cybercriminals on a sample of more than 200 phishing e-mails in order to understand how the situation was abused and what can be learnt to prevent it in the future. It also provides theoretical and research frameworks for researchers who can apply it also on other types of crises. The results contribute to the fields of psychology, cybercrime as well as crisis management. Keywords COVID-19, phishing, social engineering, psychology, persuasion, crises, pandemic, impersonation, pretexting
