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.

Phishing Detection in Web Pages
Beňo, Marek ; Hrivňák, Ján (referee) ; Holkovič, Martin (advisor)
This work deals with the design of a phishing attack detection and classification tool. The work describes techniques and forms of phishing attacks and availible tools and techniques for phishing detection. Based on the analysis of existing tools a solution for file classification is proposed. Implemented tool handles input parsing and creation of input model. Model is based on hybrid analysis of input file and URL. Using the YARA tool, YARA rules are applied which are then used in creation of input classification. Analysis of input model and definition of classification rules is enabled by implemented YARA module. Implemented solution makes it possible to define YARA rules for phishing classification based on the structural properties of a phishing file and features of source URL.
