Dostál, Otto ; Vlček,, Martin (referee) ; Šárek, Milan (referee) ; Hajný, Jan (advisor)
The thesis deals with the topic of computer crime. Foremost, it demonstrates on an example of the operation of a medical image information processing system some selected aspects of this issue. It shows that it is always necessary to monitor the current state of the technical knowledge at the time, but also the need of addressing the issue within the corresponding legal limits. The thesis presents criminal law reality as a complex system. The links between different parts of the system are examined, and possible shortcomings are considered. The legal instruments and legal limits of the procedures that can be used against cybercrime are evaluated. The thesis focuses especially on the issue of obtaining evidence under the Czech Criminal Procedure Code. It presents a proposal on how to understand individual procedural legal institutes and for what purposes and how to use them. Consequently it suggests legal procedures for specific selected practical situations.

Hacktivism: Politics, Crime, or Fun?
Raška, Jindřich ; Froehling, Kenneth (referee) ; Kotásek, Miroslav (advisor)
Cílem této bakalářské práce je zanalyzovat fenomén zvaný hacktivismus, jeho význam, dopady na společnost a motivaci jeho aktérů. Termín hacktivismus se skládá ze dvou následujících termínů; aktivismus, který bývá ve většině případů politicky motivovaný a hacking, jenž se jedná o kriminální činnost za účelem zneužití chyby nebo nedokonalosti výpočetního systému. Za účelem efektivního dosažení svého cíle, se aktéři hacktivismu, stejně jako jiní aktivisté, většinou organizují do skupin. Práce je též zaměřena na motivaci a následky konání těchto organizovaných skupin, zejména na skupinu s názvem Anonymous, s exemplárními příklady jejich akcí z minulosti.

Criminological and criminal law aspects of the ransomware spread
Lédl, Kryštof ; Gřivna, Tomáš (advisor) ; Richter, Martin (referee)
67 Criminal-law aspects and criminological aspects of ransomware spread Abstract The thesis deals with the ransomware spread and its exploration from the perspective of criminology and substantive criminal law. This theme is still relevant as ransomware is still a highly used form of cybercrime, whose method of execution is being constantly improved by the perpetrators. The theme is further relevant because this form of cybercrime is also used as a form of waging war against another state, as may be seen e.g. in the increasing number of cyber-attacks incurring in connection with the current war between Ukraine and Russia. The first part of this thesis defines the term ransomware and then briefly describes the history of this type of cybercrime. This part further describes the different types of ransomware currently recognized by the professional community. Current trends in the ransomware spread are also outlined. The second part discusses the criminological aspects of ransomware, focusing primarily on explaining the ransomware spread by the criminological theories, examining the personality of the perpetrator and the victim from a criminological perspective, and exploring other criminological aspects of ransomware. The third part of the thesis concerns the assessment of ransomware spread under substantive...

Criminological aspects of cybercrime
Gemeri, Peter ; Gřivna, Tomáš (advisor) ; Bohuslav, Lukáš (referee)
Criminological aspects of cybercrime Abstract (EN) This thesis is a study of specific aspects of cybercrime in regards to banking and non- banking financial institutions in Czech republic. By comparing results of third-party analytical resources and own findings obtained by strategically performed interviews with personnel in leading positions in cyber-security careers, the thesis describes causes and results of cyber-attacks and related preventive measures with emphasis on their respective place and priority in the cybersecurity policy of the organization. The main finding is that the biggest risk to the organization seems to be its own employees. That is why the entity cannot simply trust in the security of its perimeter by protecting only its border, but has to also consider its internal part. An equally important finding is the fact that mechanisms for the prevention of cybercrime take a large number of non-mutually exclusive forms, and in order to maintain the highest possible level of security, it is appropriate to layer these measures into complex units. Keywords Cybercrime, cybersecurity, criminology, financial organizations, cybercrime prevention

Furthermore, this chapter is dedicated to the division of crime into latent and registered crime and the sources of information about registered crime. In particular, it focuses on official crime statistics. In the second chapter, the issue of latent crime is discussed in more detail. It defines the concept of latency, in which cases it is considered being latent criminality and what its types are. Furthermore, the ratio of latent and registered crime, the rate and extent of latency are described. At the end the possible causes of its existence are presented, one of the main reasons being the failure to report the crime by its victims. The third chapter focuses on possible methods of detecting latent crime, where more space is subsequently devoted to the two most important methods, namely victimization surveys and self- report studies. For both of these...
