Bc. Ondřej, Kovář. Attacks on Cryptocurrency Holders and Proposed Security Measures for Their Prevention. Ostrava 2026, VŠB – Technical University of Ostrava, Faculty of Security Engineering, Master's thesis, Thesis Supervisor: Ing. Marek Miškay, Ph.D. The aim of the master's thesis was to analyse physical attacks on cryptocurrency holders and to propose security measures for their prevention. The theoretical part focuses on the security specifics of cryptocurrencies and their differences from the traditional financial system, the typology of attacks, principles of operational security and the relevant legal framework. The practical part is based on a quantitative trend analysis of approximately three hundred documented physical attacks and a qualitative analysis of thirty selected cases, on the basis of which common patterns and key factors contributing to the success of these attacks were identified. Based on the findings, a multi-layered framework of preventive measures structured according to risk profiles was proposed, the practical output of which is a manual for protecting cryptocurrency holders against physical attacks.
