Platform for Cryptocurrency Address Collection
Bambuch, Vladislav ; Pluskal, Jan (referee) ; Veselý, Vladimír (advisor)
Cílem této práce je vytvořit platformu pro sběr a zobrazování metadat o kryptoměnových adresách z veřejného i temného webu. K dosažení tohoto cíle jsem použil technologie zpracování webu napsané v PHP. Komplikace doprovázející automatické zpracování webových stránek byly vyřešeny techonologí Apache Kafka a jejími schopnosti škálování procesů. Modularita platformy byla dosažena pomocí architektury microservices a Docker containerization. Práce umožňuje jedinečný způsob, jak hledat potenciální kriminální aktivity, které se odehrály mimo rámec blockchain, pomocí webové aplikace pro správu platformy a vyhledávání v extrahovaných datech. Vytvořená platforma zjednodušuje přidávání nových, na sobě nezávislých modulů, kde Apache Kafka zprostředkovává komunikaci mezi nimi. Výsledek této práce může být použit pro detekci a prevenci kybernetické kriminality. Uživatelé tohoto systému mohou být orgány činné v trestním řízení nebo ostatní činitelé a uživatelé, zajímající se o reputaci a kreditibilitu kryptoměnových adres.

Tool to support DoS testing
Kamenář, Filip ; Gerlich, Tomáš (referee) ; Martinásek, Zdeněk (advisor)
The master thesis deals with denial of service attacks and their implementation in own application, called ptdos, that allows testing of web applications using the implemented attacks. Ptdos is also capable of monitoring the progress of testing as well as its evaluation. In the theoretical part of the thesis, the basic concepts are defined, the classification of attacks into categories is described and the individual attacks are discussed in detail in order to explain how the denial of service should occur in the context of an attack. The practical part of the thesis describes the design of the ptdos application architecture and its subsequent development, including a description of the implementation of all the selected attacks. The last part of the thesis is the testing of the application, which includes the creation of a test network and the analysis of all implemented attacks using different scenarios.
