Conversion of Grain Silo in Zlin
Blažek, Jan ; Štikar, Jaroslav (referee) ; Nový, Alois (advisor) ; Donaťáková, Dagmar (advisor)
The Bachelor’s Thesis is based on the architectural study which was done in the summer semester of the third year of my bachelor’s studies. The goal was to create an alternative way how to use this building. The new owner wants to use it mainly for storage and other, mainly auxiliary services. That is why concrete silos were torn down and the object should be turned into a standard multi-stage structure. The main idea of this work is to suggest alternatives what may remain a private initiative. Not only that would therefore not demand additional public expenditure, it could also attract a wide audience with its attractive content. The proposal outlines a friendly variant to the public resources and also has a positive economic benefit within the city of Zlin. That includes adding attractive features into the original grain silos‘ spaces – indoor skydiving, indoor diving, climbing wall etc. This would create an adrenaline centre accompanied with supporting features - commercial areas, a restaurant with a terrace and accommodation. Visual access to internal activities while maintaining the character of the Bata architecture from the main visual axis by this extraordinary object would not only be more attractive, it could also ensure its long-term future.

Analysis and Detection of PWS Malware
Blažek, Jan ; Křoustek, Jakub ; Dzurenda, Petr
Cyberdefense became important, especially duringthe last decade. The rapid growth of information technologiescaused a significant increase in cyber attacks and threats onthe Internet. Malware analysis forms a critical component ofcyberdefense mechanisms. In this article, we study the issue ofmalicious code and its various types, with a specific focus on thetype known as PassWord Stealers (PWS). To do so, we deployedseveral methods of analyzing binary executable code, such asstatic and dynamic analysis, and sandboxing. We analyze 11recently discovered malware families. From that, we discovered3 new strains of malware, namely SevenStealer, NeedleDropper,and AtlantidaStealer. Furthermore, we have created appropriatedetection rules for all of these malware, which have improvedthe detection capabilities of Avast anti-virus (AV) softwareworldwide. At the end of this article, we present the resultingdata illustrating the spread of analyzed malware in the user baseof the Avast company.

Analysis and detection of PWS malware
Blažek, Jan ; Ricci, Sara (referee) ; Dzurenda, Petr (advisor)
Cílem této bakalářské práce je studium problematiky škodlivého kódu a jeho jednotilivých typů se specifickým zaměřením na typ PWS (z angl. Password Stealers). Práce představuje různé metody analýzy binárního spustitelného kódu jako jsou statická a dynamická analýza, nebo sandboxing. Použitím těchto metod bylo analyzováno jedenáct rodin malwaru. Tři z nich jsou novými objevy. Práce taktéž pojednává o tvorbě detekčních a klasifikačních pravidel a jejich následné implementace v jazyku YARA. V textu je vytvořeno několik detekčních pravidel klasifikující specifické rodiny typu PWS. V práci jsou uvedeny výsledná data znázorňující šíření popsaného malwaru v uživatelské bázy společnosti Avast. Na konci práce je vypracováno laboratrní cvičení zaměřené na reverzní inženýrství a analýzu malwaru.
