Decompilation of Specialized and Advanced Instruction Sets
Holub, Juraj ; Kolář, Dušan (referee) ; Křivka, Zbyněk (advisor)
V dnešnej dobe je proces analýzy nebezpečného softvéru dôležitou súčasťou informačných technológií. Jedna z kľúčových techník je spätný preklad škodlivých binárnych programov. Spätný preklad je komplexný proces, ktorý rieši niekoľko projektov. Projekt RetDec sa zameriava na flexibilný návrh a riešenie spätného prekladača s možnosťou znovupoužiteľnosti. Cieľom tejto práce je zlepšenie spätného prekladu pokročilých inštrukčných sád pre architektúru x86. Bola navrhnutá nová optimalizácia pre FPU registrový zásobník. Bola rozšírená podpora prekladu inštrukčných sád jednotiek FPU a SSE. Nové rozšírenia boli implementované a otestované z hľadiska efektivity a kvality spätného prekladu.

Design of system model of L23 Blanik sailplane
Šenkýř, Miroslav ; Mališ, Michal (referee) ; Urík, Tomáš (advisor)
The aim of this diploma thesis is to create useful reference models of the glider L-23 Super Blaník and their use for framework proposal technology of production, which will improve accuracy and reduce labor intensity of production. The introduction of the thesis describes history of glider and historical overview of geometry transmission in terms of structure. The next chapter of the thesis deals with the description of reference models and rules of their creation. Section describing coordinate systems is closely linked with the previous chapter. Another section of thesis is dedicated to the importance of reference models in the product lifecycle. The creation and tuning of reference models of glider is described in the next chapter of thesis. The penultimate chapter deals with experiment, which allowed verification of reference model and product. The conclusion of the thesis describes proposed technology of production where used verified reference models and modern tools of CAD systems refine and facilitate production. The main objective in designing of reference models was the definition of high quality and usable surfaces. Also proposal technology of production was processed in order to ensure the improvement and simplification of manufacturing process.

Extraction of Static Features from Binary Applications for Malware Analysis
Pružinec, Jakub ; Hanáček, Petr (referee) ; Kolář, Dušan (advisor)
Podoby škodlivého software sa deň čo deň menia a vyvíjajú. Vzniká tak nutnosť jednostaj tvoriť, aktualizovať a zlepšovať metódy na analýzu škodlivého software. Jedným z možných prístupov ako bojovať proti škodlivému software je klasifikovať ho na základe určitých statických charakteristík. Táto práca sa zaoberá návrhom a extrakciou týchto čŕt z binárnych spustiteľných súborov. Cieľom tejto práce je obohatiť nástroj na extrakciu statických rysov o extrakciu nových rysov a overenie ich účinnosti pri klasifikácii škodlivého software. Nástroj je vyvíjaný v spolupráci so spoločnosťou Avast, kde sa používa v systéme zhlukovej analýze.

Measurement and evaluation of the inserts using an optical scanner
Vanek, Richard ; Šrámek, Jan (referee) ; Marek, Tomáš (advisor)
This bachelor thesis focuses on problematics of scanning damaged press dies by an optical 3D scanner. The bachelor thesis starts with a description of 3D scanning, its use in various branches of industry as well as defects that can occur during scanning. This work provides an overview of the methods of 3D scanning and 3D scanners. Another part of the bachelor thesis deals with the procedure of scanning a damaged press die using the optical scanner STEINBICHLER COMET LED 5M followed by processing the acquired data and creating a 3D CAD model. In the final part, the bachelor thesis focuses on comparing and evaluating the obtained data.

Using "reverse engineering" approach when making replica of Al casting by lost wax technology
Bezděk, Adam ; Cileček, Jarmil (referee) ; Horáček, Milan (advisor)
The aim of this thesis was to produce a prototype casting of aluminum alloy with usage of reverse engineering technology. In a production process surface quality and dimensional accuracy was optimized. 3D scanning, FDM technology, ABSplus surface finishing possibilities and investment casting technology is introduced in theoretical part of this thesis. Practical part of the thesis includes description of original parts, their 3D scanning, usage of RE and RP, production of new castings and evaluation of their dimensional accuracy and surface roughness.

System for Pattern Recognition in Binary Files
Milkovič, Marek ; Kolář, Dušan (referee) ; Matula, Peter (advisor)
Malicious software spreads really fast in the age of the Internet and it harms users and their data. Therefore, it is necessary to improve methods of how we deal with its analysis, so we can protect potential victims. This thesis deals with design and implementation of system for generating patterns out of executable files in cooperation with AVG Technologies. The goal of this work is to create a tool that generates a detection pattern from the set of binary files. This work further proposes new types of analyses for extraction of information out of executable files. Designed and implemented system is used in practice for analysis of new malicious code and it is integrated into the clustering system.

Decompilation of AArch64 Binaries in RetDec Decompiler
Kašťák, Matej ; Křivka, Zbyněk (referee) ; Kolář, Dušan (advisor)
The goal of this thesis is to propose and implement a decompiler for the AArch64 architecture. The thesis firstly introduces the concept of reverse engineering, then analyzes the ARM processor platform and architecture of RetDec decompiler from Avast company. In the next chapters, we describe the design and implementation of a module for RetDec. The~purpose of this module is to decompile machine code into LLVM IR instructions which are further processed by LLVM passes. This leads to decompilation to a higher level language.

A production process of rapid prototyping part “shifter lever head” using modern software and technology
Kristel, Peter ; Slaný, Martin (referee) ; Sedlák, Josef (advisor)
Target of this thesis is focused to production a prototype part shift lever head. Project was created with ergonomic elements for better and comfortable manipulation and use. Model of a prototype was filled by design components, which evoked remarkable expression. Production and editing was realized in parametric CAD system. Source data was used from scanning primary body of shift lever head with use a reverse engineering method, 3D scanning using ATOS system. The function of final prototype was verified by commercial available rapid prototyping method Fused Deposition Modeling.

Decompilation from Selected Object File Formats
Bandzi, Michal ; Láznička, Stanislav (referee) ; Matula, Peter (advisor)
Object files contain machine code that can be executed by processor unit. Structure of an object file is defined by its file format. In order to decompile an object file, it is necessary to process and convert file data to internal representation of decompiler. This thesis discusses design and implementation of new modules for file format processing that will be part of the Retargetable Decompiler project. The goal of this work is to add support for Intel HEX and Mach-O file formats and new implementation of already supported Portable Executable file format. Implementation of modules for file formats Intel HEX and Mach-O was successful and it is possible to use them for reverse compilation. Processing of PE file format is not possible in sufficient quality due to errors in used LLVM library.

Decompilation of x86-64 Binaries in RetDec Decompiler
Kubov, Peter ; Křivka, Zbyněk (referee) ; Kolář, Dušan (advisor)
The goal of this thesis is to implement support for decompilation of x64 binary files in the RetDec decompiler. The thesis analyses different approaches to reverse engineering, mainly from the view of information technology. After a general classification of decompilers, thesis brings to attention one particular decompiler from Avast company-RetDec. The thesis also deals with the description of broadly used architecture x86, and it's descendant architecture x86-64. In result, the thesis provides new and extends existing classes in C++ to provide missing functionality.
