Analýza metód perzistencie škodlivého skriptu Powershell

Abstract

This master’s thesis addresses persistence methods employed by malicious PowerShell scripts on Windows operating systems. It analyzes both historical and modern techniques in order to identify vulnerabilities exploited by cyber attackers. In the practical section, selected methods are implemented and tested in a virtual environment. Experiments verify the effectiveness of these approaches and assess the response of current security measures, including antivirus tools. The study provides a systematic classification of persistence strategies and offers recommendations for improving malware detection and strengthening system resilience.
