FOR205 - Windows Internals for Forensics

All modern malware works within the operating system, not only by exploiting weaknesses but also by using features that are there for everyday use. It is therefore impossible to understand how malware works without a deep understanding of the operating system it targets. This seminar provides detailed information on how Windows works internally, with special focus on common malware attack methods. It includes coverage of Windows’ most recent security features, most of them specifically added to combat malware.
