Spyware development and analysis

Bachelor Thesis , 2011 , 82 Pages , Grade: 1,3

Computer Science - Applied

This bachelor thesis gives relevant issues about computers today, especially on the use of multimedia systems such as audio and video chat, along with related laws and regulations by government and some past events concerning computer security. Then some basics about computer security, including network basics, and the development of a prototype are described. The prototype development includes web-cam capturing on a victim’s system and the transmission of its images through a network. This prototype is the most important part of the thesis and will cover the investigation with and without oversight by anti-virus
and firewall software. For this purpose, several popular established firewall and anti virus software vendors are analyzed and tested.
