Nowadays, the worm is one of the major threats of devices that communicate through network. The analysis and modeling of the spread of such kind of malware, conduces to the finding of defense methods, infection containment methods and as a result, user protection. In this Master’s thesis, the topological characteristics of complex networks will be analyzed, through which will appear the amount of influence they have on the spreading procedure of worms in real networks. In addition, there will be a separation of worms based on their characteristics, an analysis and evaluation of epidemic and other already known worm propagation models, as well as, there will be a presentation of worm propagation models in several real networks which will be evaluated. Finally, we will propose an XSS worm propagation model in online social networks which is based on the two-factor worm model and it will be simulated on Matlab.
