Worm origin identification and propagation path reconstruction are among the essential problems in digital forensics. Until now, several methods have been proposed for this purpose. However, evaluating these methods is a big challenge because there are no suitable datasets containing both normal background traffic and worm traffic to evaluate these methods. In this paper, we investigate different methods of generating such datasets and suggest a technique for this purpose. ReaSE is a tool for the creation of realistic simulation environments. However, it needs some modifications to be suitable for generating the datasets. So we make required modifications to it. Then, we generate several datasets for Slammer, Code Red I, Code Red II and modified versions of these worms in different scenarios using our technique and make them publicly available.
