The cyber epidemiological analysis of computer worms has emerged a key area of research in the field of cyber security. In order to understand the epidemiology of computer worms; a network daemon is required to empirically observe their infection and propagation behavior. The same facility can also be employed in testing candidate worm countermeasures. In this paper, we present the architecture and design of Pseudo-Worm Daemon; termed (PWD), which is designed to perform true random scanning and hit-list worm like functionality. The PWD is implemented as a proof-of-concept in C programming language. The PWD is platform independent and can be deployed on any host in an enterprise network. The novelty of this worm daemon includes; its UDP based propagation, a user-configurable random scanning pool, ability to contain a user defined hit-list, authentication before infecting susceptible hosts and efficient logging of time of infection. Furthermore, this paper presents experimentation and analysis of a Pseudo-Witty worm by employing the PWD with real Witty worm outbreak attributes. The results obtained by Pseudo-Witty worm outbreak are quite comparable to real Witty worm outbreak; which are further quantified by using the Susceptible Infected (SI) model.
