A botnet is a group of compromised computers— often a large group—under the command and control of a malicious botmaster. Botnets can be used for a wide variety of malicious attacks, including spamming, distributed denial of service, and identity theft. Botnets are generally recognized as a serious threat on the Internet. This paper discusses SocialNetworkingBot, a botnet we have developed that...

This paper presents a threat to cyber resilience in the form of a conceptual model of a malware rebirthing botnet which can be used in a variety of scenarios. It can be used to collect existing malware and rebirth it with new functionality and signatures that will avoid detection by AV software and hinder analysis. The botnet can then use the customized malware to target an organization with an...

In this paper, we analyze a large amount of infection data for three major botnets: Conficker, MegaD, and Srizbi. These botnets represent two distinct types of botnets in terms of the methods they use to recruit new victims. We propose the use of cross-analysis between these different types of botnets as well as between botnets of the same type in order to gain insights into the nature of their...

This paper integrates competitive pricing and network design problems for the short life cycle products. The pricing problem determines selling prices of the products for different life cycle phases in a competitive market, as well as acquisition management of returned products. Besides, the selling and acquisition prices are related to the distance between distribution centers and customers. T...

Remote-controlled malware, organized in so-called botnets, have emerged as one of the most prolific kinds of malicious software. Although numbers vary, in extreme cases such as Conficker, Bredolab and Mariposa, one botnet can span up to several million infected computers. This way, attackers draw substantial revenue by monetizing their bot-infected computers. This thesis encapsulates research o...
