The literature on botnet-enabled cyber-attacks and the literature on botnet takedowns have progressed independently from each other. In this research, these two literature streams are brought together. Botnet-enabled cyber-attacks and botnet takedowns are conceptualized as collective actions carried out by individuals, groups, and organizations that are linked by the Internet and club theory is used to examine the inner workings of these collective actions. This research examines five scenarios of botnet-enabled cyber-attacks and five scenarios of botnet takedowns to develop a representation of cyber-attacks and infer capabilities of four club types: Attacker, Defender, Botnet beheader, and Botnet operator. The representation developed identifies the dimensions of the three constructs of club theory: club membership size; size of the facility that club members share; and arrangements to operate, purchase/rent and grow the shared facility. Club capabilities were organized into five types: relationships, attack infrastructure, skills, learning, and others.
