Bots are harmful processes controlled by a Command and Control (C&C) infrastructure. A group of bots is known as botnet to launch different network attacks. One of the most prominent network attacks is Distributed Denial of Service (DDoS) attack. Bots are the main source for performing the harmful DDoS attacks. In this paper, we introduce a D-SCAP (DDoS Scapy framework based) bot to generate high volumes of DDoS attack traffic. The D-SCAP bot generates and sends continuous network packets to the victim machine based on the commands received from the C&C server. The DDoS attack traffic can be generated for cloud environment. The D-SCAP bot and the C&C server are developed using Python language and Scapy framework. The D-SCAP bot is compared with the existing well-known DDoS bots. © 2019, Springer Nature Singapore Pte Ltd.
