DEVS-Based Modeling and Simulation to Reveal Emergent Behaviors of IoT Devices
Published in Larry B. Rainey, O. Thomas Holland, Emergent Behavior in System of Systems Engineering, 2022
Botnets are networks of infected devices that are used by attackers to perform network malicious activities [2]. Previous studies have shown that the traffic pattern that is generated by botnets can be detected using flow and packet attributes [14–18]. IoT botnets, such as Mirai, Torii, Hajime, BASHLITE, QBot, and their variants, target IoT devices as they are weakly configured and can be infiltrated easily using manufacturer’s default usernames and passwords. Also, IoT devices are always connected to the Internet, which make them attractive and reliable surface for hackers to launch network attacks. IoT botnets can infect millions of devices that are then used to launch a massive DDoS attacks such as the unprecedented attack on Dyn, OVH, and KrebsonSecurity which cocurred in 2016 by Mirai IoT botnet.

For clear knowledge of how a botnet runs, its basic elements should be understood first. However, there are botnets which follow different structures in order to avoid detection [1,7], as shown in Figure 6.1. A bot is installed malware in an unguarded host which is responsible for performing series of malicious tasks. Installation of this malware can be done through numerous processes, like contaminated websites. These are particularly implemented in such a way that whenever the victim starts their internet-connected machines, only then does the bot initiates its processing. Using a secure command-and-control (C&C) channel, the botmaster sends commands. The main point to note is that bots are not systems or applications weaknesses, but are malware that are spread by contaminated websites, and so on. A botnet is a network of compromised machines called bots and an owner who controls the bot through the command-and-control server to execute malicious activities. Botmasters publish commands to the bots to execute unlawful tasks.

Botnets are assembled by infecting mobile devices, namely, bots, in order to be able to execute code on them that will allow the botmasters to remotely control them. To this end, utilization is made of the services of a command and control (C&C) server, which is a server that is controlled by the botmaster. According to the type of attack that will be performed by the botnet, the C&C server issues the appropriate commands to the infected bots. These entities coupled with the appropriate communication channels collectively form the notion of a mobile botnet. There exists a plethora of features that can be utilized to build a taxonomy of botnets ranging from the infection vector to the detection and take-down of the botnet, which we review in this chapter, also describing in detail the various possible architectures and typical examples of mobile botnets attacks.

Botnet is a term that refers to a group of compromised computers (also called as zombies) that are controlled by a single individual/group for usually nefarious purposes using Command and Control architecture [1]. Nowadays, botnets are usually available as a service to attack various targets for pay. Further machines are ‘recruited’ by infecting them with malware by exploiting vulnerabilities within the machine.
A survey of phishing attack techniques, defence mechanisms and open research challenges
Published in Enterprise Information Systems, 2022
A botnet is a string of linked computers that are organised to perform a task together. They are computers linked to perform a variety of repetitive tasks to keep websites running. It is most widely used in Internet Relay Chat (IRC) connections. These types of botnets are legal and even useful for the maintenance of a smooth Internet user experience.
