| Abstract: |
| This work presents the development of a botnet that can be controlled through an Internet Relay Chat (IRC) server and is able to perform distributed denial of service attacks (DDoS), besides can execute shell commands remotely. The bots that make up this network were developed in the C programming language initially focused on devices running under the Linux platform. The bots can automatically propagate on the network that they are on or by a specified network trying to replicate themselves on devices with a TELNET protocol port (port 23) open and has a common username and password, different sets of usernames and passwords can be specified in a file. GNU wget software was used to download the bot copy to the new device. By making a copy of the bot's payload, the attacker can use this device to execute shell commands from the infected device and can also perform denial of service attacks in conjunction with other devices belonging to the botnet. The types of DDoS developed are TCP SYN flood and UDP flood. At the end, a network analysis with Wireshark is done though the execution of DDoS attacks. |
