A botnet consists of a collection of compromised computers controlled by a botmaster
, which issues instructions to the infected computers through the command-and-control (C&C) server.
Furthermore, it is a network for sending commands and receiving results managed by a botmaster
 introduced a traffic based IDS (T-IDS) for botnet, which includes number of compromised machines known as bots, remotely controlled by a machine known as botmaster
. The proposed approach makes use of a novel randomized data partitioned learning method (RDPLM) and analyzes packet header rather than packet payload to identify intrusion.
Botnet  comprises many compromised hosts under the control of the botmaster
These controls are orchestrated by the BotMaster
or the command center of the botnet.

for illegal activities in a mobile environment.
(Anything About Caribbean Aboriginals from an Online Networked Assistant), a chatbot designed to answer questions about Caribbean Amerindians and her anthropologist botmaster

, uses one or more central servers to compromise and acquire control of vulnerable computers using malware.
A botnet is a network of thousands of compromised computers (bots) under the control of botmaster
, which usually recruits new vulnerable computers by running all kinds of malicious software, such as Trojan horses, worms, and computer viruses .
Bots are infected machines that are controlled remotely and carry out malicious online tasks, such as sending spam e-mails, for their botmaster
. Bots infected nine out of 201 unique machines we observed in Macha, with about 100 more exhibiting suspicious behavior that might be related to botnets.
