A type of sophisticated invalid traffic (SIVT), a bot network (or botnet) is a network of computer devices that have been hijacked for fraudulent purposes. Cybercriminals introduce malware to a networked device, via email or other internet use, and then infect other linked devices to take control of the entire network. They then either defraud the network owner – for example, via their access to confidential information or financial details – or use the ‘zombie’ network to carry out further scams.
