Attacks and malware
What is Botnet?
A network of infected devices controlled together by one operator, used for spam, DDoS attacks, credential attacks or spreading more malware.
A botnet is a collection of compromised computers, servers, routers or IoT devices that take instructions from the same operator. Each infected device is a bot.
Botnets provide scale: they can send millions of spam emails, launch DDoS attacks, test stolen passwords or deliver other malware. Taking one down usually means seizing or sinkholing its command and control infrastructure.
