What is a DDoS botnet?
A DDoS botnet refers to a group of computers that have been hijacked and are under the remote control of a malicious actor. These bots are used to carry out distributed denial-of-service attacks against a targeted victim.
How are botnets created?
Botnets are created by infecting devices with malware through phishing emails, drive-by downloads, exploiting software vulnerabilities, or distributing infected software through untrusted channels. Once infected, the device becomes a "zombie" that can receive and execute commands from the botnet operator through a command-and-control (C&C) server.
How large are botnets?
Botnets can range from a few hundred to millions of compromised devices. The size of a botnet directly correlates with the potential damage it can inflict through DDoS attacks.
How are botnets mitigated?
Defending against botnets requires keeping software up to date, using strong unique passwords, implementing network monitoring, and deploying DDoS protection services that can absorb and filter attack traffic.
