The type of cyber attack used by Killnet, known as a “distributed denial of service” (DDoS) attack, is a common threat growing in sophistication and frequency. Killnet has been targeting NATO countries since Russia invaded Ukraine and claimed responsibility for recent cyberattacks on local government websites.
What is a DDoS attack and how does it work?
DDoS attacks are malicious attempts to overload a web server and shut down access to a server, service, or network by overwhelming it with a flood of Internet traffic.
Often, DDoS attacks accomplish this disruption by sending malicious traffic from a botnet — a collection of computers or other devices that have been infected with malware and can thus be controlled remotely by an individual attacker.
