DDoS Attack Brings Down U.S. Airport Websites
On October 10, 2022, a Russian hacking group known as Killnet knocked offline the websites of some of the United States’ largest airports. The Monday morning attack impacted fourteen U.S. airports, including Atlanta’s Hartsfield-Jackson and Los Angeles’s LAX, causing them to be briefly inaccessible.

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.
