A Distributed Denial of Service Attack (DDoS) attack happens when a hacker sends so many requests to machines that the entire network goes down.
In the past several years, the number of DDoS attacks have spiked, increasing in both breadth and duration. A massive DDoS attack in 2016 took down Dyn, a major internet provider for companies that included AirBnB, Netflix, PayPal, Visa, Amazon, The New York Times, Reddit, and GitHub. All of them went offline for a day.
While daylong or multi-day attacks aren’t as common as their shorter cousins, which tend to last a few hours, they are on the rise.
To date, half of the world’s DDoS attacks have originated in China. Hackers are beginning to use more sophisticated tools, which means that future attacks will be larger in scope and could achieve greater impact.
