How does a DDoS attack work?

In this type of attack, the website is downed by sending thousands of requests to the targeted server using various computers and devices.

By taking advantage of machines or servers spread over different areas, they create a network which is called botnet. Each affected machine attacks the target server as a bot.

In this way, they send millions of requests to the target server in no time, which the site server cannot handle and crashes, then the site stops working.

The world's largest and popular website Amazon, Netflix, PayPal, Visa and Github (popular coding website) have also been affected. The problem of DDoS attacks was very less in 2003 but gradually it increased and in 2018 compared to 2003 increased by 90%, which means that more attacks have started happening now.
