Google hit by biggest DDoS attack in its history

Ana sayfa / Technology

Denial of service attacks (DDoS) continue to affect major companies. Google announced in a blog post that it faced the largest DDoS attack on record. The attack is seven times larger than the previous DDoS record holder. Here are the details…

The attack broke the record with 398 million requests per second (rps)

In June last year, hackers attacked a Google Cloud customer by sending 46 million requests per second. Lasting 69 minutes, it was the largest attack in Google’s history. However, Google announced today that they blocked a DDoS attempt that was 7.5 times larger.

Google said it stopped the largest DDoS attack ever, which was caused by a newly discovered vulnerability. The attack was carried out with 398 million requests per second (rps). Google used the following statements in its post;

Over the last few years, Google’s DDoS Response Team has observed a trend of distributed denial of service (DDoS) attacks increasing exponentially in size. Last year we blocked the largest DDoS attack ever recorded at that time. This August, we stopped a DDoS attack 7 and a half times larger, using new techniques to disrupt websites and internet services.

This new series of DDoS attacks peaked at 398 million requests per second (rps) and relied on a new HTTP/2 “Fast Reset” technique based on stream multiplexing that affected multiple Internet infrastructure companies. In contrast, last year’s largest recorded DDoS attack peaked at 46 million rps.
