Google won against hackers. It was the largest DDoS attack in history. 400 million times per second

The mentioned DDoS attack (Distributed Denial-of-Service) consists in bombarding the attacked person with as many queries as possible (e.g. attempts to open a website) at the same time. If this number is large enough, the victim’s infrastructure will be overwhelmed and eventually fail. Causing such a failure is the goal of DDoS attacks.

Google repelled the largest DDoS attack in history. 400 million queries per second

As described in August this year. The largest DDoS attack in history occurred. The American company’s infrastructure was flooded with hundreds of millions of requests per second, which at the peak reached 398 million queries per second. The fight against the hackers lasted only about two minutes, but the scale of the attack was gigantic. For comparison, according to Google, in these two minutes the company had to deal with more queries than Wikipedia had to deal with in the entire month of September 2023.

Moreover, the scale of the attack was several times larger than the record-breaking DDoS attack from June 2022, when 46 million queries were generated per second. The trend is therefore upwards and, according to Google, the reason for this is the use by hackers of a new technique of “fast reset HTTP/2 protocol”, which is based on “multiplexing streams”. Google explains that this technique allows you to generate a huge number of queries, and defending against this type of attack is very difficult.

Fortunately, the attack was repelled this time, and Google customers and users of the Internet giant’s services probably did not even feel that the company was under attack. If the attack was successful, Google services – or at least some of them – could stop working for some time. This could have very unpleasant consequences not only for private users, but also (or perhaps especially) for companies.
