head_dunce writes: A cyber attack on Russian tech giant Yandex’s servers in August and September was the largest known distributed denial-of-service (DDoS) attack in the history of the internet, the company said on Thursday. The DDoS attack, in which hackers try to flood a network with unusually high volumes of data traffic in order to paralyse it when it can no longer cope with the scale of data requested, began in August and reached a record level on Sept. 5. “Our experts did manage to repel a record attack of nearly 22 million requests per second (RPS). This is the biggest known attack in the history of the internet,” Yandex said in a statement. The previous record was held by Cloudflare, which said last month that it had mitigated a 17.2 RPS DDoS attack.
