According to Akamai, threat actors used a highly-sophisticated, global botnet of compromised devices to launch the attack.

In September, the Russian Internet giant Yandex was hit by the largest DDoS attack in the history of Runet, the Russian Internet designed to be independent of the world wide web and ensure the resilience of the country to an internet shutdown. The attack was launched by the Mēris botnet and reached 21.8 million RPS (requests per second).
