In early September, Russian tech giant Yandex repelled the largest DDoS attack in the history of Russian. The American cybersecurity company Cloudflare, which specializes in such attacks and cooperates with Yandex, confirmed the scale of the cyberattack.

Yandex stated that its experts managed to repel a record attack of nearly 22 million requests per second (RPS). “We are conducting an investigation together with the contractors. This is a threat to infrastructure on a national scale," the representatives of the company said. Yandex also clarified that the DDoS attack was difficult to contain, but it did not affect the operation of services and user data.

In August Cloudflare reported that its autonomous edge DDoS protection systems automatically detected and mitigated a 17.2 million request-per-second (rps) DDoS attack, an attack almost three times larger than any previous one known to the company.

UPD (September 9): Qrator Labs published a report on the presumed attacker, an IoT botnet Meris. Unlike its well-known predecessors, Meris relies on transmitting a high number of requests per second. Most of the devices exploited to form the botnet were networking gear from the Latvian vendor MikroTik.
