This month Akamai blocked the largest distributed denial-of-service (DDoS) attack that hit an organization in Europe.

On July 21, 2022, Akamai mitigated the largest DDoS attack that ever hit one of its European customers.

The attack hit an Akamai customer in Eastern Europe that was targeted 75 times in the past 30 days with multiple types of DDoS attacks, including UDP, UDP fragmentation, ICMP flood, RESET flood, SYN flood, TCP anomaly, TCP fragment, PSH ACK flood, FIN push flood, and PUSH flood.

“On Thursday, July 21, 2022, Akamai detected and mitigated the largest DDoS attack ever launched against a European customer on the Prolexic platform, with globally distributed attack traffic peaking at 853.7 Gbps and 659.6 Mpps over 14 hours.” reads the post published by Akamai. “The attack, which targeted a swath of customer IP addresses, formed the largest global horizontal attack ever mitigated on the Prolexic platform.”

The malicious traffic peaked at 853.7 Gbps and 659.6 Mpps over 14 hours, this is the largest global horizontal attack ever mitigated on the Akami Prolexic platform.

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).
