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.

The attack, which targeted a swath of customer IP addresses, formed the largest global horizontal attack ever mitigated on the Prolexic platform.

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

In the same time, however, in January, Microsoft revealed that Microsoft Azure cloud computing customer in Asia was a victim of the biggest DDoS attack in recorded history which took place in November 2021.
