Cybersecurity attacks have become a weekly occurrence in many news columns. One recent example was that of one of our customers, QIWI payment system, successfully mitigating a 480 Gbps memcached amplified UDP DDoS attack.
While we at Qrator Labs would rather stay out of the news, such instances justify all the preparation that we put into mitigating for such attacks. To help others learn from our experience, I thought I’d recap several facts about amplification attacks, so that you too will be prepared ‘when’ the day comes.
