Top 3 biggest DDoS attacks in history
DDoS attacks have already become a significant barrier for doing business affecting companies operating in different fields. The damage they cause may be both financial and reputational. Not only SMEs but also technological giants may be vulnerable to DDoS attacks. Let us look closer at the biggest DDoS attacks on well-known brands.
The DDoS attack of 2.5 Tbps struck Google in September 2017. It was a nation-state campaign lasting for 6 months originating from China and, at the time the attack was committed, it was the biggest ever recorded DDoS attack. Malicious actors were trying to slip past automated defences by targeting thousands of the company’s IPs. However, hackers did not achieve their targets. The Google Threat Analysis Group expert Shane Huntley reported that the attack in question was the UDP-amplification state-sponsored attack. Google notified its providers of the exploitation by malicious actors of 180,000 CLDAP, DNS, and SMTP servers.
