The reality of a DDoS attack with more than 4 million bad requests
Although this is not the largest application-layer DDoS attack that VNETWORK has ever recorded, it is worth noting that it is a targeted attack, targeting VNETWORK customers.
Specifically, the attack began on Friday, from about 9:15 to 9:30 on November 18, 2022. Although within a few short minutes, the attack level reached more than 4 million requests.
With this DDoS attack, if the infrastructure is not large enough and the security technology is not strong enough, then customer websites will easily suffer downtime and damage.
Information about this DDoS attack is recorded as follows
The number of requests peaks from about 9:15 to 9:30
During this DDoS wave, the hacker made a huge amount of bad requests to one of VNETWORK’s client domains.
The total number of requests has been blocked and filtered by the WAF VNIS system (more than 4 million bad requests)
Therefore, only clean traffic goes to the origin server (more than 65k requests).
100% of malicious requests have been blocked
From the graphs, VNIS has completely blocked bad requests and only allowed clean requests from real users to the origin server.
Multi WAF system is loaded to fight DDoS attacks from many countries
At the time of the attack, the VNIS system records error states 5xx and 4xx
5xx statuses documented in detail
How does VNIS prevent these DDoS attacks?
The VNIS platform combines the power of infrastructure (Multi CDN) and advanced security technology (Multi WAF) to help protect websites, applications, and APIs from high-volume DDoS attacks and DDoS attacks on the Application layer.
Currently, VNETWORK has also just upgraded 12 more WAF servers, estimating that each WAF has the capacity to handle more than 800,000 requests.
VNIS also has a smart Multi CDN load balancing system calledAI Load Balancingand a WAF:Scrubbing Centerload balancing system that helps prevent large and sophisticated DDoS streams from many countries.
Besides, VNIS also works closely with network security monitoring centers (SOC - Security Operation Center) in many countries and territories, helping to detect probing attacks early and proactively prevent them when they are detected. The attack is still in its infancy.
VNETWORK brings advanced security to businesses, helping them feel secure in doing business on the internet environment. Therefore, we also support the implementation of service quality commitments (SLAs) for domestic and foreign customers.
Our security team consists of many cybersecurity experts in countries such as Vietnam, Taiwan, Singapore, and Hong Kong… We continuously monitor the network every day to identify new potential threats.
