The Nexusguard Q3 2018 Threat Report has revealed the emergence of an extremely stealthy DDoS attack pattern targeting communications service providers (CSPs).
Comparison between normal attack traffic and attack traffic with legitimate traffic
This new vector exploits the large attack surface of ASN-level (autonomous system number) CSPs by spreading tiny attack traffic across hundreds of IP addresses to evade detection. The ongoing evolution of DDoS methods suggests that CSPs need to enhance their network security posture and find more effective ways to protect their critical infrastructure and tenants.
