DDoS Threat Report 2018 Q3

The quarterly report, which measures thousands of DDoS attacks around the world, showed Communications Service Providers (CSPs) were targeted by 65.5 percent of DDoS attacks in Q3, given their extensive networks enabling access to tenants’ assets. Attackers were found to have contaminated a diverse pool of IP addresses across hundreds of IP prefixes (at least 527 Class C networks, according to Nexusguard findings) with very small-sized junk traffic. As a result, the year over year average attack size in the quarter fell measurably - 82 percent.

  • New form of attack are aiming CSP networks.
  • A stealthy, new volumetric attack contaminate legitimate traffic across hundred of IP prefix with small-sized, junk to bypass detection.
  • SSDP Flood attack increase 639%.
  • Average attack size per IP fall to 0.972 Gbps during Q3.

Attack vectors discovered via Nexusguard’s honeypot network show that amplification attacks were dominant in the quarter. Simple Service Discovery Protocol (SSDP) Amplification attacks were the most frequent, accounting for 94.1%. CHARGEN came in a distant second at 2.4%, while DNS Amplification followed with a scant 1.8% of attacks observed in Q3.
