DENVER, Nov. 16, 2021 /PRNewswire/ -- Data from the Lumen
Technologies Q3 DDoS Report, released today, reveals that three
fundamental metrics – quantity, size and complexity of DDoS attacks
– all increased in the third quarter of 2021.
Attacks are evolving to use more complex methods, and to target
atypical services such as voice.
Key Findings from the Report
To compile these findings, the security team at Lumen analyzed
intelligence from Black Lotus Labs – the company's threat research
arm – and attack trends from the Lumen DDoS Mitigation Service
platform, which integrates countermeasures directly into the
company's extensive and deeply peered global network.

DDoS Attack Trends
- Lumen mitigated 35% more attacks in Q3 than in Q2.
- The largest bandwidth attack scrubbed in Q3 was 612 Gbps – a
49% increase over Q2 – and the largest packet rate-based attack
scrubbed was 252 Mpps – a 91% increase.
- The longest DDoS attack period Lumen mitigated for an
individual customer lasted 14 days.
- For the first time, 28% of multi-vector mitigations involved a
complex combination of four different attack types, including DNS
amplification, TCP RST, TCP SYN-ACK amplification and UDP
amplification.
- Like Q2, the top two verticals targeted in the 500 largest
attacks in Q3 were Telecom and Software/Technology; the Retail
vertical, which did not make the top 3 in Q2, was the third most
attacked industry in Q3.
IoT DDoS Botnets
- Although Lumen observed a 26% decrease in unique C2s for Gafgyt
and Mirai – two predominant IoT botnet families it continually
monitors – the company observed more than 217,000 DDoS botnet hosts
globally. This represents a 45% increase over Q2 and the most seen
all year.
- Lumen tracked more than 2,100 C2s globally. The countries with
the most C2s were (in order): China, United
States and, tied for third, Taiwan and the
Netherlands.
Mark Dehus, Lumen director of information security and threat
intelligence, shares what companies can do to protect themselves.
"DDoS attacks are rampant, and the frequency doesn't seem to be
slowing down," Dehus said. "If anything, attacks are evolving to
use more complex methods, and are being aimed at services such as
voice that have not typically been targets in recent years."
"At Lumen, we partner with industry trust groups to track
attacks back to their original sources and proactively block
nefarious traffic whenever possible. We want businesses to join the
fight to protect themselves," Dehus added. "First, have a solid
strategy in place to address all potential security issues. Second,
work with an established DDoS mitigation partner – particularly one
that has an ability to track DDoS botnets and find new sources
before they launch an attack. Also look for a provider that offers
application security services like Web Application Firewall and
Botnet Management. And finally, if you find yourself under attack,
look for a solution like Lumen DDoS Hyper, which enables you to
turn up service in about 15 minutes and be in a position to enable
mitigation."
Attack sizes in the Lumen Q3 DDoS Report convey the largest
attacks scrubbed by Lumen global DDoS scrubbing infrastructure,
rather than the largest attacks observed transiting or being
scrubbed by the Lumen network. To learn more about Lumen's
