Q3 2016 DDoS Trends Report: UDP Flood Attacks Make Up 49 Percent of Attacks

Verisign just released its Q3 2016 DDoS Trends Report, which provides a unique view into online distributed denial of service (DDoS) attack trends from mitigations enacted on behalf of Verisign DDoS Protection Services and research conducted by Verisign iDefense Security Intelligence Services.

User Datagram Protocol (UDP) flood attacks continue to dominate in Q3 2016, making up 49 percent of the total attacks in the quarter. The most common UDP floods mitigated were Domain Name System (DNS) reflection attacks, followed by Network Time Protocol (NTP) reflection attacks.

The highest intensity flood attack in Q3 2016 was a TCP SYN flood that peaked at approximately 60 Gigabits per second (Gbps) and 150 Million packets per second (Mpps). This flood attack is one of the highest packets per second attacks ever observed by Verisign, surpassing the previous flood of 125 Mpps mitigated by Verisign in Q4 2015.

The largest attack in Q3 2016 utilized the Generic Routing Encapsulation (GRE) protocol (IP protocol 47) and peaked at 250+ Gbps and 50+ Mpps. This is the first time Verisign observed this type of attack against our customer base.

A Great Collaborative Effort: Increasing the Strength of the Zone Signing Key for the Root Zone

A few weeks ago, on Oct. 1, 2016, Verisign successfully doubled the size of the cryptographic key that generates Domain Name System Security Extensions (DNSSEC) signatures for the internet’s root zone. With this change, root zone Domain Name System (DNS) responses can be fully validated using 2048-bit RSA keys. This project involved work by numerous people within Verisign, as well as collaborations with the Internet Corporation for Assigned Names and Numbers (ICANN), Internet Assigned Numbers Authority (IANA) and National Telecommunications and Information Administration (NTIA).

As I mentioned in my previous blog post, the root zone originally used a 1024-bit RSA key for zone signing. In recent years the internet community transitioned away from keys of this size for SSL and there has been pressure to also move away from 1024-bit RSA keys for DNSSEC. Internally, we began discussing the root Zone Signing Key (ZSK) length increase in 2014. However, another important root zone change was looming on the horizon: changing the Key Signing Key (KSK).

Why .Com is the Venture Capital Community’s Power Player

Article from Cara Hayes, Verisign director of digital marketing, previously published in WIRED.

The Venture Capital (VC) community is well aware of the value of a great domain name. In a recent essay, Paul Graham, venture capitalist and co-founder of the Y Combinator seed capital firm said, “The problem with not having the .com of your name is that it signals weakness.” It’s no wonder that 100 percent of the top 20 Y Combinator companies by valuation have the .com of their name.

Recent data shows that .com is the most popular domain extension for funded startups. That’s because its global recognition and unmatched security, stability and reliability lends instant credibility to brands associated with a .com domain name.

Defending Against Layer 7 DDoS Attacks

Layer 7 attacks are some of the most difficult attacks to mitigate because they mimic normal user behavior and are harder to identify. The application layer (per the Open Systems Interconnection model) consists of protocols that focus on process-to-process communication across an IP network and is the only layer that directly interacts with the end user. A sophisticated Layer 7 attack may target specific areas of a website, making it even more difficult to separate from normal traffic. For example, a Layer 7 DDoS attack might target a website element (e.g., company logo or page graphic) to consume resources every time it is downloaded with the intent to exhaust the server. Additionally, some attackers may use Layer 7 DDoS attacks as diversionary tactics to steal information.

Increasing the Strength of the Zone Signing Key for the Root Zone, Part II

A few months ago I published a blog post about Verisign’s plans to increase the strength of the Zone Signing Key (ZSK) for the root zone. I’m pleased to provide this update that we have started the process to pre-publish a 2048-bit ZSK in the root zone for the first time on Sept. 20. Following that, we will publish root zones with the larger key on Oct. 1, 2016.

To help understand how we arrived at this point, let’s take a look back.
