I recently sat down with Steve Saunders of Light Reading to talk about the role DNS plays in understanding and fighting emerging cyberthreats. In the interview, we went through the highlights of Nominum’s recent Data Science report, in which our Data Science team studied more than 15 trillion queries over a three-month period and reported on the world of cybersecurity through the lens of DNS, uncovering trends in phishing attacks, DDoS, the Mirai botnet, Locky ransomware, IoT-based threats and more.

With cyberthreats increasing in size and scope, businesses are scrambling to find new ways to protect their financial and human capital assets. Many enterprise solutions offer endpoint protection and network security, but the SMB sector doesn’t have the budget to deploy enterprise security solutions and typically lacks the in-house expertise to keep their networks and users adequately protected. In particular, as employees bring mobile devices onto corporate networks, and with new attack variants being introduced almost daily, small and mid-sized businesses have no way of keeping up. This is where communications service providers (CSPs) can step in to provide a broad layer of protection, visibility, and control from within their own networks.
One of the biggest cyberthreats making the rounds on the internet is the Mirai botnet. Mirai targets connected Internet of Things (IoT) devices, using each infected device to launch DDoS attacks and cause website outages around the globe by flooding them with queries. Examples of recent Mirai-generated web outages are the Dyn attack which took down or significantly slowed sites like Airbnb, Twitter, the New York Times, CNN, Fox News, Netflix and many other popular domains in late October of this year, as well as the attack that temporarily took down security expert Brian Krebs’ KrebsOnSecurity website in September.
Nominum’s inaugural security report published by its Data Science team, Data Revelations: Fall 2016, includes an analysis of some of the largest threats that are impacting organizations and individuals, including ransomware, DDoS, mobile malware, IoT-based attacks and more. Since DNS is the launch point for over 90% of cyberattacks, it offers a great vantage point from which to examine, understand, thwart and proactively prevent threats1. With industry-leading research experience, and by applying machine learning, artificial intelligence, natural language processing, neural networks and more, Nominum Data Science is able to locate, analyze, prevent and predict some of the most sophisticated and dangerous cyberthreats ever to hit the internet.
Nominum Data Science just released a new Data Science and Security report that investigates the largest threats affecting organizations and individuals, including ransomware, DDoS, mobile device malware, IoT-based attacks and more. Below is an excerpt.
On Friday, October 21, 2016, there was a major distributed denial of service (DDoS) attack that took down major U.S. company websites, including Twitter, Paypal, The New York Times, Box, Netflix and more. The attack targeted managed DNS provider Dyn Inc., which hosts the authoritative DNS for these popular domains. The attack originated from a large number of compromised IoT devices, including internet-connected cameras, routers and digital video recorders.
Data scientists put in a tireless amount of work tracking cybercriminals—from specific individuals to entire organizations—looking at their behavior and the methods through which they attempt to compromise data. Because DNS is a ubiquitous protocol that’s used for most internet interactions, it also provides fertile ground for cybercriminals to launch malware. Nominum Data Science examines massive volumes of DNS data—100 billion queries daily—to detect anomalies and uncover the patterns of malicious code authors before other security experts.
This story has been told thousands of times before – a botnet is born, a botnet goes down, a botnet tries to get its bots back together. But the story of Necurs is unique.
