FloCon 2016 Recap

Last week, OpenDNS Research Labs attended FloCon 2016 where we presented two talks showcasing our latest work in threat research and development.  First, Jeremiah O’Connor and Thibault Reuille presented “The Security Wolf of Wall Street: Fighting Crime with High-Frequency Classification and Natural Language Processing” The talk was received very nicely, and Thibault and Jeremiah enjoyed getting some great technical questions from the audience, which gave us some more fuel to go back and improve our system.

The Avalanche Project: When High Frequency Trading Meets Traffic Classification

One of the key challenges for OpenDNS (now part of Cisco) is handling a massive amount of DNS queries and simultaneously running classification models on them as fast as possible. Today, we’re going to talk about Avalanche, a real-time data processing framework currently used in our research cluster.

First, we have to run some numbers to evaluate the amplitude of our requirements and make smart architecture design decisions. Second, we will assess some similarities with other technical fields (such as quantitative ...

Phishing, Spiking, and Bad Hosting

At OpenDNS Labs we have developed a number of predictive models to hunt down evil on the Internet. We have discussed in previous blogs and conferences our algorithms NLPRank [1][2][3], Spike detector [4][5][6], and malicious IP space/rogue host detectors [7][8](section 14)[9][10][11][12][13][14][15].

In this blog we will discuss how we integrate all of these detection models to improve detection coverage of current threats and walk through a few interesting examples.

Phishing and Spikes

One of the recent samples we have found was a Facebook phishing campaign that was surfaced by our real-time alert system. Our ...

BSides Las Vegas, Black Hat, and Defcon Wrap-up

For OpenDNS, the first week of August was fun but also busy. A group of us OpenDNS researchers and engineers headed to Las Vegas for BSides Las Vegas, Black Hat, and Defcon. We gave talks, attended sessions, met with prospects and customers, and caught up with infosec friends.

This blog post details some of the insights from those who attended.

Insights from Andrew Hess

At BSides Las Vegas, Andrew Hess gave a short presentation about an internal feature the OpenDNS engineering team has constructed, and ...

Virtual Reality : Thoughts about the Future of Data Visualization.

Full immersive experience in a virtual world has always been a source of interest in litterature, movies, and technology. Famous cyberpunk writers such as William Gibson in Neuromancer or Neal Stephenson in Snowcrash have explored the concept artisticly. Many movies have attempted to represent the infinite possibilities and dangers of virtual reality : The Matrix, Tron, Hackers, and so many others. A lot of us still remember the days of the mighty Power Glove and the first adaptations to video ...
