When first discovered in 2010, the Stuxnet computer worm posed a baffling puzzle. Beyond its sophistication loomed a more troubling mystery: its purpose. Ralph Langner and team helped crack the code that revealed this digital warhead's final target. In a fascinating look inside cyber-forensics, he explains how -- and makes a bold (and, it turns ...

Chris Domas is a cybersecurity researcher, operating on what's become a new front of war, "cyber." In this engaging talk, he shows how researchers use pattern recognition and reverse engineering (and pull a few all-nighters) to understand a chunk of binary code whose purpose and contents they don't know.

The Internet has transformed the front lines of war, and it's leaving governments behind. As security analyst Rodrigo Bijou shows, modern conflict is being waged online between non-state groups, activists and private corporations, and the digital landscape is proving to be fertile ground for the recruitment and radicalization of terrorists. Mean...

Modern turtle shells are almost as diverse as the turtles themselves. Sea turtles have flatter, lighter shells for gliding through the water. Land-dwelling tortoises have domed shells that can slip free of predators' jaws. Leatherback turtles have shells without the ring of bone around the edge. So how did the shell evolve? Judy Cebra-Thomas exp...

Nations can now attack other nations with cyber weapons: silent strikes on another country's computer systems, power grids, dams that leave no trace behind. (Think of the Stuxnet worm.) Guy-Philippe Goldstein shows how cyberattacks can leap between the digital and physical worlds to prompt armed conflict -- and how we might avert this global sec...

Mikko Hypponen lays it out: "The talks I chose for my playlist are about technology, security or privacy. Because geeks. Then I added the talk from Dan Barber. Because fish."
