Interesting research in using traffic analysis to learn things about encrypted traffic. It’s hard to know how critical these vulnerabilities are. They’re very hard to close without wasting a huge amount of bandwidth. The active attacks are more interesting. Powered by WPeMatico
This is clever: Researchers at Ben Gurion University in Beer Sheva, Israel have built a proof-of-concept system for counter-surveillance against spy drones that demonstrates a clever, if not exactly simple, way to determine whether a certain person or object is under aerial surveillance. They first generate a recognizable pattern on whatever subject — a window, … Read More “Detecting Drone Surveillance with Traffic Analysis” »
“Traffic shaping” — the practice of tricking data to flow through a particular route on the Internet so it can be more easily surveiled — is an NSA technique that has gotten much less attention than it deserves. It’s a powerful technique that allows an eavesdropper to get access to communications channels it would otherwise … Read More “More on the NSA’s Use of Traffic Shaping” »
