The NSA Warns of TLS Inspection

The NSA has released a security advisory warning of the dangers of TLS inspection: Transport Layer Security Inspection (TLSI), also known as TLS break and inspect, is a security process that allows enterprises to decrypt traffic, inspect the decrypted content for threats, and then re-encrypt the traffic before it enters or leaves the network. Introducing this capability into an enterprise… Continue reading The NSA Warns of TLS Inspection

Russians Hack FBI Comms System

Yahoo News reported that the Russians have successfully targeted an FBI communications system: American officials discovered that the Russians had dramatically improved their ability to decrypt certain types of secure communications and had successfully tracked devices used by elite FBI surveillance teams. Officials also feared that the Russians may have devised other ways to monitor U.S. intelligence communications, including hacking… Continue reading Russians Hack FBI Comms System

Traffic Analysis of the LTE Mobile Standard

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. EDITED TO ADD (7/3): More information. I have been thinking about this, and now believe the attacks are more serious than… Continue reading Traffic Analysis of the LTE Mobile Standard

Detecting Drone Surveillance with Traffic Analysis

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 … Continue reading Detecting Drone Surveillance with Traffic Analysis

Detecting Drone Surveillance with Traffic Analysis

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, say — someone might want… Continue reading Detecting Drone Surveillance with Traffic Analysis

More on the NSA’s Use of Traffic Shaping

"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 not be able to monitor…. Continue reading More on the NSA’s Use of Traffic Shaping
