Really interesting research: “Lend Me Your Ear: Passive Remote Physical Side Channels on PCs.” Abstract: We show that built-in sensors in commodity PCs, such as microphones, inadvertently capture electromagnetic side-channel leakage from ongoing computation. Moreover, this information is often conveyed by supposedly-benign channels such as audio recordings and common Voice-over-IP applications, even after lossy compression. … Read More “Side Channels Are Common” »

This clever attack allows someone to uniquely identify a phone when you visit a website, based on data from the accelerometer, gyroscope, and magnetometer sensors. We have developed a new type of fingerprinting attack, the calibration fingerprinting attack. Our attack uses data gathered from the accelerometer, gyroscope and magnetometer sensors found in smartphones to construct … Read More “Fingerprinting iPhones” »

Interesting research: The trick in accurately tracking a person with this method is finding out what kind of activity they’re performing. Whether they’re walking, driving a car, or riding in a train or airplane, it’s pretty easy to figure out when you know what you’re looking for. The sensors can determine how fast a person … Read More “Tracking People Without GPS” »

Websites are sending information prematurely: …we discovered NaviStone’s code on sites run by Acurian, Quicken Loans, a continuing education center, a clothing store for plus-sized women, and a host of other retailers. Using Javascript, those sites were transmitting information from people as soon as they typed or auto-filled it into an online form. That way, … Read More “Websites Grabbing User-Form Data Before It’s Submitted” »

There has been a flurry of research into using the various sensors on your phone to steal data in surprising ways. Here’s another: using the phone’s ambient light sensor to detect what’s on the screen. It’s a proof of concept, but the paper’s general conclusions are correct: There is a lesson here that designing specifications … Read More “Stealing Browsing History Using Your Phone’s Ambient Light Sensor” »

Interesting acoustic attack against the MEMS accelerometers in devices like FitBits. Millions of accelerometers reside inside smartphones, automobiles, medical devices, anti-theft devices, drones, IoT devices, and many other industrial and consumer applications. Our work investigates how analog acoustic injection attacks can damage the digital integrity of the capacitive MEMS accelerometer. Spoofing such sensors with intentional … Read More “Acoustic Attack Against Accelerometers” »
