New research is able to recover sound waves in a room by observing minute changes in the room’s light bulbs. This technique works from a distance, even from a building across the street through a window. Details: In an experiment using three different telescopes with different lens diameters from a distance of 25 meters (a … Read More “Eavesdropping on Sound Using Variations in Light Bulbs” »
Remember Spectre and Meltdown? Back in early 2018, I wrote: Spectre and Meltdown are pretty catastrophic vulnerabilities, but they only affect the confidentiality of data. Now that they — and the research into the Intel ME vulnerability — have shown researchers where to look, more is coming — and what they’ll find will be worse … Read More “Another Intel Speculative Execution Vulnerability” »
I previously wrote about hacking voice assistants with lasers. Turns you can do much the same thing with ultrasonic waves: Voice assistants — the demo targeted Siri, Google Assistant, and Bixby — are designed to respond when they detect the owner’s voice after noticing a trigger phrase such as ‘Ok, Google’. Ultimately, commands are just … Read More “Hacking Voice Assistants with Ultrasonic Waves” »
Not that serious, but interesting: In late 2011, Intel introduced a performance enhancement to its line of server processors that allowed network cards and other peripherals to connect directly to a CPU’s last-level cache, rather than following the standard (and significantly longer) path through the server’s main memory. By avoiding system memory, Intel’s DDIOshort for … Read More “Another Side Channel in Intel Chips” »

Yet another side-channel attack on smartphones: “Hearing your touch: A new acoustic side channel on smartphones,” by Ilia Shumailov, Laurent Simon, Jeff Yan, and Ross Anderson. Abstract: We present the first acoustic side-channel attack that recovers what users type on the virtual keyboard of their touch-screen smartphone or tablet. When a user taps the screen … Read More “Recovering Smartphone Typing from Microphone Sounds” »
It’s only a prototype, but this USB cable has an embedded Wi-Fi controller. Whoever controls that Wi-Fi connection can remotely execute commands on the attached computer. Powered by WPeMatico
It’s amazing that this is even possible: “SonarSnoop: Active Acoustic Side-Channel Attacks“: Abstract: We report the first active acoustic side-channel attack. Speakers are used to emit human inaudible acoustic signals and the echo is recorded via microphones, turning the acoustic system of a smart phone into a sonar system. The echo signal can be used … Read More “Using a Smartphone’s Microphone and Speakers to Eavesdrop on Passwords” »
Yet another way of eavesdropping on someone’s computer activity: using the webcam microphone to “listen” to the computer’s screen. Powered by WPeMatico
Another speculative-execution attack against Intel’s SGX. At a high level, SGX is a new feature in modern Intel CPUs which allows computers to protect users’ data even if the entire system falls under the attacker’s control. While it was previously believed that SGX is resilient to speculative execution attacks (such as Meltdown and Spectre), Foreshadow … Read More “Speculation Attack Against Intel’s SGX” »
