Yet another way of eavesdropping on someone’s computer activity: using the webcam microphone to "listen" to the computer’s screen…. Continue reading Eavesdropping on Computer Screens through the Webcam Mic
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 bel… Continue reading Speculation Attack Against Intel’s SGX
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 demonstrates how speculative execution can… Continue reading Speculation Attack Against Intel’s SGX
Researchers at the University of California, Irvine, are able to recover user passwords by way of thermal imaging. The tech is pretty straightforward, but it’s interesting to think about the types of scenarios in which it might be pulled off. Abstract:… Continue reading Recovering Keyboard Inputs through Thermal Imaging
Researchers at the University of California, Irvine, are able to recover user passwords by way of thermal imaging. The tech is pretty straightforward, but it’s interesting to think about the types of scenarios in which it might be pulled off. Abstract: As a warm-blooded mammalian species, we humans routinely leave thermal residues on various objects with which we come in… Continue reading Recovering Keyboard Inputs through Thermal Imaging
Google and Microsoft researchers have disclosed another Spectre-like CPU side-channel vulnerability, called "Speculative Store Bypass." Like the others, the fix will slow the CPU down. The German tech site Heise reports that more are coming. I’m not surprised. Writing about Spectre and Meltdown in January, I predicted that we’ll be seeing a lot more of these sorts of vulnerabilities. Spectre… Continue reading Another Spectre-Like CPU Vulnerability
When Spectre and Meltdown were first announced earlier this year, pretty much everyone predicted that there would be many more attacks targeting branch prediction in microprocessors. Here’s another one: In the new attack, an attacker primes the PHT and… Continue reading Another Branch Prediction Attack
When Spectre and Meltdown were first announced earlier this year, pretty much everyone predicted that there would be many more attacks targeting branch prediction in microprocessors. Here’s another one: In the new attack, an attacker primes the PHT and running branch instructions so that the PHT will always assume a particular branch is taken or not taken. The victim code… Continue reading Another Branch Prediction Attack
Nice profile of Mordechai Guri, who researches a variety of clever ways to steal data over air-gapped computers. Guri and his fellow Ben-Gurion researchers have shown, for instance, that it’s possible to trick a fully offline computer into leaking data… Continue reading Jumping Air Gaps
Nice profile of Mordechai Guri, who researches a variety of clever ways to steal data over air-gapped computers. Guri and his fellow Ben-Gurion researchers have shown, for instance, that it’s possible to trick a fully offline computer into leaking data to another nearby device via the noise its internal fan generates, by changing air temperatures in patterns that the receiving… Continue reading Jumping Air Gaps
