New ‘CacheOut’ Attack Leaks Data from Intel CPUs, VMs and SGX Enclave
Another month, another speculative execution vulnerability found in Intel processors.
If your computer is running any modern Intel CPU built before October 2018, it’s likely vulnerable to a newly discovered hardware issue that could allow attackers to… Continue reading New ‘CacheOut’ Attack Leaks Data from Intel CPUs, VMs and SGX Enclave
Can Applications Withstand the ZombieLoad Attack?
As if Meltdown, Spectre and Foreshadow were not enough, recently a new critical vulnerability called ZombieLoad has been discovered that affects a series of modern Intel processors. This vulnerability enables a potential attacker to read small pieces … Continue reading Can Applications Withstand the ZombieLoad Attack?
New ZombieLoad v2 Attack Affects Intel’s Latest Cascade Lake CPUs
Zombieload is back.
This time a new variant (v2) of the data-leaking side-channel vulnerability also affects the most recent Intel CPUs, including the latest Cascade Lake, which are otherwise resistant against attacks like Meltdown, Foreshadow and oth… Continue reading New ZombieLoad v2 Attack Affects Intel’s Latest Cascade Lake CPUs
Sushi Roll Helps Inspect Your CPU Internals
[Gamozolabs’] post about Sushi Roll — a research kernel for monitoring Intel CPU internals — is pretty long. While we were disappointed at the end that the kernel’s source is not exactly available due to “sensitive features”, we were so impressed with the description of the modern x86 architecture and …read more

A new exploit in town: SWAPGS. How and why did it happen?
Apparently, there’s a new speculative execution exploit in town on Intel CPUs: SWAPGS. It takes research on Meltdown and Spectre to the next level and targets the root of the CPU.
This is not the first SE exploit, and probab… Continue reading A new exploit in town: SWAPGS. How and why did it happen?
SWAPGS Attack — New Speculative Execution Flaw Affects All Modern Intel CPUs
A new variant of the Spectre (Variant 1) side-channel vulnerability has been discovered that affects all modern Intel CPUs, and probably some AMD processors as well, which leverage speculative execution for high performance, Microsoft and Red Hat warne… Continue reading SWAPGS Attack — New Speculative Execution Flaw Affects All Modern Intel CPUs
