What CPUs does the Spoiler attack affect?
I see on different websites different information about the Spoiler Attack. Some websites say all Intel CPUs are vulnerable and other websites say only Intel Core CPUs are vulnerable.
Are Intel Xeon CPUs vulnerable?
RSAC 2019: Picking Apart the Foreshadow Attack
Raoul Strackx, one of the researchers who discovered the Foreshadow speculative execution vulnerability, talks at RSA about the Catch-22 issue when it comes to fixing speculative execution flaws. Continue reading RSAC 2019: Picking Apart the Foreshadow Attack
Google: Software is never going to be able to fix Spectre-type bugs
Researchers also devise a Spectre-like attack with no known mitigation. Continue reading Google: Software is never going to be able to fix Spectre-type bugs
Is it possible to completely prevent Speculative Execution Side-Channel attacks?
I’m learning about computer architecture recently, and I heard that branch prediction is really tricky but may improve the efficiency of cpu a lot, then I came across this term. My question is that is it possible to completel… Continue reading Is it possible to completely prevent Speculative Execution Side-Channel attacks?
7 New Meltdown and Spectre-type CPU Flaws Affect Intel, AMD, ARM CPUs
Disclosed earlier this year, potentially dangerous Meltdown and Spectre vulnerabilities that affected a large family of modern processors proven that speculative execution attacks can be exploited in a trivial way to access highly sensitive information… Continue reading 7 New Meltdown and Spectre-type CPU Flaws Affect Intel, AMD, ARM CPUs
Spectre, Meltdown researchers unveil 7 more speculative execution attacks
Systemic analysis reveals a range of new issues, and a need for new mitigations. Continue reading Spectre, Meltdown researchers unveil 7 more speculative execution attacks
Do any speculative executation attacks affect ARMv7 CPUs?
Do we know if there are speculative execution attacks that affect ARMv7 CPUs at this time? Are there any theoretical risks that need further investigation?
Continue reading Do any speculative executation attacks affect ARMv7 CPUs?
Security Boulevard’s 5 Most Read Stories for the Week, August 13-17
A new week, a new crop of security stories. Last week, lack of user privacy, man-in-the-attack, dumb privacy rules and Intel CPUs vulnerabilities made the headlines. In addition, we discussed how to get smarter about securing smart technologies. Be su… Continue reading Security Boulevard’s 5 Most Read Stories for the Week, August 13-17
