An exploit was released for a flaw existing in a process in CPUs called Simultaneous Multithreading (SMT). Continue reading PortSmash Side-Channel Attack Siphons Data From Intel, Other CPUs
I’m working on a document about them and I think I understand it general what happens -> by exploiting the CPUs memory caching and speculative execution but I’m a little lost of how protected data is actually exposed.
So if… Continue reading Can someone explain in layman terms how Spectre and Meltdown expose protected data
A massive performance hit is the most noticeable side-effect of the Spectre fixes that Microsoft has had to release this year.
The post Microsoft Allegedly Overcomes Performance Issues in its Spectre Fixes appeared first on Thurrott.com.

I don’t know all the details of Spectre and Meltdown, but the way I understand it is that they allow reading from memory, not writing to it. Also, I read that at least Spectre can get out of the virtual machine and therefore also affect th… Continue reading Mitigation of Spectre and Meltdown affecting host OS from guest OS (Virtualbox)
New Intel Coffee Lake CPUs offer hardware-based protections against some -but not all- Spectre and Meltdown variants. Continue reading New Ninth-Gen Intel CPUs Shield Against Some Spectre, Meltdown Variants
It’s only September and yet 2018 is well on its way to being remembered as the year of fixing flaws we didn’t realise were possible in hardware we’d never heard of. Continue reading Intel releases firmware update for ME flaw
Since the discovery of Meltdown and Spectre, CPU security has been compromised and trust to the main manufacturers reduced, particularly Intel. 8 months later I wonder, what CPUs are more secure at this moment?
Why? Have the patches achie… Continue reading Are new AMD processors more secure than Intel ones?
I didn’t follow all the episodes about backdoors in Intel CPUs
What can intelligence or law enforcement agencies potentially do on a computer equipped with a vulnerable Intel CPU (connected to the Internet but not directly – behind a rout… Continue reading Privacy implications of Intel CPU backdoors [closed]
In the light of all the recent Intel Vulnerabilities with speculative execution, can speculative execution be fully disabled to protect from all this vulnerabilities, from BIOS or OS kernel?
Maybe stupid question, but is it… Continue reading Can speculative execution on intel cpu be disabled?
For Intel and more than a billion computers with Intel CPUs, the microprocessor flaws just keep coming. Continue reading ‘Foreshadow’ flaw found in Intel CPUs – what to do
