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?
22219 PID was consuming constant 99~101% cpu. It is java process for tomcat. After that I checked and found that lwp 24933 was consuming most of the cpu. Below is status of that.

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?
I know what is real and protected mode of cpu execution. But how CPU implements protected mode ? AFAIK cpu does everything what the program says it to do. Where is the protected mode behaviour implemented ? Does OS plays any … Continue reading How protected mode in CPU is really implemented?
Several execution vulnerabilities has been detected to affect Intel Processors. The vulnerabilities which were detected so far have been reported to be an execution type of flaws and were quickly named Foreshadow. The vulnerabiltities aim to gain contr… Continue reading How to Stop an Intel Foreshadow Bug Exploit Attack

Security fraternity is still dealing with the adverse consequences and versatile range of threats caused by the Spectre and Meltdown vulnerabilities. But, to add to their misery, there is another possibly worst hardware flaw detected by securi… Continue reading New Intel chip flaw “Foreshadow” attacks SGX technology to extract sensitive data
It’s been at least a month or two since the last vulnerability in Intel CPUs was released, but this time it’s serious. Foreshadow is the latest speculative execution attack that allows balaclava-wearing hackers to steal your sensitive information. You know it’s a real 0-day because it already has a domain, a logo, and this time, there’s a video explaining in simple terms anyone can understand why the sky is falling. The video uses ukuleles in the sound track, meaning it’s very well produced.
The Foreshadow attack relies on Intel’s Software Guard Extension (SGX) instructions that allow user code to allocate …read more
