I would like to create something like this on my own. But I’m not certain about it’s implementation.
Does their bytecode interpreter converts it back to original machine c… Continue reading How code virtualizers like oreans code virtualizer are implemented
We know about short-term measures to mitigate the Meltdown and Spectre vulnerabilities in certain microprocessors where speculative execution has measurable effects on cache timings (mainly patches to microcode, operating systems and any a… Continue reading How can CPU designers prevent information leaks from speculated execution?
Intel says its firmware updates for Meltdown and Spectre are causing additional reboots and hits to performance. Continue reading Intel Says Firmware Fixes for Spectre and Meltdown Affecting Newer Chips

This blog reviews the details of Meltdown and discusses the inherent immunity for end users provided by Bromium’s architecture. Meltdown is an Intel CPU vulnerability leveraging speculative execution which gives an attacker-controlled process the… Continue reading Anatomy of Meltdown – A Technical Journey
As far as I understand, with Spectre, a malicious attacker from userland (javascript from webbrowser) can read “kernel memory”.
But the question is: what is in the kernel memory, that can cause any security/privacy problem?… Continue reading What privacy/security problems occur if a userland process can read the kernel memory?
TL;DR – Spectre and Meltdown are two recently announced vulnerabilities that allow private data to be accessed by otherwise unauthorized applications. Patches are coming out to mitigate risks, but these may also affect the speed of your devices a… Continue reading Spectre and Meltdown Haunt CPUs Everywhere – What to Know and What to Do
Recently Intel has claimed the following in a press release (emphasis added):
SANTA CLARA, Calif., Jan. 4, 2018 — Intel has developed and is rapidly issuing updates for all types of Intel-based computer systems — includin… Continue reading Intel firmware/microcode updates that make processors "immune" to both Spectre and Meltdown?
