The Intel attack uses a similar technique that gamers commonly use to overclock their CPUs. Continue reading Modern Intel CPUs Plagued By Plundervolt Attack
A team of cybersecurity researchers demonstrated a novel yet another technique to hijack Intel SGX, a hardware-isolated trusted space on modern Intel CPUs that encrypts extremely sensitive data to shield it from attackers even when a system gets compro… Continue reading New PlunderVolt Attack Targets Intel SGX Enclaves by Tweaking CPU Voltage
Are secure enclaves like intel SGX protected from memory leaks? What if a non trusted privileged user dumps all the physical RAM memory. Is it possible to extract the keys in this way?

Cybersecurity researchers have discovered a way to hide malicious code in Intel SGX enclaves, a hardware-based memory encryption feature in modern processors that isolates sensitive code and data to protect it from disclosure or modification.
In other… Continue reading Researchers Implant “Protected” Malware On Intel SGX Enclaves
I have been looking into SGX (Intel’s Software Guard Extension) for the last few days. It sounds like a very useful technology with some significant security advantages for many pieces of software. However, I have yet to identify a single … Continue reading Does SGX provide a significant benefit for desktop operating systems?
