New PlunderVolt Attack Targets Intel SGX Enclaves by Tweaking CPU Voltage

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 compromised.Dubbed Plundervolt and tracked as CVE-2019-11157, the attack relies on the fact that modern processors allow frequency and voltage to be

Researchers Implant “Protected” Malware On Intel SGX Enclaves

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 words, the technique allows attackers to implant malware code in a secure memory that uses protection features of SGX which are otherwise
