Another month, another speculative execution vulnerability found in Intel processors. If your computer is running any modern Intel CPU built before October 2018, it’s likely vulnerable to a newly discovered hardware issue that could allow attackers to leak sensitive data from the OS kernel, co-resident virtual machines, and even from Intel’s secured SGX enclave. Dubbed …

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 …

Unlike previous side-channel vulnerabilities disclosed in Intel CPUs, researchers have discovered a new flaw that can be exploited remotely over the network without requiring an attacker to have physical access or any malware installed on a targeted computer. Dubbed NetCAT, short for Network Cache ATtack, the new network-based side-channel vulnerability could allow a remote attacker …

A new variant of the Spectre (Variant 1) side-channel vulnerability has been discovered that affects modern Intel CPUs which leverage speculative-execution, and some AMD processors as well, Microsoft and Red Hat warn. Identified as CVE-2019-1125, the vulnerability could allow unprivileged local attackers to access sensitive information stored in the operating system privileged kernel memory, including passwords, …

Google has reportedly suspended all businesses with the world’s second-biggest smartphone maker, Huawei, and revoked its Android license effective immediately—a move that will have a drastic impact on Huawei devices across the globe. Revoking Android license means Huawei future smartphones will no longer have access to Android updates and apps like Gmail or the Play …

Academic researchers today disclosed details of the newest class of speculative execution side-channel vulnerabilities in Intel processors that impacts all modern chips, including the chips used in Apple devices. After the discovery of Spectre and Meltdown processor vulnerabilities earlier last year that put practically every computer in the world at risk, different classes of Spectre …

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 …

Intel Skylake die shot. Researchers have found a way to run malicious code on systems with Intel processors in such a way that the malware can’t be analyzed or identified by antivirus software, using the processor’s own features to protect the bad code. As well as making malware in general harder to examine, bad actors …

Disclosed earlier this year, potentially dangerous Meltdown and Spectre vulnerabilities that affected a large family of modern processors proven that speculative execution attacks can be exploited in a trivial way to access highly sensitive information. Since then, several more variants of speculative execution attacks have been discovered, including Spectre-NG, SpectreRSB, Spectre 1.1, Spectre1.2, TLBleed, Lazy …

A team of security researchers has discovered another serious side-channel vulnerability in Intel CPUs that could allow an attacker to sniff out sensitive protected data, like passwords and cryptographic keys, from other processes running in the same CPU core with simultaneous multi-threading feature enabled. The vulnerability, codenamed PortSmash (CVE-2018-5407), has joined the list of other …
