Cyberattacks are getting smarter and harder to stop. This week, hackers used sneaky tools, tricked trusted systems, and quickly took advantage of new security problems—some just hours after being found. No system was fully safe
A new Spectre-like attack dubbed VMScape allows a malicious virtual machine (VM) to leak cryptographic keys from an unmodified QEMU hypervisor process running on modern AMD or Intel CPUs. [...]
AMD Zen hardware and Intel Coffee Lake affected If you thought the world was done with side-channel CPU attacks, think again. ETH Zurich has identified yet another Spectre-based transient execution vulnerability that affects AMD Zen CPUs and Intel Coffee Lake processors by breaking virtualization boundaries.…
Researchers from the Vrije Universiteit Amsterdam have disclosed a new side-channel attack called SLAM that could be exploited to leak sensitive information from kernel memory on current and upcoming CPUs from Intel, AMD, and Arm
A group of researchers has revealed details of a new vulnerability affecting Intel CPUs that enables attackers to obtain encryption keys and other secret information from the processors
With speculative execution attacks remaining a stubbornly persistent vulnerability ailing modern processors, new research has highlighted an "industry failure" to adopting mitigations released by AMD and Intel, posing a firmware supply chain threat
Speculative execution side-channels continue to haunt silicon world Older AMD and Intel chips are vulnerable to yet another Spectre-based speculative-execution attack that exposes secrets within kernel memory despite defenses already in place. Mitigating this side channel is expected to take a toll on performance.…
Plus: Intel, AMD react to Hertzbleed data-leaking holes in CPUs Patch Tuesday Microsoft claims to have finally fixed the Follina zero-day flaw in Windows as part of its June Patch Tuesday batch, which included security updates to address 55 vulnerabilities.…
Researchers have disclosed a new technique that could be used to circumvent existing hardware mitigations in modern processors from Intel, AMD, and Arm and stage speculative execution attacks such as Spectre to leak sensitive information from host memory
