TEE.Fail attack breaks confidential computing on Intel, AMD, NVIDIA CPUs
Academic researchers developed a side-channel attack called TEE.Fail, which allows extracting secrets from the trusted execution environment in the CPU, the highly secure area of a system, such as Intel’s SGX and TDX, and AMD’s SEV-SNP. The method is a memory-bus interposition attack on DDR5 systems that could be successfully done by computer hobbyists a cost of less than […]
New VMScape attack breaks guest-host isolation on AMD, Intel CPUs
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. The attack breaks the isolation between VMs and the cloud hypervisor, bypassing existing Spectre mitigations and threatening to leak sensitive data by leveraging speculative execution. The […]
