| Titre | The second Meltdown: New Intel CPU attacks leak secrets |
| Texte | Researchers have found new flaws in Intel processors that could allow hackers to defeat the security boundaries enforced by virtual machine hypervisors, operating system kernels and Intel SGX enclaves, putting data on both servers and endpoint systems at risk. The new attack techniques can be used to leak sensitive secrets like passwords or encryption keys from protected memory regions and are not blocked by mitigations for past CPU attacks.[ Keep up with 8 hot cyber security trends (and 4 going cold). Give your career a boost with top security certifications: Who they're for, what they cost, and which you need. | Sign up for CSO newsletters. ] Over a year ago, the Meltdown and Spectre attacks took the computer industry by storm and showed that the memory isolation between the operating system kernel and unprivileged applications or between different virtual machines running on the same server were not as impervious as previously thought. Those attacks took advantage of a performance enhancing feature of modern CPUs called speculative execution to steal secrets by analyzing how data was being accessed inside CPU caches. |
