What is the difference between Meltdown and Spectre? Which cloud providers are affected by Meltdown?Ĭloud providers which use Intel CPUs and Xen PV as virtualization without having patches applied.įurthermore, cloud providers without real hardware virtualization, relying on containers that share one kernel, such as Docker, LXC, or OpenVZ are affected. In particular, we have verified Spectre on Intel, AMD, and ARM processors. More specifically, all modern processors capable of keeping many instructions in flight are potentially vulnerable. Which systems are affected by Spectre?Īlmost every system is affected by Spectre: Desktops, Laptops, Cloud Servers, as well as Smartphones. According to ARM, some of their processors are also affected. At the moment, it is unclear whether AMD processors are also affected by Meltdown. Currently, we have only verified Meltdown on Intel processors. We successfully tested Meltdown on Intel processor generations released as early as 2011.
More technically, every Intel processor which implements out-of-order execution is potentially affected, which is effectively every processor since 1995 (except Intel Itanium and Intel Atom before 2013). Which systems are affected by Meltdown?ĭesktop, Laptop, and Cloud computers may be affected by Meltdown.

There is also work to harden software against future exploitation of Spectre, respectively to patch software after exploitation through Spectre ( LLVM patch, MSVC, ARM speculation barrier header). There are patches against Meltdown for Linux ( KPTI (formerly KAISER)), Windows, and OS X. Has Meltdown or Spectre been abused in the wild? This may include passwords and sensitive data stored on the system. If your system is affected, our proof-of-concept exploit can read the memory content of your computer. However, your antivirus may detect malware which uses the attacks by comparing binaries after they become known. Unlike usual malware, Meltdown and Spectre are hard to distinguish from regular benign applications.
While possible in theory, this is unlikely in practice. Can my antivirus detect or block this attack? The exploitation does not leave any traces in traditional log files. Can I detect if someone has exploited Meltdown or Spectre against me? Questions & Answers Am I affected by the vulnerability?
