One of the pioneering companies was G Data, a German company that in 1987 developed a product to safeguard Atari computers.

The first commercial antivirus software programs hit the stores shortly after. Prior to the 1980s, some experiments had been conducted with programs able to automatically spread between computers, but it was during this decade when the first viruses capable of deleting data or disabling systems were created and launched. The history of antivirus software is, of course, linked to the history of computer viruses or 'malware'. But, do we take advantage of all the possibilities that AV software offers? This article reviews the main features of this type of security software that you should be aware of to make the most of them. Users are familiar with the updates that are periodically executed.

Yes, there is a GitHub repository containing test code for Meltdown.Nowadays, it’s hard to find a personal or corporate computers that doesn’t run some sort of antivirus software.

Can I see Meltdown in action?īoth the Meltdown and Spectre logo are free to use, rights waived via CC0. CVE is the Standard for Information Security Vulnerability Names maintained by MITRE. What is the CVE-2017-5754?ĬVE-2017-5754 is the official reference to Meltdown. Furthermore, there is a Google Project Zero blog entry about both attacks. Yes, there is an academic paper and a blog post about Meltdown, and an academic paper about Spectre. Is there more technical information about Meltdown and Spectre? As it is not easy to fix, it will haunt us for quite some time. The name is based on the root cause, speculative execution. The vulnerability basically melts security boundaries which are normally enforced by the hardware. Spectre tricks other applications into accessing arbitrary locations in their memory.īoth attacks use side channels to obtain the information from the accessed memory location.įor a more technical discussion we refer to the papers ( Meltdown and Spectre) Why is it called Meltdown? Meltdown breaks the mechanism that keeps applications from accessing arbitrary system memory.Ĭonsequently, applications can access system memory. 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?
