Speculative execution side channels, on the other hand, represented a fundamentally new hardware vulnerability class with no established process for determining their severity and their impact on existing software security models. This ultimately led to the mobilization of hundreds of individuals across the company, but before we could get there, we needed to assess the severity, impact, and root cause of the issue.Д¬onventional software vulnerabilities are well-understood and are relatively easy to perform root cause analysis on (we even have automation for many cases, see VulnScan). Given the potential severity and the scope of these attacks, we kicked off our incident response process to drive coordination and remediation across Microsoft and with industry partners. We first learned about speculative execution side channel vulnerabilities through the discoveries made by Jann Horn of Google Project Zero. Please note that the information in this post is current as of the date of this post.

If you are interested in more general guidance, please refer to our knowledge base articles for Windows Server, Windows Client, and Microsoft cloud services. This post is primarily geared toward security researchers and engineers who are interested in deeper technical details related to speculative execution side channel vulnerabilities and their respective mitigations. WeвЂ™ll do this by briefly describing how we investigated this new vulnerability class, the taxonomy we established for reasoning about it, and the mitigations we have implemented as a result. In this post, weвЂ™ll provide insight into how Microsoft has approached mitigating speculative execution side channel hardware vulnerabilities to date. Mitigating hardware vulnerabilities through changes in firmware and software is a significant industry challenge, and there has been some confusion over the past two months for users as the industry has collectively continued to work on this.

This new hardware vulnerability class represents a major advancement in CPU side channel attacks and weвЂ™re sincerely grateful to the researchers who discovered these issues, our industry partners, and the many individuals across Microsoft who have worked on these vulnerabilities. If you havenвЂ™t had a chance to learn about these issues, we recommend watching The Case of Spectre and Meltdown by the team at TU Graz from BlueHat Israel, reading the blog post by Jann Horn ( of Google Project Zero, or reading the FOSDEM 2018 presentation by Jon Masters of Red Hat. On January 3 rd, 2018, Microsoft released an advisory and security updates related to a newly discovered class of hardware vulnerabilities involving speculative execution side channels (known as Spectre and Meltdown) that affect AMD, ARM, and Intel CPUs to varying degrees.
