This article describes how there exist various vulnerabilities in computing hardware that adversaries can exploit to mount attacks against the users of such hardware. Microarchitectural attacks, the result of these vulnerabilities, take advantage of microarchitectural performance of processor implementations, revealing hidden computing process. Leveraging microarchitectural resources, adversaries can potentially launch timing-based side-channel attacks in order to leak information via timing. In view of these security threats against computing hardware, the authors analyse current attacks that take advantage of microarchitectural elements in shared computing hardware. This analysis focuses only on timing-based side-channel attacks against the components of modern PC platforms - with references being made also to other platforms when relevant - as opposed to any other variations of side-channel attacks which have a broad application range. To this end, the authors analyse timing attacks performed against processor and cache components, again with references to other components when appropriate.
