After reading several in-depth analysis of this vulnerability and then trying to explain my non-tech friends what this is all is about (disclaimer: I'm just a developer and don't work with assembly, processors or security), I have to admit that it's a pretty awesome executive summary of the issue for a non-technical reader.
- ptaipale 9y agoIt's slightly wrong, proposal for improvement: Spectre fools the processor into running speculative operations -- ones that it usually executes "just in case" and then throws the result away if it is not needed -- and then uses information about how long the hardware takes to retrieve the data to infer the details of that information.
