Reading Time: 4 minutes This is the year of the security threats originated by hardware level bugs. The year has begun with the Spectre and Metldown bug with several months of possible solutions, new BIOS, new patches… and new variants of those bugs (like Spectre V4 and V5). But we are far from the solution because other bugs came out. And more will come out… All the software used at the microprocessor level and all the optimizations will probably be a good vector for new attack patterns. As already written, we are still far from the solution.
