Experts have successfully tested an attack on three Intel chips, Sandy Bridge, Haswell and Skylake. This shows that the BranchScope can still be exploited on machines that have installed recently released patches for both Specter and Meltdown attacks.

Similar to Specter One, BranchScope technology targets branch prediction mechanisms (BPUs) implemented by processors to improve the performance of chips.
