Move over, Meltdown and Spectre. A new “Foreshadow” attack, alternatively called L1 Terminal Fault or L1TF, targets Intel’s Security Guard Extensions (SGX) within its Core chips.
You should be safe, though, if you’ve already patched your PC as part of the earlier Spectre and Meltdown mitigations that rolled out over the course of the year, according to a blog post from Intel, which disclosed the flaw today. (Wired has more of the technical backstory on the bug itself, and Intel has published a video explaining the issue.) Microsoft is also rolling out patches, Intel said.
