    @vilmibm people take it for granted now that you can just click on things, but it took decades for the idea to take hold & become ubiquitous. Most of it was utterly awful until the web came along.

    Interesting paper.

    "We found 4 new cross-domain leaks, successfully detected all 6 known leaks possible in the configurations that we
    tested and reproduced 6 known flaws in patches."

    e.g.:

    "We discovered a microarchitectural effect on AMD3 that allows an attacker VM to selectively infer any bit from the memory of another VM, provided the victim VM has previously accessed (i.e., cached) this bit. By repeatedly exploiting this effect, the attacker VM could read the victim’s memory one bit at a time, and thus learn the contents of an arbitrary memory range used by the victim. "

      Enter, Exit, Page Fault, Leak: Testing Isolation Boundaries for Microarchitectural Leaks - Microsoft Research
      from Boris Köpf
      CPUs provide isolation mechanisms like virtualization and privilege levels to protect software. Yet these focus on architectural isolation while typically overlooking microarchitectural side channels, exemplified by Meltdown and Foreshadow. Software must therefore supplement architectural defenses with ad-hoc microarchitectural patches, which are constantly evolving as new attacks emerge and defenses are proposed. Such reactive approach makes […]

    @Gina yes, or you could replace the wires in that connector with longer ones. Looks like 240v? That is potentially deadly, FYI.
