    a new intel-specific CPU vulnerability has been discovered: https://www.cyberus-technology.de/posts/2019-05-14-zombieload.html

    quick facts:
    - can be used to leak data between processes, hyperthreads, SGX enclaves, etc
    - effects core and xeon CPUs
    - CPUs with meltdown mitigations are less effected, but still vulnerable
    - this is a hardware issue - OS independent
    - can be mitigated by disabling hyperthreading
    - proof of concept - one thread is able to access URLs typed into firefox (a different thread)
