    MUHAHAHAHAHAHA, yet another bug, yet another Intel one and yet another one which doesnt bother AMD if I read this correctly:

    https://cacheoutattack.com/

    Access to everything, the golden key. Ladies and gentlemen: Intel has it. :D

    Imo, it is easier to kidnap a family member to know "victim"`s secrets than to use the method described.

    Also, are you sure you wanted to post it here?

    TBH: the fail thread doesn't give you as much likes as posting it here. :D

    @mbk1969 : it's still one which may get abused by using other intrusion vectors and then using this to get data exfiltrated. I mean ... you can almost choose what you want and it's an Intel "feature", included in every CPU, so enabled by (de-)fault in a lot of devices.

    But to be fair: The same could happen with AMD. I don't want to do Intel-only bashing. Both have their flaws and I bet there are some 0-dayz for both already available for some secret service. Like the NSA toolkit showed us already ...

    I think, you got it "choose what you want" a bit wrong. Imo they only mean choose what chunk of cache memory to read - and that is far from "choose what you want" to read.

    Btw, after reading their sheet two thoughts came to me:
    1 - all these side channel vulnerabilities are about cache memory.
    2 - hence there is very simple solution to get rid of sensitive information in cache memory - archive some binary file (video or just trash) with size bigger than cache and - voila! - most of the cache is loaded with content of that archive file.

    Some Australiania, love this, there is an awesome movie 'The Castle'. This is sort of in that vibe.
    The band (Karma Country) is cool, they have 5 albums out :)
