I tried replicating something along the lines of PoC 1 (in BASIC of all things), but couldn't get it to read the memory speculatively on an i7-860 from what I could see (it does reliably detect the cache misses when it is in proper code flow). Coming here I see I might need to learn more about branch prediction, I barely know what I'm doing. But after seeing news of this earlier today and reading the papers I thought it sounds worryingly easy, so the fact I got this far starting from scratch in a little over 3 hours (and if it had speculatively executed the read, I would have detected it) is kind of scary.
