> And still to this date not single spectre attack shown to work under real world conditions.
I find statements like yours difficult. Can we know that something did not happen just because nobody talked about it?
A vulnerability as deep and far reaching as Spectre is extremely interesting to nation-state level hacking groups as a means of warfare, we should not assume that we know about everything these actors are up to.
But if you treat well funded actors as essentially omnipotent entities, you might just as well lie down and give up. The reality is that although we don't know everything, there cannot be all that much activity, either, or we would see many more installations of well crafted exploits and rootkits than what currently gets reported. And I would expect blackhats to go for some reliable 0 day hack with small code size rather than relying on a complex attack that first needs to read memory locations in a roundabout way to get anywhere.
I'm not saying omnipotent, just much less transparent than the above comment suggests. I'm not sure how many exploits leak out of military cyber offense teams in China, Israel or the US.
