Interesting that they’re mentioned as only being exploited on Intel. Has anyone seen whether that’s because the attacker only targeted that platform or is it actually stopped by something like pointer protection?
It might just be that the only machines they have information about are Intel? It doesn't say how many data points they have, but if it's only a handful then it's not at all surprising.
That’s what I was wondering: if this is like some of those Citizen Lab reports it might simply be that they have a small number of targeted individuals who noticed something and reported it.
