#2Article title is slightly misleading: by smaller they mean process size, increasing the range of the rowhammer attacks logically due to decreased distance between memory cells even though the physics limited distance is the same.

#3Is there any evidence of Rawhammer being used in a successful attack in the wild?

According to the article, no.
What I want to know is if this works on ECC memory. I'm guessing not, which makes the "vulnerability" even more of a non-issue in mission-critical applications that likely moved to ECC a while ago.

I'm the author of the article.
With all due respect, but I will have to push back on your categorization as 'slightly misleading' here. Your explanation effectively explains the headline and is also what Google researchers said. How is the headline misleading?

Good question. what would the evidence be? memory errors? i wonder how easy to detect these would be

Apparently it does but I haven't tested it myself

#9In other words, blame Intel for trying to pass off ECC as a "Enterprise Feature" instead of the basic necessity that it is.

Yes, Rowhammer can bypass ECC. Forgot to include this in the article, mainly because there's so much Rowhammer research.
