I do not equate samples with attacks. I calculate ratios of attacks. When looking at the number of attacks, it is rather clear that they include morphed samples. The results can be skewed when the data presented by Statista is skewed.
Anyway, what is in your opinion the more precise percentage of ransomware attacks? I think that 10% (+- 5%) is reliable and rather conservative.
The open question is if this percentage is similar when we take into account only attacks on home users.
