I presume you're correct. They're trying to create a digital equivalent of the red cross emblem and encourage others to make it the norm. It sounds unbelievable that it would be effective, but so does a white paint job and a red sticker on a vehicle.
Yes, but as I said in a separate comment elsewhere on this story, the sort of interesting question is, how do they extend the legal protection to this digital emblem? I smell a draft additional protocol in the pipeline.
A cynical person might even suggest that the mere existence of such emblems, which are actually ineffective at increasing digital security but rather only provide a legal framework for prosecution, would encourage false flag operations.
With that argument you could say that the red cross in the non-digital world encourages false flag operations.
I think it’s still much easier to attribute a physical attack than a digital one.
