I think the key to discovering the real identity of this entity will be found in the name itself. Spooks and crypto people love to leave hints in their work because, generally, their minds are extremely quick and have the capability to see a bigger picture and the surrounding countryside. Crypt is high level math and who has some of the brightest math minds in the world?
So, I'd bet they left a "joke" in the name itself which is sort of like a signature that is "signing off" on their work. Like animators like to hide unrelated-to-subject images in their work.
Hope everyone is enjoying the tax break that some people got that has already been eaten by the oligarchs. What with higher oil prices and raised prices on a lot of other things (remember, you know who "they" are by how quickly they harvest your "extra income"), you are back to where you started from and they have all of the tax break money to increase their wealth (except for seniors, who got the shaft of increased costs but no extra disposable income).
As some wag said, years ago......Happy Mothers' Day to all you muthas out there.
