Another case of journalistic 'obviousness'...of course the miscreants are going to beef up their crapware when they hear that it can be circumvented...which is why all these announcementnthat so and so ransomware can be decrypted, etc., is really counter productive.

Well, I suppose that even ransomware must get tired of riding in the same 'car'...but seriously...regardless of the transportation mechanism if the basic steps are followed then one is somewhat safer.
