There's only less than a page an a half in Google about this, dating back from mid-May.
So it's probably genuine, but considering the scarceness of information almost two weeks after the initial reports, I suspect it is just yet another virus rather than a major outbreak.
(Not much help if you got it though.... obviously )
Computer viruses are a bit like Ecoli---- they come in many forms and like bacteria can mutate if some "script kiddie " gets a hold of it and adds a bit of extra oomph to its nasty behaviour. So today's R66V may be a different =more lethal variant of the original.
