There's another variation of the NoName copycat shakedowns -
there's a group who aren't doing any DDoS, they're just getting the list of actual NoName victims, then emailing them as "NoName057" demanding Bitcoin for the attacks to stop.
Again, it's very unlikely it's actually NoName - the play appears to be, because NoName are super successful (by just doing layer 7), people are surfing off it for money from confused victims who don't even know what NoName is.
