One of the world’s largest spam botnets has finally been eradicated. At its peak – as recently as January 2012 – the Grum botnet was the largest spamming network in the world.
Spam levels worldwide are expected to drop as a result, although it seems probable that newer, more sophisticated botnets will rise to take Grum’s place. Enjoy the respite while you can.
