If they awarded prizes for the best read about malware on the internet this would be the winner for me.
It is written in words that we can all understand (which usually doesn't happen) and in a sort of story like format, with even Capain Kirk getting a mention!
It is a totally unputdownable read. Your understanding of how malware works will increase tenfold just by reading this.
Scary thing is though, it's all true, so get yourself a cup of coffee and start reading this you'll be so glad you did....
