Inside look at botnets
Found an interesting article from UCSB with details from when they were trying to take down the Cutwail botnet; one of the largest (known) in the world.
A little bit long, but I thought it was worth the read if you're interested in spam/botnet communities and tactics.
@MattKing that was a good read.
@JaredBusch Thanks, I always try to keep an eye on the black-hat and spam world; makes it easier to understand what we're defending against.
