Infosecurity - Fort Disco – a Botnet that Delivers Brute Force Logon Attacks: "Blogs and CMSs tend to be hosted in data centers with immense network bandwidth. Compromising multiple sites gives the attacker access to their combined bandwidth, much more powerful than a similarly sized botnet of home computers with limited network access by comparison." This makes a server botnet particularly attractive for delivering high volume spam and DDoS attacks.
