Denial of Service Attacks Aren't Worth It Anymore

This is an interesting item from Symantec analyzing why Denial of Service (DoS) attacks aren't worthwhile anymore.

Basically, Symantec is saying that most DoS attacks come from botnets. If the bot herder isn't careful, a prolonged DoS attack can expose the bot controller. Once the controller is found, it can be taken down. The result: a DoS attack can lead to the bot herder losing the entire bot.
