Attackers today use distributed denial-of-service attacks for everything from blackmailing businesses into paying uptime money to disrupting sites run by political opponents. Many cybercrime groups have also become expert at subverting legitimate sites, and using them to launch for-profit "DDoS as a service" attacks.
Much has changed since the early days of DDoS exploits, when not all attackers attempted to monetize their DDoS capabilities, says Richard Meeus, an enterprise security architect manager for content delivery network provider Akamai, which also sells DDoS mitigation services. "They were also used by script kiddies, the monetization part wasn't really used to a great extent at that point. We tended to see it as more from the hacktivist point of view," he tells Information Security Media Group. Those attack campaigns, furthermore, were more of a nuisance than a threat to the business. "The attack vector was very large, but the actual sizes were quite small, and the number of bots that you needed to create the attack was very large, but the actual effect was very easy to mitigate."
