Distributed denial-of-service attacks are common and fairly easy to carry out, say security experts. A new crop of DDoS services enable just about anyone to conduct an attack just by identifying the organization or website they want to target and the length of time they want to flood it with unwanted traffic. Attacks are also growing in sophistication.
A recent study by cloud hosting provider Akamai found that malicious network traffic is getting more difficult to filter out from legitimate traffic. DDoS toolkits such as Dirt Jumper have components to bypass filtering appliances and security mechanisms designed to detect attacks. Prices for DDoS services range from $3 to $5 an hour and run up to $100 per day or $600 per week for the service.
