Solutionary said it found 75 percent of distributed denial-of-service (DDoS) attacks targeted SSL protected components of Web applications in 2012. This kind of attack, which is slightly more sophisticated than a traditional TCP/UDP-based DDoS attack, is harder to block, the firm said. A 10.5 hour attack on one financial services firm exceeded $65,000 to identify, respond and investigate the incident, Solutionary said. A DDoS attack can also be used as a tool to throw off security teams to the real problem. In some cases, DDoS was used to distract attention from a fraudulent wire transfer, Solutionary said.
