b]Prolexic, the global leader in Distributed Denial of Service (DDoS) protection services, today shared information on a popular cyber attack technique, SYN reflection attacks, which can leverage the defense mechanisms of DDoS mitigation devices to increase the strength of the attacks.
SYN reflection attacks are one of the more sophisticated DDoS attack methods and typically require some skill to execute. However, they have recently grown in popularity as they’ve become available on a DDoS-as-a-Service basis via the criminal underground.
“SYN reflection attacks have been around for a long time, but new attack apps make them extremely easy to launch.
