Aging networking protocols still employed by nearly every Internet-connected device are being abused by hackers to conduct distributed denial-of-service (DDoS) attacks.
Security vendor Prolexic found that attackers are increasingly using the protocols for what it terms "distributed reflection denial-of-service attacks" (DrDos), where a device is tricked into sending a high volume of traffic to a victim's network.
"DrDos protocol reflection attacks are possible due to the inherent design of the original architecture," Prolexic wrote in a white paper. "When these protocols were developed, functionality was the main focus, not security."
Government organizations, banks and companies are targeted by DDoS attacks for a variety of reasons. Hackers sometimes use DDoS attacks to draw attention away from other mischief or want to disrupt an organization for political or philosophical reasons.
