Akamai researchers say hackers have started abusing an obsolete routing protocol to launch distributed denial-of-service attacks. These attacks abused home and small business (SOHO) routers that still support Routing Information Protocol version 1 (RIPv1) This protocol is designed to allow routers on small networks to exchange information about routes. The source IP (Internet Protocol) address of such a request can be spoofed, so the responding routers can be tricked to send their information to an IP address chosen by attackers.”]
