Akamai Technologies, Inc., provider of cloud services for delivering, optimizing and securing online content and business applications, has released a new cybersecurity threat advisory. The advisory alerts the security community, device vendors, Internet service providers and enterprises to the risk of massive distributed denial of service (DDoS) attacks involving Universal Plug and Play (UPnP) devices. PLXsert has observed the use of a new reflection and amplification DDoS attack that deliberately misuses communications protocols that come enabled on millions of home and office devices, including routers, media servers, web cams, smart TVs and printers. The protocols allow devices to discover each other on a network, establish communication and coordinate activities. DDoS attackers have been abusing these protocols on Internet-exposed devices to launch attacks that generate floods of traffic and cause website and network outages at enterprise targets.
