DDoS Attack Takes Down Netflix, Twitter

An October DDoS attack – which was launched through IoT devices and blocked an array of websites - deepened the industry's concerns over the security risk of the Internet of Things.

The denial of service attack was launched through Internet of Things consumer devices, including webcams, routers and video recorders, to overwhelm servers at Dynamic Network Services (Dyn) and led to the blockage of more than 1,200 websites.

The attack on Dyn, which connects users to websites such as Twitter and Netflix, came from tens of millions of addresses on devices infected with malicious software codes, knocking out access by flooding websites with junk data.
