Two weeks ago, we predicted that distributed denial-of-service (DDoS) attacks using Internet of Things Botnet armies would become more frequent and more severe. Unfortunately, these predications are quickly coming true. On October 21st, a massive DDoS attack was launched against New Hampshire-based DNS provider, Dyn. Hackers used a publicly available Mirai source code to create a Botnet army and infect an estimated 500,000 or more devices, overwhelming Dyn with enormous amounts of junk traffic. Major websites who use Dyn, like Amazon, Twitter, Spotify, and Netflix, were brought down for hours. What’s worse, these compromised devices remain accessible to hackers. An IoT device could be anything from a CCTV camera to a printer. The devices often have weak passwords, as most manufacturers and users are not concerned with securing their products. Many of the devices used in the attack were products of the Hangzhou Xiongmai Technology of China, and the company is now recalling some of its devices, and issuing patches for others.
